# NousResearch/hermes-agent · Gemini 3 thinking config: thinkingBudget vs thinkingLevel handling

## Open now

- Nothing open on GitHub.

These members all concern how reasoning/thinking is disabled for Gemini 3 and later models, covering the deprecated thinkingBudget: 0 setting and use of thinkingLevel or version-gated logic instead. One also mentions bounded long decode, which goes beyond the shared theme.
