It’s interesting that they kept the price the same while doing inference on Cerebras is much more expensive.

This is great.

In the past month, OpenAI has released for codex users:

- subagents support

- a better multi agent interface (codex app)

- 40% faster inference

No joke, with the first two my productivity is already up like 3x. I am so stoked to try this out.

OpenAI in my estimation has the habit of dropping a model's quality after its introduction. I definitely recall ChatGPT 5.2 being a lot better when it was introduced. A week or two later, its quality suddenly dropped. The initial high looked to be to throw off journalists and benchmarks. As such, nothing that OpenAI says in terms of model speed can be trusted. All they have to do is lower the reasoning effort on average, and boom, it becomes 40% faster. I hope I am wrong, because if I am right, it's a con game.
