  "account": "OpenAI's latest GPT-6 Astra model demonstrated its prowess by autonomously completing Valve's Portal puzzle game in just 24 hours. This groundbreaking achievement marks a significant leap forward in AI intelligence and showcases the model's multimodal capabilities. During the process, GPT-6 Astra made a total of 3,336 tool calls, resulting in an API cost of $571.18. However, the enthusiast behind the experiment, CozyBlaze, clarified that these costs were covered by their $200 Codex Pro subscription. The model relied on the Model Context Protocol and a modified SourcePauseTool to navigate the game, with Astra executing its moves and inputs when given the green light. Although the full 24-hour VOD showcases the AI's thought process, the edited highlights reel is just over 2 hours long. This remarkable feat brings us one step closer to OpenAI's original goal of creating a single agent capable of solving a wide variety of games, a vision first set in 2016.",
