Feature Drop: Mistral Medium 3.5

Mistral Medium 3.5 is now available on Omnifact. Mistral AI's flagship model tier brings a major upgrade in reasoning depth, agentic tool execution, and code generation for teams requiring high performance from an independent European provider.

Building on our original Mistral AI integration and our release of Mistral Nemo, Medium 3.5 updates our Mistral lineup for demanding professional work across chat, coding assistants, and document analysis in Spaces.

What Mistral Medium 3.5 Delivers

Mistral Medium 3.5 is designed for multi-step reasoning where reliability and precision matter. Key capabilities include:

• Agentic Coding and System Design: Generates, reviews, and refactors code with high precision. It handles multi-file projects, identifies architectural trade-offs, and plans implementation steps with minimal manual steering.
• Expanded 256k Context Window: Process extensive technical documentation, contract libraries, or lengthy conversation histories without losing critical details.
• Multimodal Input Support: Analyze diagrams, architecture charts, and technical documents alongside text prompts for unified visual and text analysis.
• European Hosting and Data Sovereignty: Hosted in the European Union by Paris-based Mistral AI, Medium 3.5 meets strict GDPR requirements without routing data through US hyperscaler infrastructure.

When to Choose Mistral Medium 3.5

Select Mistral Medium 3.5 when your team tackles complex tasks that demand sustained reasoning rather than simple lookups. It is well suited for:

• Refactoring codebases and authoring automated test suites.
• Synthesizing findings across dozens of sources in Spaces.
• Reviewing compliance policies and technical specifications.
• Organizations with strict data-residency policies requiring European AI infrastructure.

For routine high-volume tasks such as quick drafting or ticket classification, Mistral Small 4 offers a fast, budget-friendly alternative.
