Potential Bug: Premature EOS and No Reasoning

#1
by nafishasan60 - opened

I'm seeing an issue with gemma-4-19b-a4b-it-REAP-i1-GGUF where some coding prompts result in an empty response.

The model processes normally, reaches 100%, and then returns:

"This message contains no content. The AI has nothing to say."

with the stop reason:

EOS Token Found

I've reproduced this multiple times with code-generation tasks (for example, generating a Python URL shortener script). Other models handle the same prompt without issues.

I've also noticed that the model doesn't seem to perform any visible reasoning/thinking before answering, even for prompts that typically trigger reasoning in other Gemma 4 variants.

Has anyone else reported this? Could it be related to the GGUF conversion, chat template, reasoning configuration, or premature EOS generation?

Screenshot attached. Thanks for taking a look.
