What I'm most confused, is why call it both GPT-5.3 Instant and gpt-5.3-chat?


instant kind of suck if you asking more than summerizations, surface info, web searches, it can lose track of who's who quickly in some complex multi turn asks. Just need to know what to use instant for.


Tbf there was a 5.3 codex
