The change in endpoint name is a strong suggestion that there will be few if any open models going forwards from mistral. It’s a clear move towards the default being closed. Disappointing but I guess unsurprising.
From deeper in the page, unclear whether this confirms your point:
We’re simplifying our endpoint offering to provide the following:
- Open-weight endpoints with competitive pricing. This comprises open-mistral-7B and open-mixtral-8x7b.
- New optimised model endpoints, mistral-small-2402 and mistral-large-2402. We’re maintaining mistral-medium, which we are not updating today.
I don't think the naming really suggests that. The new naming suggests they'll have two sets, the "open" models and their commercial ones.
I do agree with your skepticism though. I kinda expected them to release something, likely an older model. Currently the closest is "miqu" which was a leak of a early quantized "medium".
