  • Tech outlet Wccftech reports that Moonshot AI is preparing to release the Kimi K3.1 model.
  • The leak claims K3.1 is expected to arrive in October 2026 and will offer three reasoning intensity tiers: Low, High, and Max.
  • Model identifiers tied to K3.1, such as k3d1-agent, have appeared in internal API responses.
  • Configuration files indicate K3.1 may support Agent mode, Swarm multi-agent collaboration, and search batching.
  • K3.1 may offer an Extra Long context option supporting up to 1 million tokens.

PHYSIX OBSERVATION

By turning reasoning intensity into a three-tier switch, K3.1 hands the choice over compute cost to users, which is more pragmatic than simply piling on parameters. If Swarm and Agent mode ship, Moonshot will shift from a model vendor to an agent platform, but the leak comes from API fields, and the real capabilities still await official verification.
