K3 is a separate model from the K2.6 historical evaluation.

Suggested starting role: complex planning. The documented focus on long-horizon software engineering and reasoning makes K3 a planning and extended-agent candidate. Its large context is not itself evidence of higher accuracy. This is editorial guidance, not a benchmark score.

Prices are USD per million native tokens, with input and output billed separately. Extra reasoning tokens, retries, tool calls, cache writes, storage, and taxes can change the bill. Use-case tags reflect our reading of official capabilities, not measured rankings.
