Z.ai releases GLM-5.2 open-weights model
Z.ai has launched GLM-5.2, a flagship open-weights model designed with a stable 1-million-token context window for long-horizon software engineering. Released under the MIT license, it features adjustable thinking effort levels and a novel "IndexShare" architecture that reduces per-token compute by 2.9× at maximum context.
GLM-5.2 is a major victory for the open-weights community, proving that open-source alternatives can match or exceed proprietary frontier models in specialized, long-context engineering workflows.
* The IndexShare design demonstrates a highly efficient mechanism to scale context length without the typical linear compute overhead.
* Achieving 81.0 on Terminal-Bench 2.1 makes it the first open-weights model to break the 80% mark, rivaling top closed-source models.
* Releasing under an MIT license provides a vital, border-free resource for global developers restricted by export controls on frontier APIs.
