MIT weights on the current release, data closed, no training pipeline, so 3. Z.ai moved to MIT partway through the family: GLM-4 and GLM-4-9B carried the GLM-4 License, which requires commercial-use registration and a 'Built with GLM' attribution and scored 2, while GLM-4.6, GLM-5.1 and GLM-5.2 are plain MIT. GLM-5.2 governs as the current release. Capability 5 comes from the GLM-5 line; the GLM-4 line scored 2.
