I am on a max subscription for Claude, and hate the fact that OpenAI have not figured out that $20 => $200 is a big jump. Good luck to them. In terms of model, just last night, Codex 5.2 solved a problem for me which other models were going round and round. Almost same instructions. That said, I still plan to be on $100 Claude (overall value across many tasks, ability to create docs, co-work), and may bump up OpenAI subscription to the next tier should they decide to introduce one. Not going to $200 even with 5.3, unless my company pays for it.

I'd like to know if and how much illegal use of customer prompts are used for training.

According to Sam Altman, Anthropic is for "rich people." Judging by his $4 million man-baby Koeniggsegg, he must be a huge Claude Code user!

Does it insert adverts in your code?

what are the benchmarks against opus 4.6?

Whoa, I think GPT-5.2-Codex was a disappointment, but GPT-5.3-Codex is definitely the future!

Anybody else not seeing it available in Codex app or CLI yet (with Plus)?

Anthropic and GTP 2 new models at once?

Pelican seems much worse than the Opus 4.6 one (though the bicycle is more accurate):

It is absurd to release 5.3-Codex before first releasing 5.3.

Also, there is no reason for OpenAI and Anthropic to be trying to one-up each other's releases on the same day. It is hell for the reader.

Almost like Anthropic and OpenAI are trying to front run each other

I know we just got a reset and a 2× bump with the native app release, but shipping 5.3 with no reset feels mismatched. If I’d known this was coming, I wouldn’t have used up the quota on the previous model.

Is this me or Sam is being absolute sore loser he is and trying to steal Opus thunder?
