mistral-7b-instruct-v0.1 cannot accept tokens

I found a bug. Using the @cf/mistral/mistral-7b-instruct-v0.1 model, if you use messages to chat, max_tokens does not take effect. The default value of cloudflare is 256 toekns. I actually configured 1500 tokens, but the total It ends after generating about 200 tokens. There is no way to break the length using prompt words, so it should be an official bug limit, and tokens are not passed correctly.
The API endpoint I’m using is https://api.cloudflare.com/client/v4/accounts/xxxx/ai/run/@cf/mistral/mistral-7b-instruct-v0.1

hi?Can anyone answer this question?
