Because Claude Code is stealing the thunder so OpenAI is focusing on coding now.

That is where the money is.

It's where the revenue is, but it isn't going to be where the profit is. Developers will easily use absurdly large amounts of compute, costing the AI provider a lot more than they receive in revenue.

We'll see. The first two things that they said would move from "emerging tech" to "currently exists" by April 2026 are: - "Someone you know has an AI boyfriend" - "Generalist agent AIs that can function as a personal secretary" I'd be curious how many people know someone that is sincerely in a relationship with an AI. And also I'd love to know anyone that has honestly replaced their human assistant / secretary with a…

> Someone you know has an AI boyfriend MyBoyfriendIsAI is a thing > Generalist agent AIs that can function as a personal secretary Isn't that what MoltBot/OpenClaw is all about? So far these look like successful predictions.

Moltbot is an attempt to do that. Would you hire it as a personal secretary and entrust all your personal data to it?

I want to recompile a Rust project to be f32 instead of f64. Am I better off buying 1 month of Codex, Claude, or Antigravity? I want to have the agent continuesly recompile and fix compile errors on loop until all the bugs from switching to f32 are gone.

Literally just find and replace

find and replace is step 1 that generates all the compile errors I want it to loop through

I'm wanting to do it on an entire programming language made in rust: https://github.com/uiua-lang/uiua

Because there are no float32 array languages in existence today

All of them can do it but Codex has the least frustrating usage limits.

When using it in VSCode? The browser system running its own container seems like it would be the most demanding on their resources. The stand-alone client is Mac-only but I don't know if it makes a difference.

My goal is to do it within the usage I get from a $20 monthly plan.

I think this announcement says a lot about OpenAI and their relationship to partners like Microsoft and NVIDIA, not to mention the attitude of their leadership team. On Microsoft Foundry I can see the new Codex 4.6 model right now , but GPT-5.3 is nowhere to be seen. I have a pre-paid account directly with OpenAI that has credits, but if I use that key with the Codex CLI, it can't access 5.3 either. The press release…

GPT 5.3 is not in the API yet AIUI.

I'm personally 100% convinced (assuming prices stay reasonable) that the Codex approach is here to stay. Having a human in the loop eliminates all the problems that LLMs have and continously reviewing small'ish chunks of code works really well from my experience. It saves so much time having Codex do all the plumbing so you can focus on the actual "core" part of a feature. LLMs still (and I doubt that changes) can't…

I'm personally 100% convinced of the opposite, that it's a waste of time to steer them. we know now that agentic loops can converge given the proper framing and self-reflectiveness tools.

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

I've been listening to the insane 100x productivity gains you all are getting with AI and "this new crazy model is a real game changer" for a few years now, I think it's about time I asked: Can you guys point me ton a single useful, majority LLM-written, preferably reliable, program that solves a non-trivial problem that hasn't been solved before a bunch of times in publicly available code?

the 100x gains, even 10x, are obviously ridiculous but that doesn't mean AI is useless

i like the opus 4.6 announcement a lot more, concise and to the point. for the 5.3 codex, it's a long post, but still, the most important info, the context window, is nowhere to be found. thus, I'm keeping using opus.

No, but Codex wouldn’t have asked you those questions either

I'm not sure if you'd call it a productivity gain, but I have to host our infrastructure on a system that runs processes entirely in Linux userland.

To bridge the containers in userland only, without root, I had to build: https://github.com/puzed/wrapguard

I'm sure it's not perfect, and I'm sure there are lots of performance/productivity gains that can be made, but it's allowed us to connect our CDN based containers (which don't have root) across multiple regions, talking to each other on the same Wireguard network.

No product existed that I could find to do this (at least none I could find), and I could never build this (within the timeframe) without the help of AI.
