Demonstrates the practical capability of advanced, fine-tuned models to autonomously perform complex tasks that require planning, decision-making, and interfacing directly with a real system over a long duration.
AI Summary
In an experiment testing autonomous AI capabilities, the user gave a custom-tuned GPT model (GPT-5.6 Sol in Codex) direct control over their computer with the goal of winning the daily challenge in the complex roguelike game Slay the Spire 2. The AI successfully played the game autonomously for 5 hours, making complex strategic decisions to beat the randomized challenge. The result exemplifies a significant threshold in AI's ability to understand and execute multi-step objectives in a dynamic, unpredictable environment.

This was one of those impressive AI thresholds for me. I gave GPT-5.6 Sol in Codex control over my computer, and asked it to win the daily challenge for the game Slay the Spire 2 (randomized factors, so can't cheat). Its a complex game. It worked for 5 hours, making complex game choices... and won.
