* **Tool calling with `#[tool]`**:
  Define callable functions with structured inputs/outputs.

* **Streaming + Tool progress events**:
  Stream model responses while tracking tool execution in real time.

* **Axum SSE integration**:
  Use `AxumSseResponse` for clean state handling and streaming responses.

* **React + [Vercel AI SDK](https://ai-sdk.dev/docs/ai-sdk-ui/chatbot) (`useChat`)**
  Text + ToolCall Streaming with seamless frontend integration.
