I got really lost on their site, but to help a bit according to their model page

devstral-2512 devstral-latest and devstral-medium-latest are all devstral 2 https://docs.mistral.ai/models/devstral-2-25-12

labs-devstral-small-2512 and devstral-small-latest are devstral small 2

devstral-medium-2507 is devstral 1.0

and devstral-small-2507 is devstral small 1.1

wow, thank you, this is great. I was thinking they should have a page like this, but I couldn't find myself.
