How would you prefer us to charge for Codex? ...

The 5.3 lovefest is so nice to see.Don't think we've had so much excitement for a model since the original GPT-4. ...

RT Ben Davis (@davis7)GPT-5.3 Codex is a massive improvement over 5.2 holy shitWay faster, fewer tool calls, and a more accurate result... https://t.co/98VXbA8SSD ...

appreciate this, but what an aesthetic mess(nice that it's mathematically accurate i guess)Theo - t3.gg (@theo):5.3 > 4.6 > 3 ...

RT Trevor Cai (@trevorycai)3 years ago, we emailed Jensen with requests for Blackwell. Today, we released GPT-5.3-Codex, a SOTA model designed for GB200-NVL72. Nitpicking ISA, simming rack designs, and tailoring our arch to the system has been a fun experience! I'm grateful to our collaborators at NVIDIA. https://t.co/ZIv57Bdh9A ...

This is our first model that hits "high" for cybersecurity on our preparedness framework.We are piloting a Trusted Access framework, and committing $10 million in API credits to accelerate cyber defense.https://t.co/vN8KpIuzjt ...

It was amazing to watch how much faster we were able to ship 5.3-Codex by using 5.3-Codex, and fore sure this is a sign of things to come. ...

I love building with this model; it feels like more of a step forward than the benchmarks suggest.Also you can choose "pragmatic" or "friendly" for its personality; people have strong preferences one way or the other!Sam Altman (@sama):GPT-5.3-Codex is here!*Best coding performance (57% SWE-Bench Pro, 76% TerminalBench 2.0, 64% OSWorld).*Mid-task steerability and live updates during tasks.*Faster! Less than half the tokens of 5.2-Codex for same tasks, and >25% faster per token!*Good computer use. ...

Big drop for Codex users later today!You can just build things. ...
