    Pro tip: for long multi-hour tasks, many of us at @OpenAI start by asking codex to write a markdown file with a plan and todos. Iterate on the plan then go!

    Demand for GPT-5-Codex is higher than forecasted and we need to stand up more GPUs! In the meantime Codex is running 2x slower than targets. Working on fixing this ASAP

    Knowledge cutoff banished! Now ChatGPT has access to real time information. Big by itself. Magical as we start combining it with all the other capabilities we're building.

    We just reset Codex rate limits for everyone, and refunded all Codex credit usage up until 1p PT Friday. Enjoy! Why: On Thursday we rolled out credits to give users options between our $20 and $200 plans. However we had a bug where we overcharged for cloud task usage by ~2-5x
