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".
