GPT-6 Astra clears Portal autonomously for $571 in API costs
TL;DR
- OpenAI's GPT-6 Astra completed the original Portal on its own, using 3,336 tool calls across almost 24 hours and $571.18 in API charges.
- A hobbyist posting as cozyblaze wired the model to screenshots and player coordinates, pausing the game each time Astra decided its next move.
- Portal has been documented extensively online, so the run does not show Astra can beat an unfamiliar game from scratch.
OpenAI's newest model, GPT-6 Astra, played through the original Portal on its own. The run took 3,336 tool calls, ran for close to 24 hours, and cost $571.18 in API usage, according to The Verge.
The setup was hobbyist. A researcher who posts as cozyblaze on X connected the model to the game, fed it screenshots and player coordinates, and let it choose the next action. The game paused each time the model thought, so active play added up to roughly two hours out of the 24. The rig leaned on 'GPT-6 Astra's updated context-management system, allowing the agent to retain information across the long sequence of decisions.'
'I didn't expect this to happen so soon,' cozyblaze wrote on X, adding that 'back in 2016, one of OpenAI's technical goals was to solve a wide variety of games using a single agent.'
There is a large asterisk. Portal 'has been documented extensively, so the run does not show that GPT-6 Astra can solve any unfamiliar game from scratch.'
It is not a benchmark.
