OpenAI Hints at "gpt-5-thinking" Model via 404 Page Easter Egg
Executive Summary
OpenAI appears to have subtly teased its next-generation AI model on a 404 "Not Found" error page on its website. The page features a short, poetic phrase which is then attributed to a system named "gpt-5-thinking." This is not a formal product announcement but is being widely interpreted as an intentional "easter egg" designed to hint at the successor to GPT-4 and generate industry speculation.
Key Takeaways
* Implied Name: The text explicitly mentions "gpt-5-thinking," suggesting a potential name or internal codename for OpenAI's next major model.
* Unconventional Teaser: The information was not released via a press release or blog post, but was discovered as creative copy on a technical error page.
* No Official Details: The page provides no information about the model's capabilities, features, pricing, or potential release date.
* Content: The only output attributed to the model is a three-line poetic phrase: "Portal out of sight / Edges glimmer, faint but sure / Carry light and go".
Strategic Importance
This subtle teaser strategy allows OpenAI to generate significant market anticipation and media buzz for its next flagship model without committing to a formal announcement or timeline. It effectively keeps the company at the center of the AI conversation while maintaining full control over the official product reveal.
