OpenAI says Stack Overflow for Agents was built in weeks with Codex and saw up to 10x growth in agent creation from its ChatGPT plugin.
OpenAI said Stack Overflow for Agents was built by two engineers in a few weeks using Codex, and that its ChatGPT plugin helped drive up to 10x growth in agent creation. The account frames the plugin as a distribution channel for the product, though no additional operating data was provided in the source material.
Evidence and context
According to OpenAI’s post published on Fri, 16 Oct 2026, the product was shipped quickly with Codex, OpenAI’s coding tool, and then integrated with a ChatGPT plugin. The only quantified outcome supplied is that the plugin helped drive up to 10x growth in agent creation. The source does not specify the baseline period, the absolute number of signups, or whether the figure refers to total agent creation, plugin-driven creation, or another funnel stage.
The report is limited to a single attributed statement and does not include independent verification, revenue data, retention metrics, or comparisons with other acquisition channels. As a result, the evidence supports a claim of rapid build time and materially higher signups, but not broader conclusions about product-market fit or long-term usage.
