GLM 5

by Z.ai

Released 23 days after GLM 4.7 Flash · All Z.ai releases

GLM-5 is Zhipu's fifth-generation frontier foundation model released February 2026, with 744 billion total parameters and 40 billion active in a Mixture-of-Experts configuration. Zhipu reports it was trained entirely on Huawei Ascend chips using the MindSpore framework, without NVIDIA hardware, a notable step toward large-model training independent of US semiconductor supply chains. The model reports open-source state-of-the-art results in coding and agentic tasks, with real-world programming capability that Zhipu benchmarks directly against Claude Opus 4.5. Trained on 28.5 trillion tokens, it integrates DeepSeek Sparse Attention to reduce deployment cost while preserving long-context capacity, with a 200K context window. Its reasoning-first design emphasizes thought quality and multi-step problem decomposition, making it strong for software engineering, mathematics, and frontier reasoning. Released under an MIT license, GLM-5 targets developers building state-of-the-art coding agents, research systems, and reasoning-intensive applications. Its roughly two-fold scale increase over GLM-4.5 combined with sparse activation aims to deliver capability gains while keeping inference practical.

Uptime and availability

One of GLM 5's 2 routes is on the monitoring board, so the figure below is that provider's availability rather than the model's.

100%route uptime, last 30 days

Its other routes aren't measured here yet.

Name a second model in the same request and the gateway tries it on retriable errors, so a busy hour never has to reach your users. Set up a fallback chain.

Measured over the last 30 days from each provider's official status feed via StatusGator. Refreshed hourly. 1 further route is not on the board yet. See uptime for every provider Opper monitors.

Data handling per route

Each route hosting GLM 5 has its own privacy posture, residency, and GDPR terms. Postures are maintained by Opper with a last-verification timestamp.
