GLM 5 Turbo

GLM 5 Turbo is Z.ai's optimized inference variant released in February 2026, designed for faster execution with a 202K-token context window.

Strengths

It balances inference speed and capability, enabling efficient processing of multi-turn conversations and extended documents at lower latency than the full GLM 5 model.

Best for

Applications requiring responsive real-time interactions with moderate context lengths, or deployments where inference speed is prioritized over maximum reasoning capacity.

Limitations

It trades some reasoning capability for speed compared to GLM 5 and later foundation models, and its context window is smaller than the 1M-token variants released in subsequent versions.
