There's no conclusive evidence that this is the exact mistral-medium leak, however a lot of people tried it and confirmed that outputs are very close to the ones that mistral-medium gives through the API, sometimes an exact match. You can search for either "miqu" or "mistral medium" on Twitter to find that info.
