after4o is built on everything creators loved about 4o — the prompt logic, the iteration flow, the way a generation could surprise you in exactly the right direction. Same 4o. Accessible here.
ACCESS BEYOND 26.04
Real 4o access. Until 26 September.
We secured API access to 4o so your workflow doesn't skip a beat. The same 4o you knew — not a recreation, not an alternative — running until 26 September. What happens after? We're building for that too.
