Description

About Z.ai: GLM 5.2.

A Z.ai model for long-horizon tasks, released with open weights under the MIT licence for English and Chinese text generation. It steps up from GLM-5.1 by sustaining work over a one million token context. It offers several thinking effort levels to trade quality against latency, and an indexer-sharing design that cuts per-token compute at that context length. Its multi-token prediction layer also helps speculative decoding.
