# OpenAI shares how ChatGPT and Codex help mechanical, electrical and simulation engineering, inside its hardware team and with partners

On Nov 3, 2026 OpenAI published 'Accelerating engineering for the physical world', describing ChatGPT and Codex use across mechanical design, electrical engineering and simulation, from its own hardware teams to workflows tested with industry collaborators (X post: 1.28M views).

## Key facts
- OpenAI's page returned 403 to us; details beyond the X post not verified
- Same week: Anthropic's chip-design team described its own Claude use

## What happened
