GLM-5.3-FlashX-Legal (GLM-Legal) is Z.ai's legal-domain variant of GLM-5.3-FlashX, a native multimodal model that accepts text, image, and video input and produces text. It adds legal-domain mid-training and post-training with reinforcement...

GLM-5.3-Prime is the high-speed variant of Z.ai's GLM-5.3, inheriting its full capabilities while delivering 1.5–2× the output throughput through inference acceleration. It supports text input and output with a 1M-token...

GLM-5.3-FlashX is the high-speed variant of Z.ai's GLM-5.3-Flash, a native multimodal model delivering inference speeds of up to 200 tokens/s. Built on the same hybrid sparse and linear attention architecture...

Natively multimodal model in the GLM-5 series with 320B total and 18B active parameters. The authors say it approaches Claude Opus 4.8 on coding and agentic benchmarks, and it targets efficient long-context serving through a hybrid sparse and linear attention design.

GLM-5.3 is a text model aimed at complex coding and long-horizon agent tasks, built on the same base model as GLM-5.2. The model card reports a 50% gain over GLM-5.2 on the in-house Z.ai Code Bench and 84.5 on CyberGym.

GLM-5.2 is an open-source model from Z.AI for long-horizon tasks, with a stable 1-million-token context and strong agentic coding. It combines code generation with tool use and supports adjustable thinking-effort levels. It scores 62.1% on SWE-bench Pro, sits close to the frontier on AIME and GPQA-Diamond, and improves markedly over GLM-5.1. The MoE architecture with IndexShare cuts compute per token by a factor of 2.9.

SCAIL-2 animates a reference character from a driving video, supports character replacement and multi-character scenes, and works without intermediate pose representations such as skeleton maps.

Direct predecessor of GLM-5.2 (June 20). Still interesting for local deployment. The GLM-5.1 FP8 variant has 1.33M downloads — massive interest from the CN community.

First release of the GLM-5 generation (April 2026). 2.1K likes on HuggingFace. Zhipu's development rhythm is remarkable: one major release per month.
