/// GPT-5.1 reasons on request and answers through both, GPT-5.5 reasons unless told not to.

/// The dot is what keeps the generations apart. A rule bound to the start of a name ends at a name

/// part, and a dot does not end one, so "gpt-5" does not answer for "gpt-5.1" -- which is exactly

|
|
/// output modality would have the chat offer to receive images which never arrive.
