Moonshot AI has begun a full rollout of Kimi K2.8 Preview to Kimi Code CLI, according to BlockBeats. Users do not need to switch model IDs, as the existing kimi-for-coding endpoint will now point directly to the new model. Kimi said K2.8 Preview delivers overall performance close to K3 while running thinking tasks more efficiently. The model also adds the same thinking-intensity controls available on K3 and expands context length to 1 million tokens. By comparison, the previous K2.7 Code version supported a 256K context window and only allowed thinking to be turned on. The update effectively brings two core capabilities from K3 into Kimi’s default coding model.
