GPT-6 Astra: The next generation in intelligence for work

The AI model GPT-6 Astra has autonomously completed the video game Portal in under 24 hours without human intervention. Developer cozyblaze released the project on GitHub, noting the achievement incurred $571 in token costs. This milestone demonstrates significant progress in autonomous agent capabilities, as the model successfully navigated complex game environments and puzzle-solving mechanics independently. The feat serves as a benchmark for how current large language models can handle sustained, multi-step tasks in dynamic, non-textual digital settings.
