As a developer, I'd pay $100 a month for it if they allow 32k+ contexts. At least half my code is now generated from prompts.
This affects also GPTs personas. It starts out by following the instructions then gradually reverts to default GPT in the course of the conversation. Then when you ask why's that happening, it's like "oops, sorry, I'm totally <persona> now, see?" And then 5-6 messages later it forgets again.
