- In le Chat, we added a mitigation against an obfuscated prompt method that could lead to data exfiltration, reported by researchers Xiaohan Fu and Earlence Fernandes. The attack required users to willingfully copy and paste adversarial prompts and provide personal data to the model. No user was impacted and no data was exfiltrated.
- OCR 4.1 ( mistral-ocr-4-1 ) is now Generally Available.
- Added a new parameter p to the chunks streamed back by the Completion API. Implemented for security to prevent token-length side-channel attacks, as reported by Microsoft researchers. Note that this change may break applications relying on strict parsing of the chunks. Applications using the official SDK are unaffected, but users relying on the mistral-common package may need to update to 1.8.4 or higher.

The endpoint mistral-small will be deprecated in three months. mistral-small-latest (aka mistral-small-2402 ): new model. mistral-medium-latest (aka mistral-medium-2312 ): old model. The previous mistral-medium has been dated and tagged as mistral-medium-2312 . The endpoint mistral-medium will be deprecated in three months. mistral-large-latest (aka mistral-large-2402 ): our new flagship model with leading performance. - New API capabilities: Function calling : available for Mistral Small and Mistral Large.

If you have unsupported parameters in your request, you will see the error message "Extra inputs are not permitted". - A previous version of the guardrailing documentation incorrectly referred to the API parameter as safe_mode instead of safe_prompt . We corrected this in the documentation.
