The ARC-AGI-3 scorecard is extremely misleading given that it clearly states itself that "with [the responses API] harness, we estimate Sol would score in the ballpark of ~30%." but it shows a score of 7.8% for GPT-5.6 Sol presumably since if they updated the percentage for GPT-5.6 Sol to the score it would receive with the responses API harness they used for GPT-6 Astra they'd have to do the same for the percentage…
What a sad thing to say. These models are not even better than me at _writing code_, which is as well-suited a task for LLM agents as can possibly be, what with the structured environment and the exabytes of free annotated training data.
Of course, they are also not better than humans at writing, let alone at talking to my daughter, running a pathfinder campaign, decorating a room, being a therapist, etc.
