OpenAI’s GPT-5 Models Leaked on GitHub

OpenAI’s upcoming artificial intelligence model, GPT-5, has reportedly been leaked through a now-deleted GitHub blog post. The leak, first identified by TestingCatalog, revealed details about several variants of the GPT-5 model. These include the base model, GPT-5 Mini, GPT-5 Nano, and a new GPT-5 Chat designed for enterprise use. Additionally, a GPT-5 Pro model is expected to be available for Pro subscribers. The leak has generated significant interest and speculation within the tech community.

Variants and Features of GPT-5

The leaked information suggests that OpenAI plans to release four main variants of the GPT-5 model. The base variant will be accompanied by Mini and Nano versions. Although specific details about these variants are scarce, it is speculated that the Mini version may offer faster response times, while the Nano variant could be optimized for edge computing and local deployments. Furthermore, references to a GPT-5 Thinking API have surfaced, hinting at potential developer tools for customizing the model’s processing capabilities.

Enterprise-Focused GPT-5 Chat

The GPT-5 Chat variant is reportedly designed to enhance GitHub Copilot’s functionality by providing more context-aware interactions. According to The Verge, this variant aims to support advanced, natural, multimodal conversations tailored for enterprise applications. This development could significantly improve collaborative coding and project management tasks within organizations.

Access and Pricing Details

Access to the new models will reportedly be tiered. Users on ChatGPT’s free tier will receive basic access to GPT-5, while Plus subscribers will enjoy advanced reasoning capabilities with higher usage limits. Pro subscribers are expected to gain access to the GPT-5 Pro model, which promises enhanced computational power for complex queries. A separate leak suggests that the Pro variant may offer “research-grade intelligence,” although its practical applications remain unclear.

Anticipated Redesign and Livestream Announcement

In addition to the new models, ChatGPT is set to undergo a user interface redesign. The updated interface will feature a streamlined prompt bar, consolidated action buttons, and refreshed background colors. OpenAI CEO Sam Altman has announced an upcoming livestream event where further details about these developments are expected to be unveiled. The livestream is scheduled for Thursday at 10 am PDT (10:30 pm IST), sparking anticipation for potential announcements regarding GPT-5’s official release.
