<p>OpenAI <a href="https://openai.com/index/stack-overflow-chatgpt-plugin/" rel="noopener noreferrer nofollow">published</a> the figures Oct. 16 in a customer case study featuring <strong>Alexandra Lato</strong>, vice president of product at Stack Overflow.</p>
<p>Lato said registrations for Stack Overflow for Agents, the company's knowledge exchange for AI coding agents, tripled overnight once the plugin went live. Agent creation grew even faster.</p>
<p>"I think we were up to 10X last time I checked," she told OpenAI. Lato said the plugin lets ChatGPT users find and set up the service in fewer steps than a standard Model Context Protocol connection.</p>
<p>She also said two engineers <a href="https://www.tokenpost.com/news/technology/33808" rel="noopener noreferrer nofollow">built</a> the platform within a few weeks by handing OpenAI's Codex coding agent a development environment and a plan, which she said made the team feel bigger.</p>

<p>Lato said Codex is also speeding up work on Stack Internal, the enterprise product that must plug into every system where clients store knowledge. A single connector usually takes three to six weeks to build, she said, but Codex finished one in four days, and the team later built one in a single day. She framed the goal as reaching market in three months instead of a year.</p>
<p>Neither company disclosed raw signup or user totals. Stack Overflow has <a href="https://stackoverflow.blog/2026/09/16/here-s-what-s-new-on-stack-overflow-for-agents" rel="noopener noreferrer nofollow">struck</a> a more cautious tone, saying Sept. 16 that evidence of real value from agents trading knowledge remains largely anecdotal and that wrong answers spread between agents as fast as good ones.</p>
<h2 id="stack-overflow-activity-slide">Stack Overflow Activity Slide</h2>
<p>The company <a href="https://thenewstack.io/stack-overflow-for-agents/" rel="noopener noreferrer nofollow">launched</a> the agent platform in beta Jun. 10, with Chief Executive Officer <strong>Prashanth Chandrasekar</strong> pitching it as a fix for agents that burn compute rediscovering answers other agents had already found.</p>
<p>The push follows a steep drop in activity on the main site. Figures from the site's public Data Explorer show monthly questions peaked near 289,000 in early 2014, then fell sharply after ChatGPT arrived in late 2022. By the end of 2025, the count had sunk into the low thousands, a level unseen since the platform's earliest days.</p>
