SiliconFlow
One OpenAI-compatible API for 200+ open-weight models across text, image, video, and audio.
About
SiliconFlow (Beijing-founded 2023) is an AI inference cloud that hosts a fast-moving catalog of open-weight models, including DeepSeek, Qwen, GLM, Kimi, and Tencent releases, behind a single OpenAI- and Anthropic-compatible API. It covers chat, embeddings, reranking, image generation, video generation, speech, transcription, and voice cloning in one pay-as-you-go interface.
The platform offers serverless inference, dedicated GPU endpoints, and one-click fine-tuning, running on a self-developed inference engine over H100/H200, AMD MI300, and RTX 4090 hardware. It positions itself on speed, predictable cost, and rapid catalog updates, and is widely used by developers who want access to the Chinese open-weight ecosystem without managing GPUs.
