GLM 5.2 (batch)

GLM 5.2 is Z.ai's reasoning model with a 512K-token context window for processing extended documents and complex multi-step tasks.

Strengths

Handles long-horizon reasoning workflows and extended contexts, enabling processing of substantial document sets and complex project-level tasks.

Best for

Long-document analysis, multi-step reasoning, and agent workflows requiring sustained context over extended interactions.

Limitations

Reasoning-focused positioning makes it less suitable for tasks where speed or cost efficiency is the primary concern; a later foundation model may be preferable for simpler requests.
