Z.ai

Z.ai, formally Knowledge Atlas Technology Joint Stock Co., Ltd., is a Chinese technology company specializing in artificial intelligence. Previously known internationally as Zhipu AI, the company rebranded to Z.ai in 2025. Its core focus is the GLM family of…

GLM 5 is Z.ai's current-generation large language model, offered here in an end-to-end encrypted configuration running inside a Trusted Execution Environment (TEE). Hardware attestation evidence allows independent verification of enclave identity and configuration, making this variant especially suited for privacy-sensitive workloads. The underlying GLM 5 was first released in February 2026, with this TEE-secured variant following in March 2026.

Within Z.ai's lineup, GLM 5 sits above the older GLM 4.7 and GLM 4.6 generations and below the newer GLM 5.1. Siblings include GLM 5 Turbo, optimized for speed, and GLM 5V Turbo, which adds vision capabilities. The model is released under the MIT license, continuing Z.ai's commitment to open-source AI since mid-2025. It supports a generous 198k-token context window and is served in FP8 quantization.

With built-in reasoning and web-search capabilities paired with TEE-backed encryption, this variant is best suited for users who need strong general-purpose text generation while maintaining verifiable privacy guarantees over their prompts and outputs.
