- Issue: Error message stating "Login failed. Your email domain is currently not supported for registration."
- Reason: Your email service provider might not be supported by DeepSeek.
- Solution: Try a different email service provider. If the problem persists, contact [email protected] for assistance.
Billing Inquiries
Is There an Expiration Date for My Balance?
Worried about your balance expiring? The topped-up balance you purchase is designed to last.
- Topped-Up Balance: Your balance will not expire, ensuring long-term usability.
- Granted Balance: Check the expiration date of any granted balance on the billing page for specific details.
API Call Optimization
Understanding API Rate Limits
Managing API rate limits is crucial for smooth operation. Here's what you need to know:
- Dynamic Rate Limits: The rate limit on each account adjusts dynamically, depending on real-time traffic and historical usage.
- No Individual Increase: DeepSeek currently doesn't support manual increases to the dynamic rate limit for individual accounts.
Keep an eye on your usage to avoid hitting these limits and potentially disrupting your application's performance.
API Speed: Web Service vs. API Calls
Noticing a speed difference between the web service and API? There's a reason for that:
- Web Service: Uses streaming output, displaying tokens incrementally as they're generated.
- API (Default): Uses non-streaming output (stream=false), delivering the complete output after generation.
- Solution: Optimize interactivity by using streaming output in your API calls (setting stream=true).
By enabling streaming, you can achieve a more real-time, responsive experience similar to the web service.
Decoding Empty Lines in API Responses
Encountering continuous empty lines when calling the API? It's a keep-alive mechanism. To maintain a stable connection, the API sends empty lines or SSE (Server-Sent Events) keep-alive comments while waiting for the request to be scheduled.
- Non-Streaming Requests: API returns empty lines.
- Streaming Requests: API returns "
: keep-alive" SSE comments.
- Solution: When parsing the HTTP response, handle these empty lines or comments appropriately to avoid errors.
LangChain and DeepSeek API
DeepSeek API is compatible with LangChain, a popular framework for building applications powered by large language models.
- Integration: You can seamlessly integrate DeepSeek's models into your LangChain projects. Also, remember to replace the API key from the code with your actual API key.
- Example: Refer to the demo code provided in deepseek_langchain.py, which shows how to use LangChain with the DeepSeek API.
Calculating Token Usage Offline
