Great discussion here—this highlights a real gap between the Chat Completions API and the newer Responses API. It’s clear the Responses API is the direction forward, especially with better multi-modal and tool-calling capabilities, but the lack of support in certain environments like Databricks makes adoption tricky.

The workaround using Chat Completions still works, but it feels like a temporary bridge rather than a long-term solution. Would be helpful if Databricks could share a clearer roadmap or timeline for full Responses API support so teams can plan migrations more confidently.

Curious if anyone has found a clean abstraction layer to switch between the two APIs without major refactoring?
