One OpenAI-compatible API for 200+ LLMs and multimodal models
Updated
SiliconFlow is an AI infrastructure platform for deploying, fine-tuning and running 200+ optimized large language and multimodal models through simple APIs.
Developers call a single OpenAI-compatible endpoint and choose a model, and billing is per token. Models can also be fine-tuned or deployed on reserved GPUs. The vendor states that no data is stored and that models stay yours. Recent additions listed include Tencent's Hy4-preview with a 1M token context and DeepSeek-V4.1-Flash.
SiliconFlow is used by developers and companies building AI features who want many open and third-party models behind one API instead of running their own infrastructure.
Pricing is per token and varies by model. DeepSeek-V4.1-Flash is listed at $0.15 per million input tokens and $0.6 per million output tokens, and premium models cost more. Users can get started for free on the cloud platform.
Alternatives include Featherless, which serves open models serverlessly, Lightning AI and Cerebrium, which provide GPU compute and deployment, and NVIDIA NeMo. SiliconFlow stresses a single OpenAI-compatible API over 200+ models.
