GLM-5.2 vs Kimi K3

Side-by-side comparison of GLM-5.2, Kimi K3: pricing, capabilities, integrations and compliance — from verified HokAI records.

GLM-5.2

Z.ai

Pick it if: GLM-5.2 is Z.ai's flagship released June 13, 2026 on a 744B MoE architecture with 40B active parameters and a 1,000,000-token context window. Priced at $1.40/$4.40 per 1M tokens under an MIT license, it scores 80.3% GPQA Diamond and 62.1% SWE-bench Pro.

Its edge: Tops open-source SWE-bench Pro at 62.1% as of June 2026, 3.7 points ahead of predecessor GLM-5.1.

The catch: No native image, audio, or video input — vision tasks require the separate GLM-5V-Turbo model.

Kimi K3

Moonshot AI

Pick it if: Kimi K3 launched July 16, 2026 with 2.8 trillion total parameters (280B active) and a 1,048,576-token context window, the largest announced open-weight-class model to date. It targets teams doing agentic coding and long-document analysis who want an open alternative to GPT-5.6 Sol and Claude Opus 4.8.

Its edge: Highest published open-weight GPQA Diamond score at 93.5%, ahead of Opus 4.8's 91.0%.

The catch: Hallucination rate rose to 51% on AA-Omniscience versus 39% for predecessor K2.6, more confident fabrication despite higher accuracy.
