GLM-5 vs Kimi K2 Thinking

GLM-5 vs Kimi K2 Thinking. Z.ai's agentic-engineering flagship against Moonshot's deep-reasoning model. Two top open-weight models compared for 2026.

GLM-5 and Kimi K2 Thinking are two of the strongest open-weight models from China's leading labs, and both top value charts. GLM-5, Z.ai's 744B MoE, is engineered for agentic coding and long-horizon tasks, leading the open-weights intelligence index at launch and excelling in coding harnesses like Claude Code and Cline.

Kimi K2 Thinking, Moonshot's trillion-parameter MoE, is the reasoning specialist — extensive chain-of-thought for hard math, coding and science, with a 256K context. GLM-5 tends to win on agentic engineering and tool-driven coding workflows; Kimi edges the deepest step-by-step reasoning problems. Both are open-weight, cheap and easy to integrate, so the choice hinges on agentic coding versus pure reasoning depth.
