# NousResearch/hermes-agent · Gemini 3.x thinking configuration handling in adapters

## Open now

- Nothing open on GitHub.

The members all concern how thinking settings are sent to Gemini 3.x models, including Flash-Lite. One issue reports a 400 response when thinkingBudget: 0 is sent, and two pull requests propose changes such as using a minimal thinking level and version-gating thinking behavior. One also mentions bounding long decodes.
