China Model Watch — July 2026: Kimi K3, GLM-5.2, DeepSeek-V4, Qwen3.8
A developer-facing snapshot of the Chinese model stack as of late July 2026 — focused on API access, context, open weights, and how to route traffic vs GPT-5.6 Sol / Claude Opus 5.
In July 2026 the Chinese open/API stack re-based around four names: Kimi K3, GLM-5.2, DeepSeek-V4-Pro, and Qwen3.8-Max-Preview. Western comparison baselines are GPT-5.6 Sol and Claude Opus 5 — not GPT-5.5 / Opus 4.8.
What changed this month
- Moonshot Kimi K3 — ~2.8T-class frontier, 1M context, native vision; open weights rolling out late July.
- Zhipu GLM-5.2 — long-horizon coding/agents, 1M context, MIT-class open weights; widely used as a cost-efficient SWE model.
- DeepSeek-V4-Pro / V4-Flash — 1.6T MoE / Flash family with 1M context; agentic coding value leaders.
- Alibaba Qwen3.8-Max-Preview — ~2.4T multimodal preview (WAIC window); treat as preview, confirm IDs before production lock-in.
- Video — Seedance 2.0 still the common API target; 2.5 discussed as rolling on Dreamina.
How builders should route traffic
| Workload | Prefer first |
|---|---|
| Long multi-file coding agents | glm-5.2 · deepseek-v4-pro · kimi-k3 |
| Cheap high-volume chat / classify | deepseek-v4-flash · qwen-plus tier |
| Huge docs + vision | kimi-k3 · qwen3.8-max-preview |
| Western closed baseline | gpt-5.6-sol · claude opus 5 |
Always confirm live model IDs in your ChinaModelAPI dashboard — aliases move faster than marketing names.
