Why does OpenAI have a separate model for coding (Codex) but Anthropic uses the same model for chatbots and coding?

They seem to be slowly moving away from having a separate coding model. With this release, they're calling the model Codex but expressly mention that it's also supposed to be more suitable than GPT 5.2 for general use.

> With Codex (5.3), the framing is an interactive collaborator: you steer it mid-execution, stay in the loop, course-correct as it works. > With Opus 4.6, the emphasis is the opposite: a more autonomous, agentic, thoughtful system that plans deeply, runs longer, and asks less of the human. Ain't the UX is the exact opposite? Codex thinks much longer before gives you back the answer.

I've also had the exact opposite experience with tone. Claude Code wants to build with me, and Codex wants to go off on its own for a while before returning with opinions.

Same here, CC gives me options to pick direction after the planning stage.

Define "losing." Europe is prematurely regarded as having lost the AI race. And yet a large portion of Europe live higher quality lives compared to their American counterparts, live longer, and don't have to worry about an elected orange unleashing brutality on them.

Europe has already lost the tech race - their cloud systems that their entire welfare states rely upon are all hosted on servers hosted by American private companies, which can turn them off with a flick of a switch if and when needed. When the welfare state, enabled by technology, falls apart, it won't take long for European society to fall apart. Except France maybe.

welfare state enabled by cloud services/technology?

I'm not sure if you know less about europe or tech.

> Except France maybe.

sure

Where did they say that?

Where did they say that?

"The model advances both the frontier coding performance of GPT‑5.2-Codex and the reasoning and professional knowledge capabilities of GPT‑5.2, together in one model, which is also 25% faster. ... With GPT‑5.3-Codex, Codex goes from an agent that can write and review code to an agent that can do nearly anything developers and professionals can do on a computer."

They're specifically saying that they're planning for an overall improvement over the general-purpose GPT 5.2.

For me, it still asks for confirmation at every decision when using plans. And when multiple unforeseen options appear, it asks again. I don’t think you’ve used Codex in a while.

It asks you what your coworkers are working on and whether the thing you are working on are your boss’ number one priority?

Does the AI agent know what your company is doing right now, what every coworker is working on, how they are doing it, and how your boss will change priorities next month without being told? If it really knows better, then fire everyone and let the agent take charge. lol

A significant portion of engineering time is now spent ensuring that yes, the LLM does know about all of that. This context can be surfaced through skills, MCP, connectors, RAG over your tools, etc. Companies are also starting to reshape their entire processes to ensure this information can be properly and accurately surfaced. Most are still far from completing that transformation, but progress tends to happen slowly…

Unless you're retiring in less than 5 years this is extremely short sighted.

What would things look like to make someone with currently ~10 years of experience unemployable? It's possible the job might change drastically, but I'm struggling to think of any scenario that doesn't also put most white collar professions out of work alongside me, and I don't think that's worth worrying about

> I'm struggling to think of any scenario that doesn't also put most white collar professions out of work alongside me

You don't need to be out of a job to struggle. Just for your pay to remain the same (or lower), for your work conditions to degrade (you think jQuery spaguetti was a mess? good luck with AI spaguetti slop) or for competition to increase because now most of the devving involves tedious fixing of AI code and the actual programming heavy jobs are as fought for as dev roles at Google/Jane Street/etc.

Devving isn't going anywhere but just like you don't punch cards anymore, you shouldn't expect your role in the coming decades to be the same as the 90s-25s period.

This has already been going on for years. It's just that they were using GPT 4.5 to work on GPT 5. All this announcement mean is that they're confident enough in early GPT 5.3 model output to further refine GPT 5.3 based on initial 5.3. But yes, takeoff will still happen because of this recursive self improvement works, it's just that we're already past the inception point.

I can't tell if this is a serious conversation anymore.

I totally got what you felt there. We are truly living in a sci-fi world
