I don't think it can be an operation name - there are several operations in responses API:

I think a path forward might be an openai specific attribute that records an API type/version

[singankit]

My opinion is that chat completion and responses have very similar operations. Reponses Migration guide also talks about the similarity of features between the two.

If chat-completion is available as an operation in Gen AI Sem Conv can responses be an operation too ?

I don't think responses should be added in this way. It's the name of one implementation/protocol of a "chat" API. Each provider has one or more. From my perspective, the operation should continue being chat, and if the name of the endpoint needs to be tracked, it can be done in a separate tag.
