OpenAI Python 3.37.0 expands Decisions types
Live question instructions may now be either a string or structured text, image or JSON parts. Request types also accept more message roles and tool-history items. Existing strings remain supported, but code that applies string operations or exhaustively checks Decisions inputs must branch on the structured form before upgrading. 3
Relevant to: Python applications using Decisions or Live response models.
What the verdict meansWill break existing code: deprecation or API change.
