OpenAI's GPT-6 Astra AI model has autonomously completed the Portal puzzle game, demonstrating advanced reasoning and problem-solving capabilities. A user (cozyblazex) documented the feat, showing Astra using SourcePauseTool to pause gameplay during computation cycles. The achievement consumed ~571 USD (~19,000 THB) in API token costs, highlighting both the model's capability gains and the economic implications of running sophisticated AI agents—relevant for Thai SMEs evaluating generative AI ROI and operational costs.
