OpenAI unveils GPT-5.5 'Spud' to boost autonomous multi-task AI
OpenAI released GPT-5.5, codenamed Spud, a faster, more capable model designed to handle messy, multi-step tasks with less prompting and better long-context reasoning, targeting coding, office work, and early scientific research. It’s available to paid ChatGPT and Codex users with API access coming soon, and Nvidia GPUs power the training, with plans to reduce per-token costs to help enterprise adoption in a compute-powered economy.
