Do AI solvers already do Peircian abduction? Researchers debate the induction boundary on ARC-AGI

Balázs Kégl asks @IntuitMachine and @LucaAmb whether current reasoning solvers already perform Peircian abduction — the inference to the best explanation. He argues medical-advice applications will require it, and he is unsure whether we're already there.
His follow-up sharpens the question: is induction alone enough to solve ARC-AGI, or is the line between induction and abduction inherently blurry?
- Abduction, alongside deduction and induction, means inferring the best explanation from observations.
- The debate: do LLM-based solvers' success on benchmarks like ARC-AGI reflect mere pattern induction, or genuine abductive reasoning?
- The answer bears directly on whether models can handle high-stakes explanation-finding tasks like medical advice.
