GLM 5.2

GLM 5.3 Flash

ox-alpha out of stealth! GLM-5.3 Flash is Z.ai's first natively multimodal GLM-5 model, with 320B total parameters and just 18B active parameters for efficient coding, agentic work, and precise 1M-token context. Its hybrid sparse-and-linear attention architecture helps it outperform GLM-5.2 at one-tenth the price while approaching Claude Opus 4.8 on coding and agentic benchmarks.

GLM 5.3

GLM-5.3 for long-horizon autonomous coding and engineering workflows. This variant defaults to the model's low reasoning tier for faster responses.

GLM 5.3 Thinking

GLM-5.3 with higher reasoning enabled for harder long-horizon coding, autonomous agent workflows, and complex engineering tasks.

GLM 5.3 Flash Uncensored

GLM 5.3 Flash Uncensored is an FP8 uncensored fine-tune of the efficient 320B mixture-of-experts reasoning model with restored vision support, built for unrestricted chat, creative writing, coding, agentic work, tool use, and long-context tasks.

GLM 5.2 Thinking

GLM-5.2 with thinking enabled for harder long-horizon coding, autonomous agent workflows, complex engineering optimization, and real-world development tasks.
