Heaps do lie: debugging a memory leak in vLLM.

A few months ago, our team investigated a suspected memory leak in vLLM. At first, we thought the issue would be easy to spot, something confined to the upper layers of the codebase. But the deeper we looked, the more complex it became. This article kicks off our new Engineering Deep Dive series, where we’ll share how we tackle technical investigations and build solutions at Mistral AI.

AI in abundance

We’re taking new steps in our mission to bring frontier AI in the hands of everyone. Today, we are releasing:

Introducing: Devstral 2 and Mistral Vibe CLI.

Today, we're releasing Devstral 2—our next-generation coding model family available in two sizes: Devstral 2 (123B) and Devstral Small 2 (24B). Devstral 2 ships under a modified MIT license, while Devstral Small 2 uses Apache 2.0. Both are open-source and permissively licensed to accelerate distributed intelligence.

Le Chat. Custom MCP connectors. Memories.

The widest enterprise-ready connector directory (beta), with custom extensibility, making it easy to bring workflows into your AI assistant.

Rails testing on autopilot: Building an agent that writes what developers won't

In most large Rails monoliths, organizations prioritize writing new features over writing tests for them. Over time, more and more code goes untested, forcing teams to spend more time debugging painful bugs.

Workflows for work that runs the business

Today, we're releasing Workflows in public preview. Workflows is the orchestration layer for enterprise AI. It brings the durability, observability, and fault tolerance required to move AI-powered processes from proof of concept to production reliably. Organizations like ASML, ABANCA, CMA-CGM, France Travail, La Banque Postale, Moeve, and many more are already running Workflows to automate critical processes.

Introducing Mistral OCR 3

Breakthrough performance: 74% overall win rate over Mistral OCR 2 on forms, scanned documents, complex tables, and handwriting.

Unlocking the potential of vision language models on satellite imagery through fine-tuning

Fine-tuning foundation models is transforming how we apply AI to real-world problems. By adapting pre-trained models to specific domains, we can unlock dramatically better performance on specialized tasks. Today, we’re excited to share how fine-tuning Pixtral-12B on satellite imagery leads to significant improvements over the base model, showcasing the power of domain-specific adaptation.

Mistral Small 3

Today we're introducing Mistral Small 3, a latency-optimized 24B-parameter model released under the Apache 2.0 license.

Make Memory work for you.

As conversational AIs get more capable, our expectations grow with them. We don’t just want faster answers, we want tools that remember, adapt, and fit the way we work. That’s where Memories (beta) come in. And with it, new questions: What should an AI remember? How should it recall? And what does it take for you to trust it?
