An AI and LLM enthusiast has conducted an experiment where OpenAI’s new GPT-6 Astra played through the entirety of Valve’s Portal 3D puzzler game on its own. This seems like a remarkably progressive step forward for LLMs and a convincing demonstration of multimodal ‘AI intelligence.’ It wasn’t that long ago AIs were losing at Atari 2600 chess. However, this puzzle gaming task resulted in 3,336 tool calls and a headline API cost of $571.18. CozyBlaze, the enthusiast, has since clarified that the costs were covered by their $200 Codex Pro subscription.

Full report : Astra had to map 3D game spaces and understand the puzzles before it could plan solutions and succeed.
