AI API Tool
PRODUCT OVERVIEW
SiliconFlow is a one-stop large-model API platform for developers and enterprises building AI applications. It provides out-of-the-box APIs covering language, speech, image and video models, billed by usage, so applications can go live quickly. Beyond APIs, it offers reserved instances for core inference workloads with dedicated compute, precision guarantees and cost optimization, inference acceleration based on a self-developed engine, and private deployment for enterprise scenarios. The platform emphasizes high-speed inference, cost efficiency, stability, security and scalability, with support for BYOC deployment and domestic heterogeneous GPUs. It serves industries such as internet, education, government, intelligent computing centers and AI hardware. Access options include pay-as-you-go API usage, reserved instances, and enterprise private deployment.
Log in to the SiliconFlow cloud console and create an API key from the account page to authenticate model calls.
Browse the model list and pricing page to compare input, output and cache costs across providers before selecting a model.
Integrate the model API into your application; usage is billed by volume according to the published model prices.
For enterprise core inference scenarios, review reserved instances for dedicated compute, precision guarantees and cost optimization.
Integrating language, speech, image or video model APIs into applications
Comparing input, output and cache costs across models before production selection
Running core inference workloads on reserved instances
Deploying models privately for enterprise scenarios
The platform provides APIs covering language, speech, image and video models, with a model catalog and pricing page for comparison.
API usage is billed by volume according to the published model prices; chat model prices are shown per million tokens, while image, speech and video models have their own billing units.
The pricing page lists some models as free, such as certain embedding, speech and translation models. Availability and pricing are shown on the pricing page.
Reserved instances target enterprise core inference scenarios, providing dedicated compute, precision guarantees and cost optimization.
Yes, the platform offers enterprise private deployment addressing model performance optimization, deployment and operations, and supports BYOC deployment.
API documentation is available at api-docs.siliconflow.cn, including a user guide introduction.
After logging in to the cloud console, you can create an API key from the account page to authenticate model calls.
The platform lists solutions for internet, education, government, intelligent computing centers and AI hardware scenarios.
Prices are per million tokens for chat models unless otherwise stated; some models are listed as free. Image, speech and video models are billed per image, per second or per video as shown on the pricing page. Reserved instances and private deployment are quoted separately.
