Mistral 3 on Microsoft Foundry: Open, multimodal, enterprise-ready

Explore Mistral Large 3 in Azure—open-source, long-context, multimodal AI built for reliable enterprise workloads.

Enterprises today are embracing open-weight models for their transparency, flexibility, and ability to run across a broad range of deployment architectures. As the number of open models grows, the bar for reliability, instruction-following quality, multimodal reasoning, and long-context performance continues to rise. 

Today, we’re excited to announce that Mistral Large 3 is now available in Azure, bringing one of the strongest open-weight, Apache-licensed frontier models to the Microsoft Cloud. 

Mistral Large 3 delivers frontier-class capabilities with open-source flexibility, making it a powerful option for organizations building production assistants, retrieval-augmented applications, agentic systems, and multimodal workflows. 

Enterprise-ready open models 

Mistral Large 3 sits in the leading tier of globally available open models alongside DeepSeek and the GPT OSS family. It is optimized not only for benchmark-chasing on abstract mathematical puzzles, but also for what customers need most in real enterprise applications: 

• Highly reliable instruction following 
• Long-context comprehension and retention 
• Strong multimodal reasoning 
• Stable, predictable performance across dialogue and applied reasoning 

According to Mistral, Mistral Large 3 shows fewer breakdowns and more consistent behavior than most peers, especially in multi-turn conversations and complex, extended inputs. It is designed for production, not just experimentation. 

Mistral 3 is optimized for real-world scenarios 

Instruction reliability you can depend on 

Many open models excel on benchmarks but struggle with instruction clarity when deployed in real workflows. Mistral Large 3 reverses that trend by demonstrating:

• Precise adherence to task instructions 
• Strong grounding in domain knowledge 
• Low hallucination rates
• Consistent formatting in structured outputs 

This makes it particularly effective for agents, automation flows, and business logic integration where reliability is non-negotiable. 

Exceptional long-context handling 

With extended context support, Mistral Large 3 processes, retains, and reasons over long documents, multi-step sequences, and sustained dialogues with notable stability. 

Enterprises can use it for: 

• Retrieval-augmented generation 
• Document understanding 
• Multi-turn conversational systems 
• Long-form summarization and synthesis 

Its ability to maintain coherence over long sessions reduces error cascades and produces more predictable outcomes. 

Multimodal and applied reasoning 

As organizations build increasingly multimodal workflows, interpreting text, images, diagrams, and structured data, Mistral Large 3 provides strong cross-modal understanding with balanced behavior. 

It excels in: 

• Visual question answering 
• Diagram or chart interpretation 
• Multimodal retrieval and grounding 
• Combined reasoning over text and image inputs 

Its stability makes it ideal for use cases where multimodal reasoning must be accurate, not approximate. 

Fully Open and Apache 2.0 licensed

Mistral Large 3 stands out as the strongest fully open model developed outside of China and offers something rare in the global ecosystem: 

Frontier-level capability, Apache 2.0 licensing, reproducible results, and worldwide availability without regional restrictions. 

Organizations can: 

• Integrate the model in Microsoft Foundry 
• Export weights for hybrid or on-premises deployment (subject to Mistral licensing) 
• Run it in their own VPC, edge, or sovereign cloud environments 
• Fine-tune or customize freely 
• Use it for commercial applications without attribution requirements 

This combination of capability and openness is uniquely compelling for global enterprises requiring flexibility, transparency, and long-term vendor independence.
