AI API receipt · BerriAI/litellm

Mistral content returned as a list of chunks is truncated to the last text chunk

BerriAI/litellm#45378 · upstream bug reproduced by running the issue's own reproduction

Badgr cannot tell this response is wrong

"The sky is blue during the day" + reference + "." arrived as ".".

"." is non-empty text; Badgr cannot know the rest of the answer is missing. If the caller supplies the expected value (text == "The sky is blue during the day."), Badgr rejects it: response text does not match the expected text. The receipt therefore records success. This is a limit of what the contract can prove, shown here so it is not mistaken for protection.

What the upstream returned (replayed)

The output the bug produces, taken from the issue’s reproduction and fed to Badgr’s validators. Not a live provider call.
