2023 – 2026

Mistral Versions

Mistral's current largest dense open-weights model is Mistral Medium 3.5, released April 28, 2026 — 128B dense parameters, 256K context, multimodal, the lab's first "flagship merged model" (chat / reasoning / coding / vision in one). The open-weights granular-MoE frontier above it is held by Mistral Large 3 (December 2, 2025; 41B-active / 675B-total, Apache 2.0). I track every Mistral release here — from Mistral 7B in September 2023 onward — with HuggingFace ids, ship dates, family (Open / Research / Proprietary), and license terms. Below the table: the April 2023 founding by Mensch, Lample, and Lacroix, the funding arc through ASML's September 2025 €1.7B Series C, the February 2024 Microsoft partnership and the EU regulatory friction, the EU AI Act lobbying narrative, and the January 2025 Apache 2.0 turn at Mistral Small 3.

Robostral Navigate
Robostral Navigate — 8B embodied-navigation VLM; enterprise access, no open weights or public API string at launch
Proprietary
Current
Jul 8, 2026
Mistral's first embodied-navigation / physical-AI model. 8B vision-language model; single RGB camera, no LiDAR; hardware-agnostic across wheeled / legged / flying robots. 76.6% success on R2R-CE (validation unseen). Enterprise access.
  • Released July 8, 2026; the announcement is at mistral.ai/news/robostral-navigate, and the legal center's AI-governance page independently gives the same July 8, 2026 release date, classifying it a Specialized Model with status Active and no retirement date — the only Mistral surface besides the blog post that documents the model at all. Mistral's first model built for embodied navigation — the lab's entry into physical / robotics AI, following the May 2026 acquisition of Austria-based physics-AI startup Emmi AI (~30 researchers).
  • 8B vision-language model. Takes RGB images plus a plain-language instruction (e.g. “go to the loading dock”) and moves a robot through the environment from a single standard RGB camera — no depth cameras, LiDAR, or multi-sensor arrays. Hardware-agnostic across wheeled, legged, and flying robots.
  • Trained entirely in simulation on ~400,000 trajectories across 6,000 scenes. On the R2R-CE continuous-navigation benchmark it reports 79.4% success on validation-seen and 76.6% on validation-unseen, which Mistral says outperforms the best single-camera baseline by 9.7 points and the best multi-sensor systems by 4.5 points.
  • Family / license: filed under Proprietary. At launch the announcement offers only an enterprise “talk with our team” access path — no open weights on the mistralai HuggingFace org, no Apache / open license, and no la Plateforme API model string. Re-checked July 31, 2026: still no docs model card (/models/model-cards/robostral-navigate and the dated variants all 404), still no HuggingFace repo, and the model does not appear in the docs' All-models list — so there is no copy-pasteable identifier to publish here. If open weights or an API string appear in a later refresh, the family pill and model string should be revisited.
  • Does not change Mistral's general-purpose flagship (Mistral Medium 3.5, April 2026) or the open-weights granular-MoE frontier (Mistral Large 3, December 2025); Robostral Navigate is a specialized physical-AI product in a new product slot.

mistralai/Leanstral-1.5-119B-A6B (Apache 2.0), labs-leanstral-1-5 (free API)
Open
Current
Jun 30, 2026
Major upgrade to the Lean 4 formal-proof agent. 119B total / 6B active MoE, Apache 2.0. Saturates miniF2F, solves 587/672 PutnamBench, SOTA on FATE-H (87%) / FATE-X (34%).
  • Released June 30, 2026; the announcement is at mistral.ai/news/leanstral-1-5; model card at docs.mistral.ai/models/model-cards/leanstral-1-5; weights at mistralai/Leanstral-1.5-119B-A6B.
  • 119B total / 6B active parameters (Mixture-of-Experts). A major performance upgrade to the original Leanstral (March 2026) for formal proof engineering in Lean 4. Trained through mid-training, supervised fine-tuning, and reinforcement learning with CISPO across multiturn-verifier and code-agent RL environments.
  • State-of-the-art formal-reasoning results — saturates miniF2F (100% on validation and test), solves 587/672 PutnamBench problems at ~$4/problem, and sets a new SOTA on FATE-H (87%) and FATE-X (34%). On the fully open-sourced FLTEval it lifts pass@1 from 21.9 to 28.9 and pass@8 from 31.9 to 43.2, surpassing Opus 4.6's 39.6 at one-seventh the cost.
  • Real-world code verification — proved O(log n) time-complexity guarantees for an AVL-tree implementation over 2.7M tokens and 22 compactions, and uncovered 11 genuine bugs (5 previously unreported) across 57 tested repositories via an Aeneas-to-Lean pipeline.
  • License: Apache 2.0, commercial and research use; free API ($0 / M tokens), 256K context. Recommended for use in Mistral Vibe (/leanstall, vibe --agent lean). Supersedes the original Leanstral (labs-leanstral-2603, March 2026), which was retired June 30, 2026.
  • Three source discrepancies worth knowing, all inside Mistral's own material. Ship date — the docs model card and the changelog both date the release June 30, 2026, while the launch post carries a July 2, 2026 byline (the HuggingFace repo was created July 1); the date above follows the two-of-three card-plus-changelog majority, the same rule this page applies to Mistral Medium 3.5. API string — the launch post calls the endpoint leanstral-1-5, while the docs model card and changelog both give labs-leanstral-1-5 (the labs- prefix every Labs-tier model carries); the docs string is the one used above. Active parameters — the post and the HuggingFace repo name (-A6B) say 6B; the model card says 6.5B.
  • Lifecycle: the model card marks Leanstral 1.5 Public Preview, not GA — the only non-GA model in Mistral's current list as of July 31, 2026 (Mistral Medium 3.5, Mistral Small 4, Mistral Large 3, Voxtral TTS, OCR 4, OCR 3, Codestral 25.08, and both Voxtral Mini Transcribe 2 endpoints all carry GA). A specialized formal-proof agent on a preview endpoint, so it is not a general-purpose flagship no matter how recent the ship date.
  • Mistral pre-announced a retirement date of September 30, 2026 for the endpoint in the same changelog entry that released it — a roughly three-month published lifespan, and a reminder that Labs-tier models are not covered by the deprecation notice period the Premier line gets. The Apache 2.0 weights are unaffected.

Jun 23, 2026
State-of-the-art document intelligence. Bounding boxes, block classification, inline confidence scores. 170-language support. Single-container self-hosted deployment. $4 / 1,000 pages.
  • Released June 23, 2026; the announcement is at mistral.ai/news/ocr-4; docs model card at docs.mistral.ai/models/model-cards/ocr-4-0.
  • Structure-aware document intelligence — where prior OCR generations focused on text extraction, OCR 4 returns a full structural representation: paragraph-level bounding boxes, typed block classification (titles, tables, equations, signatures, and more), and inline confidence scores per page and per word. Enables citation-grounded RAG, redactions, form-filling agents, and human-in-the-loop verification pipelines.
  • 170-language support across 10 language groups (English, Western Europe, Eastern Europe, Middle Eastern, Chinese, East Asian, Southeast Asian, and specialized/low-resource languages). Top score on OlmOCRBench (85.20) and OmniDocBench (93.07) among tested systems; independent annotators preferred OCR 4 output in 72% of head-to-head document comparisons.
  • Self-hosted deployment — compact enough to run in a single container, keeping sensitive document data within the customer's own infrastructure. Available to enterprise customers. Also available via la Plateforme, Amazon SageMaker, and Microsoft Foundry.
  • Pricing: $4 / 1,000 pages (API); $2 / 1,000 pages (Batch API, 50% discount); $5 / 1,000 pages (Document AI with structured JSON output). Integrated as the ingestion component of Mistral's Search Toolkit for RAG and enterprise search pipelines.
  • Supersedes Mistral OCR 3 (mistral-ocr-2512, December 2025) in the OCR product slot; OCR 3 status moves to Available.

Apr 28, 2026
Mistral's largest dense open-weights model. 128B dense, 256K context, multimodal, “first flagship merged model” (chat / reasoning / coding / vision in one). Modified MIT license.
  • Released April 28, 2026; the model card is at docs.mistral.ai/models/model-cards/mistral-medium-3-5-26-04; weights on HuggingFace at mistralai/Mistral-Medium-3.5-128B. The la Plateforme string is mistral-medium-3-5 (the -26-04 suffix belongs to the docs URL, not the API); the announcement rode the May 22, 2026 Vibe remote-agents post.
  • 128B dense parameters, 256K context. The largest dense open-weights model Mistral has shipped to date, replacing the prior closed-weights Mistral Medium 3 in the medium-product slot.
  • First “flagship merged model” — consolidates instruction-following, reasoning, coding, and vision into a single set of weights, scoring 77.6% on SWE-Bench Verified.
  • License: Modified MIT — the open-licensing arc that started at Mistral Small 3 (January 2025) and was formalized across the Mistral 3 family (December 2025) extends to the medium product slot for the first time.
  • Pricing on la Plateforme: $1.50 / M input, $7.50 / M output; also self-hostable from HuggingFace.
  • Shipped alongside Le Chat Work mode (a multi-step agent for research, analysis, and cross-tool actions) and Vibe remote coding agents (async cloud-spawned coding sessions from the CLI or Le Chat). The Voxtral V2 speech models (February 2026) and Voxtral TTS (March 2026) carry their own rows below.

Mistral's first text-to-speech model. 4B streaming TTS, 9 languages, preset voices + zero-shot voice cloning, ~70 ms model latency. Open weights under CC BY-NC 4.0; commercial use via la Plateforme.
  • Released March 23, 2026 — the docs model card, the changelog, and the launch-post byline all agree on the date; the announcement is at mistral.ai/news/voxtral-tts; model card at docs.mistral.ai/models/model-cards/voxtral-tts-26-03; weights at mistralai/Voxtral-4B-TTS-2603; coverage in MarkTechPost.
  • 4B streaming text-to-speech — the lab's first audio-generation model, complementing the Voxtral speech-understanding line. Generates speech in 9 languages (English, French, German, Spanish, Dutch, Portuguese, Italian, Hindi, Arabic), with preset voices in the API and zero-shot voice cloning from a reference clip as short as 3 seconds; it also does zero-shot cross-lingual voice adaptation it was not explicitly trained for. Natively generates up to two minutes of audio.
  • License — CC BY-NC 4.0 (non-commercial) on the open weights, the first Mistral release under a non-commercial open-weight license. Filed under Research here (the page's restricted-commercial open-weight tier) because the weights are public but commercial use is not permitted under CC BY-NC; commercial use runs through the la Plateforme API. The docs model card carries the GA lifecycle badge and the CC BY-NC 4.0 license badge; pricing is $16 / M characters.
  • Two source discrepancies inside Mistral's own material, both re-checked July 31, 2026. API string — the docs model card's copy-to-clipboard identifier is voxtral-mini-tts-2603 (with one further alias hidden behind a “+1” chip), while the changelog entry announces the model as voxtral-tts-2603; the card string is the one used above, per this page's prefer-the-model-card rule for anything a developer pastes into code. Latency — the launch post reports a 70 ms model latency for a typical 10-second / 500-character input (real-time factor ≈9.7×), while the model card's one-line description says ~90 ms time-to-first-audio.

  • Released March 16, 2026; the announcement is at mistral.ai/news/mistral-small-4.
  • First Mistral Small with Mixture-of-Experts — 119B total parameters with 6B active per token; the prior Mistral Small lineage (Small 3 / 3.1) was dense at 24B.
  • License: Apache 2.0; weights at mistralai/Mistral-Small-4-119B-2603, served on la Plateforme as mistral-small-2603. Mistral's docs describe it as a hybrid model unifying instruct, reasoning, and coding in one multimodal model with a 256K context window.

  • Released March 16, 2026; weights at mistralai/Leanstral-2603; model card at docs.mistral.ai; coverage in The Register.
  • First open-source code agent for Lean 4 — built for formal proof engineering in realistic repositories. 119B total parameters with 6.5B active per token (Mixture-of-Experts). Three deployment paths: Mistral Vibe (/leanstral), a free labs-leanstral-2603 API endpoint, or self-host from the Apache 2.0 weights.
  • License — Apache 2.0, commercial and research use. On Mistral's FLTEval suite (proof tasks drawn from the Fermat's Last Theorem formalization project) it scores 26.3 at pass@2 for ~$36, ahead of Claude Haiku (23.0, $184) and Sonnet (23.7, $549) per the launch benchmarks.
  • Superseded by Leanstral 1.5 in the Lean-proof product slot. Mistral's model card gives a retirement date of June 30, 2026 for labs-leanstral-2603, so the API endpoint is gone; status is Legacy. The Apache 2.0 weights remain downloadable at mistralai/Leanstral-2603 for self-hosting.

  • Released December 11, 2025 with no launch blog post — the release surfaced only through the docs changelog and the model card at docs.mistral.ai/models/model-cards/mistral-small-creative-25-12. The card dates the release December 11; the changelog entry says December 16. The card's date is used above.
  • Experimental small model for creative writing — narrative generation, roleplay and character-driven dialog, general instruction following, and conversational agents, trained on what Mistral describes as “meticulously curated data.” 32K-token context window.
  • Labs tier, API only — served free as labs-mistral-small-creative (no dated version suffix). Unlike the other Labs releases on this page (Leanstral, Leanstral 1.5), no weights were ever published to the mistralai HuggingFace org, so the row is filed under Proprietary.

Open-weights coding-agent line. Devstral Small 2 is a 24B dense Apache 2.0 release claimed to beat Qwen 3 Coder Flash. Both endpoints deprecated in 2026; the weights remain downloadable.
  • Released December 9, 2025; the announcement is at mistral.ai/news/devstral-2-vibe-cli; coverage in VentureBeat.
  • Devstral Small 2 is a 24B dense model, Apache 2.0, designed for laptop-scale agentic coding deployment; Mistral claimed it beats Qwen 3 Coder Flash on coding benchmarks.
  • Devstral 2 is the larger production-scale variant (123B, mistralai/Devstral-2-123B-Instruct-2512), shipped under Mistral's Modified MIT license rather than Apache 2.0 — the docs model card carries the Modified MIT badge and the HuggingFace repo is tagged license:other, where Devstral Small 2's repo is tagged apache-2.0. It moved to paid API access as devstral-2512 in January 2026.
  • Builds on the original Devstral Small (May 2025) that established the Devstral coding-agent lineage. Shipped alongside the Devstral Vibe CLI.
  • Both endpoints are deprecated. The model cards give devstral-2512 as deprecated May 22, 2026 and labs-devstral-small-2512 as deprecated February 27, 2026, both naming Mistral Medium 3.5 as the replacement; as of July 31, 2026 neither appears in the docs' current model list and both sit in the Deprecated & retired table. The July 31, 2026 retirement date the docs published for devstral-2512 in mid-July stayed withdrawn through the day itself — re-checked on July 31, 2026, neither card publishes a retirement date and the legal center's lifecycle table says N/A / Active, so the endpoints are still served. Status is Legacy on the deprecation reading this page uses; the open weights remain downloadable and are unaffected.

The original June row (#magistral) covers the Magistral Small (Apache 2.0) + Magistral Medium 1.0 launch event.
  • The end of the Magistral reasoning line. The model card lists magistral-medium-2509 as deprecated May 22, 2026 and names Mistral Medium 3.5 — a general model with an adjustable reasoning_effort parameter — as the replacement, rather than a Magistral successor. As of July 31, 2026 the docs' Deprecated & retired table carries every Magistral release (Medium and Small, 1.0–1.2) and no Magistral appears in the docs' current model list. The Magistral Small 1.2 sibling was deprecated a little earlier, April 30, 2026, pointing at Mistral Small 4. Status is Legacy. The endpoint is still served — no retirement date is published for 1.2 on the model card, and the legal center's lifecycle table (which shows Medium 1.0 and 1.1 retired October 31, 2025) still lists it active — but Mistral no longer recommends it for any workload.

First Voxtral audio models. Multimodal audio chat (speech + text), 24B + 3B, Apache 2.0, 32K context (audio up to ~40 min). State-of-the-art speech understanding at launch.
  • Released July 15, 2025; the announcement is at mistral.ai/news/voxtral; technical report arXiv 2507.13264; weights at huggingface.co/mistralai.
  • Two multimodal audio-chat models — Voxtral Small (24B, production-scale) and Voxtral Mini (3B, local / edge) comprehend spoken audio and text together while retaining strong text ability. A 32K context handles audio up to ~40 minutes and long multi-turn conversations.
  • License: Apache 2.0 for both sizes. The foundation of the Voxtral audio line; superseded for the transcribe / realtime slot by Voxtral V2 (February 2026).
  • The two halves have diverged on lifecycle. Voxtral Small is still marked GA on its model card and still appears in the docs' current model list, while Voxtral Mini (voxtral-mini-2507) was deprecated February 27, 2026 in favor of Voxtral Mini Transcribe 2. Because the Small variant is still supported, the row stays Available.

The April 2023 founding

Mistral AI was incorporated in Paris on April 28, 2023 by three French AI researchers in their early thirties. Arthur Mensch (CEO) had been a researcher at Google DeepMind, where he co-authored the original LLaMA-related research; Guillaume Lample (Chief Scientist) and Timothée Lacroix (CTO) had worked on the LLaMA paper at Meta. The three had attended École polytechnique together a decade earlier.

Mistral's seed round closed in June 2023 at €105 million ($117M USD) — an unusual scale for a four-week-old company, valuing the lab at roughly $260M pre-product. Lead investor was Lightspeed Venture Partners; the syndicate included Eric Schmidt, Xavier Niel (Iliad / Free), JCDecaux Holding, and Bpifrance (the French sovereign investment bank). The seed-round valuation drew sustained press coverage as a marker of European AI capital commitment.

The first model, Mistral 7B, shipped on September 27, 2023 — five months after incorporation. It was released via a magnet link posted to X, a deliberate stylistic choice that the lab repeated for Mixtral 8x7B in December 2023. The release-by-torrent pattern signaled an open-source identity that the subsequent licensing turn at the Microsoft partnership and the Mistral Research License would complicate.

The funding arc — from ASML's September 2025 Series C to the March 2026 debt round

After the June 2023 seed, Mistral raised a $415M Series A in December 2023 led by Andreessen Horowitz at a ~$2B valuation. A €600M (~$640M) round in June 2024 mixed equity and debt, led by General Catalyst, valued the lab at roughly $6B. The headline fundraise came on September 9, 2025: a €1.7 billion (~$2B) Series C led by Dutch semiconductor company ASML, with ASML contributing €1.3 billion for a ~11% fully-diluted stake alongside NVIDIA, Andreessen Horowitz, Bpifrance, DST Global, General Catalyst, Index Ventures, and Lightspeed, valuing Mistral at €11.7 billion (~$13.8B).

ASML's strategic position in EUV lithography for advanced semiconductor fabrication makes the investment substantively unusual: the deal is widely read as a Europe-on-Europe sovereignty bet, ASML buying a stake in the European frontier-AI tenant most likely to consume next-generation compute that ASML's lithography ultimately enables. The Series C remains Mistral's largest single equity round and the largest European AI investment to date. The lab has not publicly disclosed gross revenue or operating margin.

On March 30, 2026 Mistral closed an $830 million debt financing from a seven-bank consortium including Crédit Agricole CIB, HSBC, and MUFG (first investments in Mistral for each), earmarked for a 44 MW data center near Paris built on 13,800 NVIDIA GB300 GPUs, alongside Swedish capacity. The lab has publicly targeted 200 MW of European capacity by end-2027. See TechCrunch and CNBC.

On June 12, 2026, Bloomberg reported that Mistral is in early-stage talks to raise roughly €3 billion (~$3.5B) at a valuation of about €20 billion (~$23B) — nearly double the €11.7B Series C mark from September 2025 — reportedly to fund the lab's new “physics AI” push for industrial engineering (anchored by the May 2026 acquisition of physics-modeling startup Emmi). The talks firmed up through July: on July 22, 2026 the Financial Times reported that Samsung Electronics is in talks to invest up to €1 billion in the round, with Swedish investor EQT also reportedly participating, at the same roughly €20 billion valuation — specifically EQT's Scaleup Europe Fund, per the FT via Axios, which frames the talks against an industry-wide memory-and-semiconductor crunch. Follow-on reporting has since added Novo Holdings and Santander to the list of reported participants. Neither Samsung nor Mistral has confirmed, the terms could change, and no new equity round had closed as of July 31, 2026. The September 2025 ASML-led Series C remains the most recent closed equity round.

The Microsoft partnership — February 2024 to the July 2026 compute expansion

On February 26, 2024, Microsoft and Mistral jointly announced a multi-year strategic partnership coinciding with the launch of Mistral Large on Azure AI. The deal carried a $16 million financial commitment from Microsoft and made Mistral models available natively on Azure as a preferred-partner offering, alongside OpenAI's models.

The partnership drew immediate French-government and EU regulatory scrutiny. The European Commission opened a brief antitrust look at whether the Microsoft commitment constituted a notifiable concentration under EU merger control; the Commission ultimately concluded it did not. Critics in Euronews coverage framed the deal as compromising the “European AI sovereignty” positioning the French government had used to justify its support of Mistral, including in the EU AI Act lobbying campaign covered in the next section.

Mensch's response (in a February 2024 Time interview and subsequent media appearances) framed the Microsoft deal as a commercial-distribution arrangement that did not affect Mistral's research direction or its open-source releases. The empirical record bears this out partially — the Mixtral 8x22B Apache 2.0 release in April 2024 followed two months later, and the Mistral 3 family relaunch in December 2025 re-committed the line to permissive open-source licensing across every scale — though the Mistral Large proprietary tier on Azure has remained a continuous commercial product.

On July 21, 2026, the partnership expanded substantially — and the infrastructure relationship now runs both ways. Microsoft announced a multibillion-dollar agreement to buy compute capacity from Mistral: Microsoft will lease part of Mistral's expanded Europe-based GPU infrastructure — built on thousands of NVIDIA Vera Rubin GPUs — to serve Azure cloud and AI demand, rather than only distributing Mistral's models on Azure. In the same announcement, Mistral Medium 3.5 and Mistral OCR 4 became available in Microsoft Foundry and Medium 3.5 in Microsoft Copilot Studio, deployable across cloud, cloud-connected, and fully disconnected Azure / Azure Local environments. Microsoft framed the deal under its Sovereign Cloud approach and its 2025 European Digital Commitments; no equity component was announced. Sources: Microsoft's July 21, 2026 release; France 24.

The EU AI Act lobbying narrative

Through late 2023 and into early 2024, Mistral mounted a sustained lobbying campaign against the European Parliament's tiered-foundation-model proposal in the EU AI Act, which would have imposed compliance and transparency obligations on general-purpose AI providers above defined capability thresholds. The campaign was led by Cédric O, France's former Secretary of State for Digital Affairs (2019–2022), who had joined Mistral as a strategic advisor and lobbyist after leaving government. Reporting at the time in Corporate Europe Observatory documented the privileged-access dynamic between Mistral and the highest levels of the French and German governments.

Mistral's stated position (in a November 2023 TechCrunch interview) was that the AI Act should regulate applications of AI rather than foundation models — that capability thresholds applied at the model-developer level would chill European open-source frontier-model development and entrench U.S. incumbents whose compliance teams were already large enough to absorb the regulatory cost. Critics countered that the “regulate applications, not models” framing aligned conveniently with the lobbying interests of the largest model developers themselves, which by 2025 included Mistral.

The final EU AI Act, agreed in December 2023 and entering force in August 2024, includes obligations on general-purpose AI providers but also includes broad exemptions for open-source models that do not pose “systemic risk.” The exemptions are widely credited — including by Corporate Europe Observatory's investigation — to the lobbying campaign Mistral led. The systemic-risk threshold, by contrast, captures the largest models and so applies to Mistral Large 2 / Mistral Large 3 onward; how the Code of Practice and the AI Office's compute-threshold methodology will treat each Mistral release is a continuous compliance question for the lab. Mistral said it would sign the GPAI Code of Practice within days of the Code's July 10, 2025 publication (EU Perspectives), and the AI Office's enforcement powers over general-purpose AI providers — including fines of up to 3% of global turnover or €15 million — activate on August 2, 2026.

The licensing turn — from MRL back to Apache 2.0

Mistral's licensing has evolved across three distinct conventions. The founding lineage — Mistral 7B (September 2023), Mixtral 8x7B (December 2023), Mixtral 8x22B (April 2024), Mistral NeMo (July 2024), Codestral Mamba and Mathstral (July 2024), Pixtral 12B (September 2024) — shipped under the standard Apache 2.0: weights public, commercial use unrestricted. In parallel, the proprietary tier (Mistral Medium December 2023, Mistral Large February 2024 onward) shipped closed-weights via la Plateforme.

The licensing innovation arrived in May 2024 with Codestral 22B, which introduced the bespoke Mistral AI Non-Production License (MNPL): weights public on HuggingFace, but commercial / production deployment requires a separate Mistral Commercial License. The MNPL pattern was generalized into the Mistral Research License (MRL), which was applied to Mistral Large 2 (July 2024) and Pixtral Large (November 2024). The MRL/MNPL pattern is the one tracked by the violet “Research” family pill on this page.

The licensing turn arrived on January 30, 2025 with Mistral Small 3, which returned to Apache 2.0. Most subsequent Mistral open releases have shipped under Apache 2.0: Mistral Small 3.1, Mistral Small 3.2, Devstral, Devstral Small 1.1, Devstral Small 2, Magistral Small, Mistral Large 3, the Ministral 3 family (3B / 8B / 14B), Mistral Small 4, and Leanstral / Leanstral 1.5. The December 2025 “Mistral 3” family relaunch formalized the Apache 2.0 commitment across every scale — including, notably, the 675B-total-parameter Mistral Large 3 frontier flagship, which is the largest open-weights Mistral model to date and was explicitly framed at launch as a return to permissive open-source.

Two 2026 releases sit outside the Apache 2.0 default without being proprietary, which is the reason the Family column's three pills no longer map one-to-one onto license names. Devstral 2 (December 2025) and Mistral Medium 3.5 (April 2026) both ship open weights under a Modified MIT license — the docs model cards carry a “Modified MIT” badge and both HuggingFace repos are tagged license:other rather than apache-2.0. Voxtral TTS (March 2026) ships open weights under CC BY-NC 4.0, which bars commercial use outright. This page files the two Modified MIT releases under the sky Open pill (commercial use is permitted) and Voxtral TTS under the violet Research pill (weights public, commercial use restricted); read the per-model license text before shipping at scale rather than inferring it from the pill.

The proprietary tier remains active in parallel: Codestral 25.01 (January 2025), Codestral 25.08 (July 2025), Mistral Medium 3 (May 2025), Mistral OCR 2 (May 2025), Mistral Medium 3.1 (August 2025), Magistral Medium 1.0–1.2 (June–September 2025), Mistral Saba (February 2025), Mistral OCR / OCR 2 / OCR 3 / OCR 4, and Voxtral TTS (March 2026) all ship closed-weights via la Plateforme. The hybrid model — Apache 2.0 open releases for the public-facing flagship lineage, proprietary closed-weights for specialized commercial products (including the entire Codestral line from version 25.01 onward) — is the licensing equilibrium Mistral has settled into.

The 2026 release cadence and the NVIDIA partnership

Mistral's release rhythm accelerated through early 2026. In March 2026 alone, the lab shipped six major products in roughly two weeks: Mistral Small 4 (March 16), the Devstral Vibe CLI, Voxtral TTS (March 23, the lab's first audio model), Forge, the Spaces CLI, and a publicly-announced NVIDIA partnership for inference-stack optimization across the Mistral lineage on NVIDIA Blackwell hardware.

The cadence reflects the engineering capacity unlocked by the September 2025 ASML round and the Microsoft / NVIDIA / hyperscaler distribution deals collectively. Whether the cadence is sustainable through 2026 is an open question; the prior Mistral release rhythm averaged roughly 6–10 model rows per year, and the March 2026 wave represented an outlier rather than a new steady state. After Mistral Medium 3.5 (April 28, 2026), the spring focus shifted from model launches to product surface, with the changelog recording platform work (Vibe, Connectors, Workflows, Search Toolkit). The next model release was Mistral OCR 4 (June 23, 2026) — a specialized document-intelligence model, not a general-purpose LLM. On July 8, 2026 the lab shipped Robostral Navigate (mistral.ai/news/robostral-navigate), its first embodied-navigation model and the first shipped product of the physics-AI push begun with the May 2026 Emmi acquisition — an 8B vision-language model that steers a robot from a single RGB camera and a plain-language instruction, again a specialized model rather than a general-purpose LLM. The NVIDIA relationship deepened past inference-stack optimization on July 21, 2026, when the expanded Microsoft agreement (covered in the Microsoft section above) had Mistral deploying thousands of NVIDIA Vera Rubin GPUs in its European data centers, part of whose capacity Microsoft will lease for Azure.

On May 28, 2026, at its inaugural AI Now Summit in Paris, Mistral rebranded Le Chat as Vibe (mistral.ai/news/vibe-agent) — a single agent spanning Work mode (long-horizon productivity across Google Workspace, Outlook, SharePoint, Slack, and GitHub connectors), Code mode (remote coding agents and a VS Code extension), and a legacy Chat mode that preserves the prior Le Chat experience and history. The summit also introduced an industrial “physics AI” stack — built on the May 2026 acquisition of Emmi — targeting aerospace, automotive, and semiconductor engineering, with Airbus, BMW, and ASML named as customers. Both are product / platform developments rather than language-model releases, so neither adds a table row.

Where to run Mistral

Mistral is widely deployed because most flagship releases are open-weights and the proprietary releases are available across every major hyperscaler. Inference paths through 2025–2026 break into four categories.

Mistral's own surfaces. Vibe — the rebrand of Le Chat announced May 28, 2026 (mistral.ai/news/vibe-agent) — is the consumer + agent product (free / Pro $14.99 / Team $24.99 / Enterprise, iOS / Android / web), with Work, Code, and Chat modes; existing Le Chat history, settings, and plans carried over. la Plateforme (Mistral Studio) is the developer API endpoint (OpenAI-compatible).

Self-host from HuggingFace. Download from the mistralai org and run with vLLM, llama.cpp, Ollama, or NVIDIA TensorRT-LLM. The Apache 2.0 releases (everything from Mistral 7B through Mistral Small 4) self-host without commercial restriction; the MRL releases (Codestral 22B, Mistral Large 2, Pixtral Large) require a separate commercial license for production use.

Hyperscalers. Microsoft Azure AI Foundry (the Microsoft launch partner since February 2024), AWS Bedrock, Google Cloud Vertex AI, IBM watsonx, Oracle OCI, NVIDIA NIM (the Mistral NeMo launch partner since July 2024). Most hyperscalers carry both the proprietary and the open-weights lineage; the per-model availability matrix lives at docs.mistral.ai.

Hosted-inference providers. Together AI, Fireworks, OpenRouter, Replicate, Groq. Most providers serve the Apache 2.0 lineage with similar latency / cost characteristics; the MRL-licensed weights (Mistral Large 2, Pixtral Large) typically require an additional commercial-license attestation from the provider.

Not a corporate officer; Mistral's regulatory voice in Brussels.

The competitive landscape

Mistral occupies a distinctive position: the leading European frontier-AI lab, with a hybrid commercial strategy that puts open-weights flagships (Apache 2.0 from Mistral Small 3 onward) alongside a proprietary API tier on la Plateforme and the hyperscalers. The closest open-weights competitors are Meta's Llama (custom Llama Community License with the >700M-MAU carve-out, see Llama Versions), DeepSeek (Chinese, MIT-licensed for the V3 / R1 line and onward, see DeepSeek Versions), and Alibaba's Qwen (Apache-2.0-or-permissive across most releases — see Qwen Versions). The closed-weights frontier competitors — ChatGPT, Claude, Gemini, Grok — have all stayed closed-weights since their inception. Mistral's regulatory and political position in Europe is the variable that distinguishes the line from every other frontier lab; whether the EU AI Act's Code of Practice and the AI Office's enforcement methodology will treat European model providers more or less stringently than U.S. and Chinese ones remains the open structural question for the lab through 2026.
