Medium is the new large. New model release from Mistral - this time closed source/proprietary. Mistral Medium claims strong benchmark scores similar to GPT-4o and Claude 3.7 Sonnet, but is priced at $0.40/million input and $2/million output - about the same price as GPT 4.1 Mini. For comparison, GPT-4o is $2.50/$10 and Claude 3.7 Sonnet is $3/$15.
The model is a vision LLM, accepting both images and text.
More interesting than the price is the deployment model. Mistral Medium may not be open weights but it is very much available for self-hosting:
Mistral Medium 3 can also be deployed on any cloud, including self-hosted environments of four GPUs and above.
Mistral's other announcement today is Le Chat Enterprise. This is a suite of tools that can integrate with your company's internal data and provide "agents" (these look similar to Claude Projects or OpenAI GPTs), again with the option to self-host.
Is there a new open weights model coming soon? This note tucked away at the bottom of the Mistral Medium 3 announcement seems to hint at that:
With the launches of Mistral Small in March and Mistral Medium today, it's no secret that we're working on something 'large' over the next few weeks. With even our medium-sized model being resoundingly better than flagship open source models such as Llama 4 Maverick, we're excited to 'open' up what's to come :)
I released llm-mistral 0.12 adding support for the new model.
