Can I use DeepSeek for code and automation?
Yes. Use the OpenAI-compatible API for coding and automation workflows, then check live pricing for the current DeepSeek model list and access status.
Can I use my existing OpenAI SDK?
Yes. Point the SDK at the flatkey /v1 base URL, use a flatkey API key, and choose the DeepSeek model id you need.
Do I have to change my code?
No. flatkey.ai is OpenAI-compatible: keep your existing OpenAI SDK and switch base_url plus api_key. Model ids stay the same.
How is billing handled across models?
One plan covers every model. Usage analytics and a single invoice keep spend bounded before you scale.
