Mistral AI Launches Medium 3: A Frontier Model with Multimodal Power and 8x Lower Cost

 Mistral AI has officially unveiled Mistral Medium 3, its latest multimodal AI model, designed to deliver state-of-the-art (SOTA) performance at a fraction of the cost. This new release is part of Mistral’s ongoing mission to combine cutting-edge AI capabilities with real-world deployability for enterprise use.

The Highlights

• A New Class of Models: Mistral Medium 3 strikes a balance between performance, cost, and ease of deployment—specifically tailored for enterprise environments.

• Multimodal & Coding-Ready: It excels in complex tasks like function-calling and code generation, and performs strongly on multimodal understanding.

• Enterprise-First Architecture: Designed for flexible deployment—on-premises, in VPCs, or hybrid setups. It also supports custom post-training and seamless integration with existing enterprise tools.

Benchmark Performance

Mistral Medium 3 doesn’t just promise—it delivers:

• 90%+ performance of Claude Sonnet 3.7, at significantly lower cost ($0.40 input / $2 output per million tokens)

• Outperforms open models like Llama 4 Maverick and even premium enterprise models such as Cohere Command R+

• Surpasses budget leaders like DeepSeek V3 in both API and self-hosted pricing

It can run efficiently on self-hosted environments with just four GPUs, making high performance accessible without massive infrastructure.

Human Evaluations & Real-World Use

Beyond synthetic benchmarks, human evaluations show that Mistral Medium 3 stands out—especially in STEM and coding tasks, where it competes with far larger and slower models. Real-world testing confirms its value across customer service, data analysis, and personalized enterprise workflows.

Built for Enterprise Integration

What sets Mistral Medium 3 apart is its full-stack enterprise readiness.
Organizations can:

• Continuously pretrain and fine-tune the model

• Plug it directly into internal knowledge systems

• Adapt it to domain-specific workflows

Early adopters in finance, healthcare, and energy are already leveraging the model to transform customer interactions and accelerate internal automation.

Available Now

Mistral Medium 3 is available via:

• Mistral La Plateforme

And One More Thing...

With Mistral Small launched in March and Medium now released, it's clear something large is coming soon. If Medium outperforms today’s open-source leaders, expectations are high for what Mistral has planned next.
