Gameplay trajectories from the harness×model pair codex-gpt5.5 playing the
ARC-AGI-3 game g50t, part of the
ARA-as-world-model generalization experiment. The agent builds a structured world model
(an Agent-Native Research Artifact) live during play and consults it to crack levels it
cannot solve from cold exploration.
One dataset repo per harness×model×game: sibling repos
arc-agi3-
-- hold the same game… See the full description on the dataset page: https://huggingface.co/datasets/AgentNativeResearchLab/arc-agi3-codex-gpt5.5-g50t.
