GLM 4.5

GLM 4.5 is Z.ai's foundation model with a 131K-token context window for processing documents and conversations.

Strengths

Provides broad capability across text understanding, generation, and reasoning tasks with a moderately sized context window for handling substantial documents.

Best for

General-purpose tasks requiring solid reasoning and language understanding without the overhead of larger or more specialized models.

Limitations

Superseded by GLM 4.6 and later releases in Z.ai's lineup, with a smaller context window than GLM 4.7 and subsequent models; not suited for multimodal inputs or tasks requiring very long document processing.
