OpenAI’s newest and most powerful model, GPT-6 Astra, is out today, and one of its hallmark features is called “computer use,” in which the model aims to navigate a computer as a human would. It’s just one of a wide range of new and advanced capabilities, OpenAI says, including mathematical proficiency, software engineering, and defensive cybersecurity. But “computer use is a particularly important part of what’s new,” OpenAI cofounder and president Greg Brockman told reporters today. The model “can zip through spreadsheets, fill out forms, and navigate across web pages often at superhuman speed,” he said. The company shared a video with reporters of someone sitting on a chair, instructing the computer with their voice in what appeared to be a seamless, albeit staged, interaction. Computer use “shows how far we’ve come from sort of aspirationally training for computer use to bringing real value to people every day,” Mia Glaese, vice president of research at OpenAI, said. OpenAI also released benchmark assessments that showed Astra beats its previous best model, GPT-5.6 Sol, as well as the best current models from its rival Anthropic, Claude Fable 5.1, on a wide range of tasks. On ARC-AGI-3, a difficult benchmark that is meant to test a model’s ability to apply reasoning to situations it has not encountered before, Astra scored 99.9% when using a souped-up harness (basically a set of tools the model can use to help it complete the task) and 66% using ARC-AGI-3’s standard harness, whereas GPT-5.6 Sol had scored only 7.8%, and Anthropic’s Claude Opus 5 only 30%. Astra also scored 100% on ExploitBench, a tough cybersecurity challenge, beating GPT-5.6 Sol’s 78.5% result. OpenAI is not first to market with an AI agent that can use a computer—Anthropic pioneered the space with a beta program in 2024, and Perplexity built
