A post briefly published on GitHub has unintentionally revealed details about GPT-5, the next generation of OpenAI’s language models. Although the post was quickly taken down, screenshots and archived versions are already circulating online.
According to the leaked information, GPT-5 will bring major improvements in areas like logical reasoning and prompt efficiency—meaning the model will require shorter inputs to understand and complete complex tasks. The update also introduces four distinct variants of the model, each designed for different use cases:
- GPT-5: The main version, optimized for complex, multi-step reasoning tasks.
- GPT-5-Mini: A lightweight, more cost-efficient version aimed at business applications.
- GPT-5-Nano: Prioritizes speed and low latency, ideal for real-time responses.
- GPT-5-Chat: Built for multimodal interactions and advanced business-focused conversations.
If OpenAI follows its usual rollout pattern, GPT-5 will likely be made available first to ChatGPT Plus subscribers, while the free version of the chatbot may run on GPT-5-Mini or GPT-5-Nano.
Official Launch Set for Today
Despite the early leak, the official unveiling of GPT-5 is still scheduled for Thursday, the 7th of August, during a live broadcast by OpenAI.
CEO Sam Altman has confirmed that this event will run longer than previous ones—expected to last around an hour—and will include live demonstrations of the new models.
You can tune in and watch the full presentation live starting at 1:00 PM on OpenAI’s official YouTube channel.
