Cerebras Big Chip Club: Ro Varma on Why Speed Changes What AI Agents Can Do
OpenAI reports 100% company Codex adoption, with 95% of non-engineering roles daily driving it
“Uh so 100% of the company is on codeex. um codecs has like become the daily driver for all engineering and I think like 95% of other roles are daily driving codecs.”
OpenAI Codex product lead Ro Varma reveals that 100% of OpenAI employees use Codex, with 95% of non-engineering roles using it as a daily driver — a rare data point on internal AI tool saturation at a frontier lab. The interview also surfaces Cerebras's pitch that its hardware enables 10x inference speed improvements at economically viable cost, which Varma frames as unlocking new agentic coding workflows. The combination of OpenAI's internal adoption numbers and the Cerebras speed-changes-what-agents-can-do thesis makes this a meaningful signal for enterprise AI adoption and agentic infrastructure trends.
