Scores are percentages reported by model creators or benchmark maintainers under varying settings. A blank is preferable to an inferred result. See our methodology.
GLM-5.2 strengths
- One-million-token context
- Coding and agent focus
GLM-5.2 limitations
- Downloadable-weight status and license unavailable
