Multiple GPT-5 Variants Revealed in Deleted GitHub Post

OpenAI’s next-generation artificial intelligence model, GPT-5, has reportedly been leaked prior to its official release. According to reports, a now-deleted GitHub blog post briefly revealed several key details about the upcoming model lineup. The post included mentions of multiple GPT-5 variants: GPT-5 Base, GPT-5 Mini, GPT-5 Nano, and GPT-5 Chat, with an additional GPT-5 Pro version reportedly set to launch for premium subscribers.

The leak has sparked widespread interest across the tech community, especially as OpenAI prepares for a public livestream scheduled later this week.

Leak Origin and Key Takeaways

The information was first uncovered by TestingCatalog, which spotted the accidental blog post on GitHub. Although the post was quickly removed, users managed to capture screenshots and circulate them across social media platforms.

Based on the available details, OpenAI appears to be preparing a diverse lineup of GPT-5 models tailored to different use cases. The post did not include technical specifications, but each variant is expected to address unique performance and accessibility needs.

What We Know About the GPT-5 Variants

The base version of GPT-5 will likely serve as the default AI model accessible to most users. Alongside it, the GPT-5 Mini and GPT-5 Nano variants are expected to offer lightweight alternatives. While exact specifications remain unclear, the Mini version may prioritize faster response times, and Nano could be designed for on-device or edge computing deployments.

A new variant named GPT-5 Chat was also mentioned in the leaked post. This version is reportedly intended for enterprise use, particularly as part of GitHub Copilot, and will feature enhanced context awareness. According to a description cited by The Verge, GPT-5 Chat is “designed for advanced, natural, multimodal, and context-aware conversations for enterprise applications.”

Additionally, references to a potential GPT-5 Thinking variant suggest a future API tool that could allow developers to fine-tune how much computational effort or “thinking budget” the model uses. However, this variant remains speculative, with no official details confirmed.

Access Tiers: From Free to Pro

OpenAI reportedly plans to make GPT-5 accessible across different user tiers, each with varying levels of access and capabilities.

Free-tier users of ChatGPT are expected to receive basic access to GPT-5, albeit with rate limitations. ChatGPT Plus subscribers will reportedly enjoy GPT-5 with “advanced reasoning” capabilities and higher usage limits.

Pro users are said to gain access to GPT-5 Pro, a version described as offering “research-grade intelligence,” according to code-based leaks shared by X (formerly Twitter) user @scaling01. Meanwhile, ChatGPT Team subscribers are expected to access both GPT-5 with advanced reasoning and the Pro version, along with even greater usage flexibility.

ChatGPT Interface Set for Redesign

In addition to the model updates, OpenAI is said to be redesigning the ChatGPT user interface in conjunction with the GPT-5 release. According to TestingCatalog, the refreshed design will include a cleaner prompt bar, a consolidated action button to manage tasks and modes, and updated background colors for improved user experience.

The UI overhaul signals OpenAI’s broader push to streamline interactions and introduce a more polished feel to its flagship product.

Expectations High Ahead of Upcoming Livestream

Adding to the anticipation, OpenAI CEO Sam Altman recently announced an hour-long livestream scheduled for Thursday at 10 a.m. PDT (10:30 p.m. IST). In a post on X, Altman refrained from detailing what the presentation would include but highlighted that the length of the event is longer than usual for the company.

Industry watchers speculate that the livestream will serve as the platform for officially unveiling GPT-5 and possibly its associated updates, including the UI redesign and new subscription tiers.

OpenAI’s Broader Strategic Moves

The leak follows OpenAI’s recent decision to release its first open-source AI models since 2019, signaling a more transparent approach to development. While the GPT-5 models remain proprietary, the overall direction hints at increased customization and flexibility for enterprise and developer use cases.

With the AI race intensifying, OpenAI’s multi-tier rollout strategy for GPT-5 appears designed to cater to a wide range of users—from casual consumers to enterprise developers and academic researchers.
