'feel' is no more accurate not saying there's a better way but both suck

Speak for yourself. I've been insanely productive with Codex 5.2. With the right scaffolding these models are able to perform serious work at high quality levels.

..huh?

When 2 multi billion giants advertise same day, it is not competition but rather a sign of struggle and survival. With all the power of the "best artificial intelligence" at your disposition, and a lot of capital also all the brilliant minds, THIS IS WHAT YOU COULD COME UP WITH? Interesting

Yeah they are both fighting for survival. No surprise really. Need to keep the hype going if they are both IPO'ing later this year.

The AI market is an infinite sum market.

Consider the fact that 7 year old TPUs are still sitting at near 100p utilization today.

I think Anthropic rushed out the release before 10am this morning to avoid having to put in comparisons to GPT-5.3-codex! The new Opus 4.6 scores 65.4 on Terminal-Bench 2.0, up from 64.7 from GPT-5.2-codex. GPT-5.3-codex scores 77.3.

they tested it at xhigh reasoning though, which is probably double the cost of Anthropic's model.

Cost to Run Artificial Analysis Intelligence Index:

GPT-5.2 Codex (xhigh): $3244

Claude Opus 4.5-reasoning: $1485

(and probably similar values for the newer models?)

I'm having a hard time parsing the openai website.

Anyone know if it is possible to use this model with opencode with the plus subscription?

Something that caught my eye from the announcement: > GPT‑5.3‑Codex is our first model that was instrumental in creating itself. The Codex team used early versions to debug its own training I'm happy to see the Codex team moving to this kind of dogfooding. I think this was critical for Claude Code to achieve its momentum.

More importantly, this is the early steps of a model self improving itself. Do we still think we'll have soft take off?

Exponential growth may look like a very slow increase at first, but it's still exponential growth.

>There is no moat besides that. Compute. Google didn't announce $185 billion in capex to do cataloguing and flash cards.

Google didn't buy 30% of Anthropic to starve them of compute

Probably why it's selling them TPUs.

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…

I guess the jump is on purpose. You can buy Codex credits and also use codex via the API (manual switching required).
