Kimi K1.5

Moonshot AIProprietaryPending Human Review

Kimi K1.5 is Moonshot’s published multimodal reasoning-model research on reinforcement learning with language models. The report emphasizes long chain-of-thought learning, context scaling, and transferring long reasoning into shorter responses. It evaluates mathematical, coding, and visual reasoning tasks and documents the training methodology. This is a historically substantive research release, not a downloadable checkpoint: no public K1.5 weights or training license are established by the report. Parameter count and the complete architecture are not disclosed sufficiently for this catalog.
