Mistral Launches Le Chat Enterprise with 256K Context and Tool Use

Mistral AI has announced a significant upgrade to Le Chat Enterprise, its business-oriented AI assistant platform. The update introduces a 256K context window, native tool calling capabilities, and a new Codestral 2.5 model aimed at enterprise software development teams.

What’s New

Extended Context (256K tokens): Le Chat Enterprise can now process entire codebases, legal documents, or technical manuals in a single prompt — roughly 200,000 words of context without truncation.

Native Tool Use: The platform now supports structured tool calling, enabling Le Chat to browse the web, execute code, query databases, and interact with enterprise APIs directly within a conversation.

Codestral 2.5: Mistral’s new code-focused model achieves 82.4% on HumanEval and reportedly outperforms GPT-4o on Python and Rust generation tasks according to internal benchmarks.

Pricing and Availability

Le Chat Enterprise is available immediately. Pricing starts at $30/user/month for teams under 50, with custom enterprise contracts for larger organizations. The API access for Codestral 2.5 is priced at $0.30 per million input tokens.

Why It Matters

Mistral has positioned itself as the European alternative to OpenAI and Anthropic, with an emphasis on data sovereignty (servers in the EU) and competitive pricing. The 256K context upgrade directly competes with Gemini 1.5 Pro and Claude 3.5 Sonnet’s long-context capabilities.
