Notes
- GLM-5.3
- Z.ai's current flagship: same 744B-total / 40B-active base as GLM-5.2, improved only by post-training, with large gains in coding and cyber-security tasks. Weights license is MIT-style and allows commercial use; only a Model-as-a-Service operator with over $10B revenue in 12 months must pass a Z.ai security review first.
- DeepSeek V4 Pro
- DeepSeek's flagship MoE model, 1.6T total and 49B active parameters, open weights under MIT (commercial use allowed, no extra conditions). The API now serves the GA build DeepSeek-V4-Pro-0813 (13 Aug 2026), which DeepSeek says greatly improves agent performance and adds low/high/max reasoning effort.
- Kimi K3
- Moonshot's flagship and the first open 3T-class model: 2.8T total, 104B active parameters, native vision, 1M context. Kimi K3 License allows commercial use, but Model-as-a-Service operators with over $20M revenue in 12 months need a separate agreement, and products over 100M MAU or $20M monthly revenue must display "Kimi K3".
