OpenAI’s new GPT-5 models announced early by GitHub
GitHub briefly posted (and then deleted) a blog revealing OpenAI’s GPT-5 lineup: gpt-5 for logic and multi-step tasks, gpt-5-mini for cost-sensitive use, gpt-5-nano for low-latency speed, and gpt-5-chat for advanced multimodal enterprise conversations. The leak touted major gains in reasoning, code quality, and agentic abilities. OpenAI will officially unveil GPT-5 today with a 10AM PT livestream, following this week’s release of new GPT-OSS open-weight models.
