)

response = client.chat.completions.create(
    model="deepseek/deepseek-r1",
    messages=[{"role": "user", "content": "Explain quantum entanglement"}],
    max_tokens=512,
)
print(response.choices[0].message.content)

Frequently Asked Questions

Why use TheRouter for SiliconFlow instead of calling SiliconFlow directly?

TheRouter adds automatic failover (SiliconFlow fails → Bedrock takes over), a single API key for all providers, usage analytics, spend controls, and team governance — all without changing your code.

Which SiliconFlow models are free on TheRouter?

Three models are completely free: Qwen3-8B (general chat), DeepSeek-R1-Distill-Qwen-7B (reasoning), and DeepSeek-OCR (document extraction). No credit card required, no usage limits.

Does SiliconFlow support streaming and function calling?

Yes. SiliconFlow's API is OpenAI-compatible and supports streaming, function calling (tools), and reasoning content passthrough. The reasoning_content field from DeepSeek R1 is preserved end-to-end.

What is SiliconFlow?

SiliconFlow is a high-performance AI inference platform with 200+ optimized models, OpenAI-compatible APIs, and a privacy-first approach — no data stored, ever. TheRouter integrates with their international platform at siliconflow.com.
