The National Supercomputing Internet Platform has launched the official API service for the DeepSeek-V4-Flash-0731 model and simultaneously opened access to model file downloads. This version, after extensive post-training, achieves significant improvements in agent capabilities and instruction following, with performance on multiple benchmark tests now comparable to the strongest proprietary models. The platform has now aggregated over 1,700 popular open-source large models from both domestic and international sources, covering mainstream series such as DeepSeek, GLM, and Qwen, and has become the nation’s first ultra-scale AI computing resource pool with over 100,000 accelerators, providing developers with an all-in-one infrastructure spanning from computing power supply to model services.Article author and source: National Supercomputing Internet
DeepSeek has officially released the stable version of the V4-Flash model and simultaneously launched its API public beta. The National Supercomputing Internet Platform has immediately enabled API access and model file downloads for this model. The official release, named DeepSeek-V4-Flash-0731, has undergone extensive post-training, significantly enhancing its agent capabilities and instruction following. Its performance on multiple benchmark tests now rivals that of the strongest proprietary models available today.
For developers and enterprise users, the integration barrier has been minimized to the utmost. Users need not perform complex environment setup; simply log in to the National Supercomputing Internet website via PC, navigate to the “Services” menu on the homepage, and enter the “Model Services” section to instantly access the API invocation page. In addition to online invocation, users can download model files and leverage the platform’s secure and trusted Notebook development environment to complete the entire development workflow—including fine-tuning, deployment, and adaptation optimization—in one seamless step.
Over 1,700 models come together as China's open-source ecosystem accelerates its formation
The significance of this launch extends beyond the opening of a single model. The National Supercomputing Internet AI Community has now accumulated over 1,700 popular open-source large models from both domestic and international sources, covering mainstream series such as DeepSeek, GLM, Qwen, and Kimi. It has also fully launched API interfaces for multiple domestic open-source large models, including DeepSeek-V4, MiniMax-M3, and Kimi-K3. This enables developers to compare, invoke, and switch between multiple models on a single platform, significantly reducing the cost of experimentation in AI application development.
More importantly, with the official launch of its core nodes, the National Supercomputing Internet has become the country’s first ultra-large-scale AI-integrated computing resource pool exceeding 100,000 accelerators. From underlying computing power supply to upper-layer model services, this national platform is building a complete AI infrastructure chain—when DeepSeek’s latest models can be accessed by developers nationwide with a single click, the deployment speed and reach of domestic large models may be entering a new turning point.
