Frequently asked questions

Codex Mini can generate up to 100,000 tokens in a single response. Reasoning (thinking) tokens count toward this limit.
Codex Mini's training data runs through April 2024, so it may not know about later events. Coolhand records the cutoff at month precision, since providers often publish only the month.
