GLM 4.5

GLM 4.5 is Z.ai's foundation model released in mid-2025 with a 131K-token context window for processing documents and multi-turn conversations.

Strengths

Handles extended context and complex reasoning tasks across text-based workloads.

Best for

General-purpose tasks that require moderate context length and broad capability without multimodal input requirements.

Limitations

Superseded by later foundation models (GLM 4.6 and newer) that offer larger context windows and improved performance; for multimodal inputs use GLM 4.5V instead.
