+## 0.62.1 - 2026-02-14

+This patch release focuses on updates to the AI Chat example.

+### Changed
+
+- Restored direct Gemini node usage across `examples/ai_chat` workflows instead of routing through provider abstractions.
+- Standardized Gemini model usage to `gemini-3-flash-preview` for text/schema generation and `gemini-2.5-flash-image` for image generation/editing flows.
+- Hardened Gemini schema request handling for empty/blocked responses and max-token edge cases.
+- Updated `examples/ai_chat/README.md` and backend `.env.example` so Gemini is the default path with Grok as an optional experimentation path.
