Latest open artifacts (#24): Motif-3, GLM-5.3, Hy4-preview and open model licenses

• The open model ecosystem is rapidly expanding, but increased competition is leading to a divergence in licensing strategies, with Western developers embracing open licenses while some frontier Chinese developers adopt more restrictive custom terms.
• Chinese model makers like Zhipu (GLM-5.3) are implementing custom licenses that include high revenue thresholds (e.g., $10B for GLM-5.3) and undefined terms like “affiliates,” creating significant legal uncertainty and barriers to adoption for Model-as-a-Service providers.
• Notable new “artifacts” include Motif-3 (MIT licensed, strong performance for its size), a preview of Qwen3.8-Flash-Next (featuring n-gram embeddings and new attention mechanisms), and GLM-5.3-Flash (which used a “stealth model” release strategy to generate hype).
