Sam Altman Praises OpenAI’s Codex Team For Addressing Feedback As It Registers Strongest Daily Growth Since September Update

• Codex is a cloud-based software engineering agent that can work on many tasks in parallel.
• Initially launched in preview in May, Codex received a major update in September that was trained with a focus on real-world software engineering work.
• Codex is a major leap for OpenAI, with the company revealing at its DevDay event earlier in October that 92% of its engineers use the feature.

OpenAI co-founder and CEO Sam Altman praised the Codex team on Thursday for addressing user feedback regarding the latest major update.

“I love the way Tibo and team are so methodically going through every inch of the system to try to track down user feedback,” Altman said in a post on X, responding to a post by Codex lead Thibault “Tibo” Sottiaux.

While OpenAI is not listed, retail sentiment around the company on Stocktwits trended in the ‘neutral’ territory at the time of writing.

What Is Codex?

Codex is a cloud-based software engineering agent that can work on many tasks in parallel. Initially launched in preview in May, Codex received a major update in September that was trained with a focus on real-world software engineering work.

Following the update, Tibo noted in a post on X that Codex had its best day in terms of growth on Wednesday. “Codex had its strongest growth in one day yesterday since the launch of gpt-5-codex. Way to motivate the team during a gnarly investigation that's making us go through every piece of infra, hardware and line of code in our system,” Tibo said.

Why Is Codex Important?

Codex is a major leap for OpenAI, with the company revealing at its DevDay event earlier in October that 92% of its engineers use the feature, and that they also complete 70% more pull requests each week using the technology, according to a post by Greg Brockman, OpenAI’s co-founder and president.

Codex usage has also seen a tenfold increase since August, Altman said during the DevDay event, according to a report by ZDNET.

Earlier this week, OpenAI renewed its partnership with Microsoft Corp. (MSFT) as it transitioned to a public benefit corporation (PBC). The AI startup has reportedly initiated discussions about an initial public offering (IPO), with plans to raise $60 billion at a valuation of $1 trillion.
