👐Use gpt-oss with `deepagents`
Deep Agents require good tool calling capabilities... something that OpenAI's new open source model is pretty good at
Thanks to Ryan Eggleston for adding an example how to use gpt-oss (via ollama) to `deepagents`

✏️ How to Create a RAG Agent with Reflection
🔍 RAG is a powerful technique that supplies your agent with external information, and can improve agent performance. However, relying on RAG alone, agents can often pull in irrelevant documents to the user question.
