Two OpenAI team members worked with GPT-6 Astra to design a prototype device for talking to Codex in under a week, as a side project. Astra designed the enclosure, circuit board, interface, and software. Getting it manufactured still required several rounds of review and iteration.

We’re also working with engineers at Chip Ganassi Racing to turn 3D scans into editable CAD models and manufacturing drawings, and with Mazda to explore new vehicle designs through simulation. Engineers review the outputs and help identify where the models need to improve.

These are early steps, and we’re looking for engineers, engineering firms, and software partners to help shape what comes next. openai.com/index/acceleratin…

Physical design loops are compute heavy. Faster iteration still means more GPU hours on the back end.

No one can used anything in your Ai. So cool that those with business ties to you can use AI for science. Congratulations Stanford. Why let children learn when you can force everyone to be beholden to gatekeepers? •

what is Codex actually producing for mechanical design? CAD scripts, parametric models, or reviews of files engineers already made? each one is a very different workflow.

Iteration speed is easy. Sign-off is slow. 🧐

Exciting, but physical engineering is less forgiving than code. A wrong line of software gets a patch. A wrong tolerance gets a recall. Who signs off on the design?

pcb design is one thing, getting it through manufacturing is another

Faster hardware iteration could shorten product cycles more than most teams expect.

hardware engineers burning 23x more tokens since feb. that's the revenue line nobody's modeling

I've got a growing list of ideas that need screws instead of another browser tab.

when does the agent get its own test bench

Where has Codex helped your hardware teams most so far: mechanical design, electrical engineering or simulation? And where does it still need an engineer close by?

WHERE IS 6.2!?

I bet Astra 6.2 would be incredible at this type of stuff...

I was able to design this product with Astra (enclosing and PCB). That's crazy to see what can be done with AI kow

I'm currently an undergrad in mechatronics and I've been using GPT-6 Astra and Codex a lot. You can really see both the progress and the bottlenecks. These models let me get so much done in way less time now I don't have to waste hours hunting for component datasheets and reading through them anymore. Hardware still feels pretty limited though.

You cant even use 6.1 light on codex without it draining all of your usage now. I ran one task today and my entire 5 hour was gone in 20 mins on fucking light!

Yup! @OpenAI Check out my Codex built PCB and it also ordered the parts for it, i only approved the spend!

does it do tolerance stack-ups too? asking for every mech engineer

Codex for hardware: where "works on my machine" finally refers to an actual machine.

Prototype device in under a week with Codex. Lovely. Now get it to build a time machine so UK users get features the same day as the US.

@grok has OpenAI stopped updating their official Codex extension for VSCode? marketplace.visualstudio.com…
