llama.cpp serving tip: --reasoning-format none needed for agent/tool-call use

#1
by T0mSIlver - opened

Heads-up for anyone running these GGUFs with llama-server behind an agent harness: Fara emits an unclosed <think> tag, so default reasoning extraction puts the model's entire output (thoughts and the <tool_call> block) into reasoning_content, leaving message.content empty β€” harnesses that read content see an empty reply and fail.

Fix: serve with --reasoning-format none.
