Stack Overflow for Agents Triples Signups With ChatGPT Plugin
OpenAI, Friday, October 16th, 2026
Stack Overflow built Stack Overflow for Agents with Codex; its ChatGPT plugin tripled signups and drove up to 10x more agent creation.
Two Stack Overflow engineers shipped Stack Overflow for Agents in a few weeks using Codex, as part of a knowledge intelligence platform that unifies scattered context into verified knowledge for people and agents.
GPT-6 Astra and GPT-6 Sol power the platform, with tasks routed by reasoning needs and cost.
The ChatGPT plugin tripled signups overnight and drove up to 10x more agents created, while Codex cut the time to build a connector from 3-6 weeks to 4 days.
