📝 Walkthrough

Summary by CodeRabbit

Documentation
- Updated LangChain integration examples to reference the newer Google Gemini model version.
- Standardized API endpoint parameter naming and updated proxy/local header snippets for consistency across Python and JavaScript examples.

Walkthrough

Documentation update to LangChain SDK integration examples: model references changed from gemini-1.5-flash to gemini-2.5-flash; Python examples rename endpoint argument google_api_base → base_url; JavaScript examples and local proxy snippets rename baseURL → baseUrl.

Changes

Cohort / File(s)	Summary
LangChain SDK docs `docs/integrations/langchain-sdk.mdx`	Updated all Google/Gemini examples to use `model="gemini-2.5-flash"`. Renamed endpoint/config parameters in code examples: Python `google_api_base` → `base_url`; JavaScript `baseURL` → `baseUrl`. Updated local "direct headers"/proxy snippet accordingly.

Poem

🐰 I hopped through docs with nimble paws,
Swapped flashes and fixed the endpoint clause.
"gemini-2.5" now leads the dance,
base_url and baseUrl in their stance.
A tiny hop, a tidy cause. ✨
