Check it is the real Devstral 2 123B, with your own key
The same battery we run before a route goes live: tokenizer fingerprint, knowledge cutoff, hidden-prompt probe and exact-output tasks, scored 0 to 100 against the vendor’s own API. One OpenRouter key verifies any text model; a direct Mistral Ai key works too. Exit code 0 means the same model.

- Is this the same Devstral 2 123B as calling Mistral Ai directly?
