@@ -153,7 +153,7 @@ When using `--json`, the agent outputs these event types:
 **Note:**
 - OpenAI's Chat Completions API (`--api completions`, the default) only returns reasoning token *counts* but not the actual thinking content. To see thinking events, use the Responses API with `--api responses` for supported models (o1, o3, gpt-5).
 - Anthropic's OpenAI compatibility layer doesn't return thinking content. Use the native Anthropic API for full extended thinking features.
-- Gemini 2.5 models support reasoning via `reasoning_effort` but require the `extra_body` parameter with `thinking_config.include_thoughts: true` to get thinking content, which is not yet supported in pi-agent.
+- Gemini 2.5 models automatically include thinking content when reasoning is detected - pi-agent handles the `extra_body` configuration for you.
 
 The complete TypeScript type definition for `AgentEvent` can be found in [`src/agent.ts`](src/agent.ts#L6).
