OpenAI: prompt_cache_options is no longer accepted

OpenAI's published API specification no longer includes the prompt_cache_options field on CreateModelResponseProperties, affecting two OpenAI operations, according to an API-change report. The field is now ignored rather than rejected, so calls that still send prompt_cache_options succeed but behave differently, and the report advises developers to grep their code for the parameter. BetaCreateModelResponseProperties.prompt_cache_options was also removed.

What changed Usually ignored rather than rejected, so the call succeeds and does something subtly different. Affects prompt cache options on CreateModelResponseProperties reachable from 2 operations. Grep for it: nothing else will tell you. Who is affected Code that sends OpenAI's CreateModelResponseProperties objects, used by 2 OpenAI operations. Before and after | Where | Before | After | |---|---|---| | CreateModelResponseProperties.prompt cache options | present | absent | | BetaCreateModelResponseProperties.prompt cache options | present | absent | Code that breaks await client.post "/…", { // prompt cache options is now ignored, not rejected prompt cache options: value, } ; Based on OpenAI’s published API specification.
