GLM 5.2 is Z.ai's large reasoning model for long agent runs and project-level coding, and it suits teams that want open weights with a very long context. The Hugging Face card lists 753B parameters under an MIT licence and describes a 1M-token context. OpenRouter gives a 1,048,576-token window, text only, and a listing date of 16 June 2026. OpenRouter's headline price is $0.006 per million input tokens and $6.80 per million output tokens, but that comes from a single route, and the input figure is an outlier. Other routes on the same list charge about $0.19 to $0.65 for input and $1.44 to $8 for output, so price the route you will actually use, not the headline. The card does not publish rate limits or hardware needs, and the weights are far too large for a single workstation. It also points to a newer GLM 5.3 release, so this is no longer the maker's latest. Figures come from the Hugging Face card and the OpenRouter model list. We have not run it ourselves. We would use it where a million tokens of context matters, and test it against the newer GLM models first.
