+- OpenAI models now use the internal `self.get_key()` mechanism, which means they can be used from Python code in a way that will pick up keys that have been configured using `llm keys set` or the `OPENAI_API_KEY` environment variable. [#552](https://github.com/simonw/llm/issues/552). This code now works correctly:
+    ```python
+    import llm
+    print(llm.get_model("gpt-4o-mini").prompt("hi"))
+    ```
+- New documented API methods: `llm.get_default_model()`, `llm.set_default_model(alias)`, `llm.get_default_embedding_model(alias)`, `llm.set_default_embedding_model()`. [#553](https://github.com/simonw/llm/issues/553)
+- Support for OpenAI's new [o1 family](https://openai.com/o1/) of preview models, `llm -m o1-preview "prompt"` and `llm -m o1-mini "prompt"`. These models are currently only available to [tier 5](https://platform.openai.com/docs/guides/rate-limits/usage-tiers?context=tier-five) OpenAI API users, though this may change in the future.
