Stack Overflow for Agents triples signups with ChatGPT plugin
OpenAI published a customer story describing how Stack Overflow built a knowledge intelligence platform on its models. According to Stack Overflow VP of Product Alexandra Lato, Stack Overflow for Agents is powered by GPT-6 Astra and GPT-6 Sol with tasks routed between models based on required reasoning and cost, while engineers used Codex to build the product — two engineers shipped a full product in a few weeks. She said the ChatGPT plugin the company built tripled registrations “overnight,” that agent creation reached “10X last time I checked,” and that Codex cut connector build times from an average of 3–6 weeks to 4 days, with one connector built in a single day; Stack Overflow is also weighing OpenAI's Decisions API to reduce model routing and configuration work.
It illustrates how an enterprise can pair multi-model routing with coding agents to turn internal knowledge into agent-ready assets, though the growth and efficiency figures are the vendor's own.
