Description
Hi,
When loading the gpt-oss 20b in Agent Builder, the tools section says "Tool not supported. The selected model doesn't support tools. Switch to a compatible model and try again." I'm on a Macbook Pro running Sequoia
When checking the Ollama model page (https://ollama.com/library/gpt-oss), gpt-oss is tagged as supporting tools.
