OpenAI's Codex Spark, a faster Codex variant on Cerebras inference, enables real-time interactive coding and multi-agent workflows.

“Codex Spark is a lighter, faster version of Codex running on Cerebrus inference.”

OpenAI demoed Codex Spark, a lighter and faster version of Codex running on Cerebras inference, at Microsoft Build, showcasing interactive coding, multi-agent Slack/GitHub automations, and sub-second code reloads. The signal matters because low-latency inference keeps developers in flow state and makes agentic coding workflows practical, with OpenAI claiming model intelligence is now catching up to the already-high speed.
