The capabilities, trade-offs and people behind China’s AI models.
Zhipu AI has begun limited grayscale testing of GLM-5.3-Highspeed on its Zcode platform, with a user reporting output speeds up to 490 tokens per second — more than double the previous GLM-5.3-FlashX variant. The model remains in random subscriber rollout and is not yet generally available.
Chinese AI startup Shengshu Technology has released a preview of Vidu Q4, its next-generation video generation model supporting 4K/10-bit output, 16-second generation, and expanded multimodal reference inputs of up to 15 images and 3 audio tracks, positioning China's domestic video models closer to film-grade production quality.
Lenovo TianxiAI's self-developed code agent framework TianxiCode achieved a 71% problem-solving rate on the SWE-bench-Live Lite benchmark, ranking first globally with Verified certification. Running on DeepSeek-v4.1-Flash as its foundation model, the result highlights the growing competitiveness of Chinese-developed AI coding agents on international engineering benchmarks.
ByteDance updated its Doubao Work productivity platform on October 9 with an infinite canvas feature for multimodal creation, integration of the Seedream 5.0 Flash image generation model, and launch of Doubao 2.1 Lite optimized for office tasks. The update deepens multimodal AI integration in Chinese enterprise productivity tools.
ComfyUI has demonstrated that MiniMax H3, a video generation model from Shanghai-based Chinese AI lab MiniMax, can produce live video at real-time speed on a single RTX 5090 consumer GPU through engineering optimizations including sparse attention, INT8 quantization and a fused FP4 MLP, reducing VRAM requirements from 80GB to under 30GB and making Chinese AI video generation accessible beyond expensive cloud infrastructure.
Amazon Web Services has integrated Zhipu AI's GLM-5.3 open-weight model into its Bedrock platform under a usage-based revenue-sharing agreement, marking a major commercial milestone for a Chinese large language model company seeking global enterprise distribution through Western cloud infrastructure. Zhipu's Hong Kong-listed shares rose more than 7% on the news as investors recognized the deal as validation of the company's multi-cloud internationalization strategy.
