Title: Medium is the new large
Feedly Summary: 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.
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 🙂
