## v0.2.0 (2026-07-20)



### Added



- **Streaming.** `ExAgent.chat_stream/3` (agent-level) and `ExAgent.Provider.stream/3`

  (provider-level) return a lazy `Stream` of text chunks. Tool-call turns are

  resolved non-streamed; only the final assistant turn is streamed. All three

  providers (OpenAI, Gemini, DeepSeek) implement the optional `stream/3` callback.

  Raises `ExAgent.StreamError` on non-200 responses / when the agent is busy.



### Changed



- **Providers are now a behaviour instead of protocols.** The `ExAgent.LlmProvider`

  and `ExAgent.FileUploader` protocols were removed and replaced by a single

  `ExAgent.Provider` behaviour (`chat/3` required, `upload/4` optional). Custom

  providers now declare `@behaviour ExAgent.Provider` and implement `chat/3`

  (and optionally `upload/4`) as public functions instead of using `defimpl`.

- **Non-blocking agent.** `ExAgent.Agent` now runs the tool loop off the GenServer

  (via a supervised task), so an agent stays responsive to reads (`get_context`)

  and casts while a request is in flight. A concurrent `chat/3` on a busy agent

  now returns `{:error, :busy}` instead of serializing behind the mailbox.



## v0.1.0 (2026-03-30)



First release!
