Overview
SiliconFlow is a domestic AI inference platform known as 'the lowest price on the internet', offering API services for mainstream models such as DeepSeek, Qwen, and Llama. With domestic computing power and an optimized inference engine, it significantly reduces call costs while maintaining performance, making it a popular choice for domestic developers using open-source models.
Key Features
- Lowest Price API on the Internet: API prices for mainstream models are lower than official and other platforms.
- Multi-Model Aggregation: One-stop access to mainstream models such as DeepSeek/Qwen/Llama/Mistral, with newly added high-speed versions like GLM-5.2, Kimi K2.7, and DeepSeek-V4-Pro Flash.
- Domestic Computing Power: Deployed in domestic data centers, offering low latency and compliance without worries.
- OpenAI Format Compatibility: API interface is compatible with OpenAI SDK, with zero migration cost.
- Free Credits: New users receive free Token credits upon registration.
- High-Speed Inference: Language model speed increased by more than 10 times, image generation in 1 second, and voice generation in 100 milliseconds.
- High Stability: Provides comprehensive monitoring and fault tolerance mechanisms, with professional technical support to ensure high availability.
- High Security: Supports BYOC deployment with isolated computing, networking, and storage, meeting industry standards and compliance requirements.
- Reserved Instances: A one-stop solution for enterprise core inference scenarios, providing exclusive computing power, precision assurance, and cost optimization.
- Private Deployment: Offers enterprise-level private deployment solutions, addressing pain points such as model performance optimization, deployment, and operation and maintenance in one go.
