GGUF Model Long Context Infinite Thinking
Both the GGUF I converted and other community-converted versions of Step Flash 3.7 GGUF suffer from an infinite thinking issue with long contexts — not repetitive responses, but endless reasoning that never concludes. Only the officially released GGUF works correctly.
The performance of the GGUF model has also degraded significantly. For example, when my input contains the word "strategy", the model incorrectly claims there is a spelling error and treats it as "strateg".
It's unclear whether this is an issue with the model itself.
Also see https://huggingface.co/unsloth/Step-3.7-Flash-GGUF/discussions/1#6a1a84c7ac67b51dd73e9ffe
The 'strategies' in the code was recognized as 'strategٹ' — probably a model issue.
The official IQ4_XS has this issue too......
