Model Card
GLM-4.5-AirX is the ultra-fast inference variant of Z.ai's GLM-4.5-Air, a 106B-parameter Mixture-of-Experts model with 12B active parameters per forward pass. It shares the same architecture and 128K-token context window as GLM-4.5-Air but is optimized for maximum throughput and minimal latency.
GLM-4.5-Air itself delivers strong results — scoring 59.8 across 12 industry benchmarks and outperforming models like Gemini 2.5 Flash and Qwen3-235B on reasoning evaluations. AirX preserves that capability while targeting low-latency, high-concurrency production scenarios.
Best suited for real-time agent pipelines, high-volume chat, and latency-sensitive coding assistance where the full GLM-4.5's throughput is insufficient but you still need competitive reasoning and tool-use performance.

More AI Models From Z.AI
GLM 5.1
GLM-5.1 is a frontier-class reasoning model from Z.ai (formerly Zhipu AI), built as a post-training refinement of GLM-5 with a focus on coding and agentic tasks. It uses a 744B-parameter Mixture-of-Experts architecture with 40B active parameters per token and supports a 200K context window. GLM-5.1 scored 58.4 on SWE-Bench Pro, surpassing GPT-5.4 (57.7) and Claude Opus 4.6 (57.3), and reached 95.3 on AIME 2026. It excels at long-horizon agentic workflows, multi-step tool use, and complex software engineering tasks. The model is text-only — no image or audio input.
ChatGLM 5 Turbo
GLM-5 Turbo is a foundation model by Z.ai optimized for fast inference and agent-driven workflows, excelling at tool invocation, complex instruction decomposition, and long-chain task execution in OpenClaw scenarios. It is built on top of the GLM-5 architecture (744B parameters, 40B active) with DeepSeek Sparse Attention for reduced deployment cost and up to 205K token context. GLM-5 Turbo supports reasoning/thinking mode and is designed for real-world multi-step agentic tasks including scheduled, persistent, and high-throughput operations.
ChatGLM 5
GLM-5 is Zhipu AI's (Z.ai) fifth-generation flagship open-weight foundation model with 744B total parameters (40B active) in a Mixture of Experts architecture, designed for agentic engineering, complex systems coding, and long-horizon agent tasks. It achieves state-of-the-art performance among open-weight models on coding and agentic benchmarks like SWE-bench Verified and Terminal Bench 2.0, approaching Claude Opus 4.5-level capability.
