## Our verdict

Fable 5 keeps the overall capability crown (Artificial Analysis 60 vs 57) and stronger long-horizon agent reliability. K3 counters with a third of the price ($3/$15 vs $10/$50), open weights due July 27 under a modified MIT license, and wins on some published coding benchmarks. For the hardest agentic and research work, Fable 5. For cost-sensitive volume, self-hosting or data-residency requirements, K3 is the strongest open option ever, but verify Moonshot's self-reported numbers on your own workload.
