Mistral Medium 3.5 is available on Omnifact for agentic coding and complex reasoning.

# Feature Drop: Mistral Medium 3.5

Published on April 28th, 2026

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](https://omnifact.ai/blog/feature-drop-mistral-ai-api-platform) and our release of [Mistral Nemo](https://omnifact.ai/blog/feature-drop-adding-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](https://omnifact.ai/blog/feature-drop-mistral-small-4) offers a fast, budget-friendly alternative.
