yes but the assistant often doesn't search when it should and very rarely does multiple search rounds (both on gpt5 or on claude sonnet 4.5, weaker models are even worse at tool calling)
Cannot confirm this. Both sound like prompting issues.
- Depends on your use case to let the model understand when and when not to use tools
- gpt-5 s VERY persistent and often searches more than 10 times in a single run depending on the results.
We're using pydantic AI where the entire Agent loop is taken care of by the framework. Highly recommend.
