Zhipu AI

GLM-5.3 is Zhipu AIs open-weights model from August 2026 — a MoE model focused on coding and cybersecurity that tops the open-model field on agentic benchmarks.

Open model from Zhipu AI (Z.AI), released in February 2026 under the MIT license. A mixture-of-experts with around 744B parameters (about 40B active per token), 200K context, focused on coding and agents. Freely downloadable via Hugging Face.

GLM-5.2 (June 2026) is Zhipu AIs (Z.ai) open-weight model — an MoE with around 744B parameters (~40B active), a 1M-token context and MIT license, strong at agentic coding.

GLM-4.5 is an open model from Zhipu AI (Z.ai) released in July 2025. It is an agent-native Mixture-of-Experts model with 355 billion parameters (32 billion active), a 128,000-token context and an MIT licence.

GLM-4.6 is Zhipu AI's open-weight MoE model from September 2025 — 355B parameters (32B active), 200k context, MIT-licensed, with a focus on coding performance.

GLM-4.7 (December 2025) is Zhipu AIs open-weight coding flagship — an MoE model with roughly 400B parameters, a 200K input context and the "Preserved Thinking" feature.

GLM-5.1 is Z.ai's open-source flagship from April 2026 — 744B parameters (40B active), 200k context, designed for agentic coding with up to 8 hours of autonomous runtime.
