pub const RESPONSES_PATH: &str = "/v1/responses";Expand description
Where Codex sends its conversation: OpenAI’s Responses shape, the only one Codex still speaks
to a provider of one’s own (its 0.156.1 program answers wire_api = "chat" with “is no longer
supported”). It is a conversation in the OpenAI shape like the completion path, so it goes to
the same root.
