## Our verdict

K3 is a generational leap: 2.8T parameters vs 1T, roughly 2.5x scaling efficiency, always-on reasoning and frontier-class coding (SWE-Bench Pro 70.0 vs 56.0). K2 keeps two advantages. A 2M context window (vs 1M) and much cheaper tokens ($0.5/$2 vs $3/$15). For agents, coding and hard reasoning, K3. For bulk long-document pipelines on a budget, K2 still earns its keep.
