GLM 5 is Z.ai's foundation model with a 198K-token context window, released in early 2026 as an intermediate step before the expanded-context GLM 5.1 and subsequent releases.
- Strengths
- Handles extended documents and multi-turn conversations within its context window, with the reasoning capabilities of Z.ai's generation 5 models.
- Best for
- General-purpose text generation, reasoning, and document understanding tasks that fit within a 198K-token budget.
- Limitations
- Smaller context window than GLM 5.1 and later models; superseded by GLM 5 Turbo for faster inference and by GLM 5.1 and above for larger context requirements.
