Compares input/output pricing per 1M tokens, 1M context coverage, coding benchmarks (SWE-bench/Terminal-Bench), multimodal support, and best-fit scenarios. Cheapest is GLM-5.3-Flash (5折 ends 9/9, $0.075/$0.25); most expensive is Qwen3.8-Max ($1.20/$3.60). All 8 are open-weight capable or have public APIs.
Frequently Asked Questions
Which Chinese LLM is the cheapest in September 2026?
GLM-5.3-Flash from Zhipu AI at promotional $0.075 input / $0.25 output per 1M tokens (50% off, ends 9/9). After Sep 9 it reverts to $0.15/$0.50. For permanent low price, DeepSeek V4 Flash at $0.14/$0.28 per 1M (cached input $0.0028/M). Qwen-Flash (0-256K) is also $0.05 input but only 256K context.
Which Chinese LLM has the longest context window?
As of September 2026, multiple Chinese LLMs support 1M tokens: DeepSeek V4-Pro, Qwen3.8-Max, GLM-5.3, Kimi K3, mimo-v2-pro, MiniMax-m3. ByteDance doubao-2.0-pro is 256K. Tencent Hy3 is 256K. For pure length leaders, Kimi K3 (originally pioneered 2M context but standard tier is 1M) and Qwen3.8-Max (2.4T params, 1M) are the most flexible.
Is DeepSeek V4-Pro better than GLM-5.3 for coding?
Both score around 80% on SWE-bench Verified. DeepSeek V4-Pro is $0.435/$0.87 per 1M (75% permanent discount). GLM-5.3 is $1.40/$4.40 list (currently 10% off, $1.26/$3.96). DeepSeek is ~3x cheaper. For coding agents with heavy cache use, DeepSeek V4-Pro's cache hit at $0.003625/M (90% off) makes it dramatically cheaper on long-context workloads. For visual coding (frontend/screenshots), GLM-5.3-Flash has native multimodal vision input.
Which Chinese LLM is best for agent workflows in 2026?
For pure agent quality, DeepSeek V4-Pro leads on SWE-bench Verified (80.6%) and CyberGym. For agent cost optimization, GLM-5.3-Flash has the lowest API bill (5折 $0.075/$0.25 through 9/9). For multimodal agent work, mimo-v2-pro and GLM-5.3-Flash both support vision input. For long-context agents (RAG over large docs), Qwen3.8-Max and Kimi K3 at 1M context are the safe picks.
Are Chinese LLMs open weight? Can I self-host?
Most have some open weights: DeepSeek V4 (V4-Flash 284B/13B active), Qwen3.8 (multiple sizes), GLM-5.2 (MIT license), Kimi K2 (1.1T but commercial-only). GLM-5.3 weights promised ~2 weeks after Aug 14 launch (late August target) but with safety review delay. Tencent Hy3 weights exist for some sizes. For self-hosting today, DeepSeek V4-Flash is the most accessible; for commercial use, all 8 have public APIs with China-hosted endpoints.
