Evaluating RAG with LLM as a Judge

Large Language Models (LLMs) are rapidly becoming essential tools for creating widely-used applications. But making sure these models perform as expected is much easier said than done. Evaluating LLM systems isn't just about verifying the outputs are coherent, but also about making sure the answers are relevant and meet the necessary requirements.

Mistral batch API

This could've been a tweet, but... While the AI developer community was faced with several API price hikes in the past few weeks, we’re trying to make sure to continue bringing frontier AI to you at affordable price points. To that end, we’re introducing the batch API, available today on La Plateforme.

One Ministral, Many Ministraux

On the first anniversary of the release of Mistral 7B, the model that revolutionized independent frontier AI innovation for millions, we are proud to introduce two new state-of-the-art models for on-device computing and at-the-edge use cases. We call them les Ministraux: Ministral 3B and Ministral 8B.

Le Chat dives deep.

AI assistants are at their best when they let you go deeper in your thinking, keep your conversation flowing, and maintain contextual continuity. Today, we’re making Le Chat even more capable, more intuitive — and more fun — with a collection of powerful new features to help you research more thoroughly, express yourself more naturally, and keep your interactions — text, voice, and images — organized in context.

Mistral Moderation API

Safety plays a key role in making AI useful. At Mistral AI, we believe that system level guardrails are critical to protecting downstream deployments.That's why we are releasing a new content moderation API. It is the same API that powers the moderation service in Le Chat. We are launching it to empower our users to utilize and tailor this tool to their specific applications and safety standards.

Introducing Le Chat Enterprise

Today, we’re proud to introduce Le Chat Enterprise — a feature-rich AI assistant, powered by our brand new Mistral Medium 3 model. Solving enterprise AI challenges, like tool fragmentation, insecure knowledge integration, rigid models, and slow ROI, it delivers a unified AI platform for all organizational work.

Mistral Small 3.1

Today we announce Mistral Small 3.1: the best model in its weight class.

Devstral

Today we introduce Devstral, our agentic LLM for software engineering tasks. Devstral is built under a collaboration between Mistral AI and All Hands AI 🙌, and outperforms all open-source models on SWE-Bench Verified by a large margin. We release Devstral under the Apache 2.0 license.

Codestral Embed

We are excited to release Codestral Embed, our first embedding model specialized for code. It performs especially well for retrieval use cases on real-world code data.

Mistral Compute

Frontier AI. In Your Hands. This was the founding north star of Mistral AI and continues to guide our mission two years on. It has helped us evolve from a research lab to the world’s leading independent AI company, rooted in open science.

Introducing Mistral Code

Software engineering teams in enterprises can finally bring frontier-grade AI coding into their workflow in a secure, compliant manner. Mistral Code is an AI-powered coding assistant that bundles powerful models, an in-IDE assistant, local deployment options, and enterprise tooling into one fully supported package, so developers can 10X their productivity with the full backing of their IT and security teams.

Medium is the new large.

At Mistral AI, we are continuously pushing the frontier for both open models ( Mistral Small , Mistral Large, Pixtral, many others) as well as enterprise models ( Mistral OCR , Mistral Saba, Ministral 3B / 8B, and more). All the way from Mistral 7B , our models have consistently demonstrated performance of significantly higher-weight and more expensive models. And today, we are excited to announce Mistral Medium 3, pushing efficiency and usability of language models even further.
