What is DeepSeek used for?
DeepSeek offers a web chat for individual prompts and a developer API for applications. Try one question, a writing revision or a programming explanation in the web chat to see whether the response fits your task.
Who should start here?
Use the web chat if you want to try one explanation or draft. Use the API docs if you need to put a model behind your own interface. For the chat route, try the same prompt in ChatGPT and compare the answers against a source you trust.
Try one answer you can verify
- Ask one question and state what a useful answer should contain.
- Check factual claims against an original source and run any generated code in a safe test project.
API access and pricing
Use the API documentation for authentication, supported interfaces and current token charges. Check the model and any additional tools your request will use before estimating costs.
A few more details
Where do I find API pricing?
