DeepSeek-V2.5 is a powerful model that combines general dialogue capabilities with advanced code processing. Integrating the functionalities of DeepSeek-Chat and DeepSeek-Coder, it excels in writing, instruction following, and is particularly strong in security and code generation tasks. This model supports various functions, including general dialogue and Fill-In-the-Middle (FIM) completion, and is open-sourced on Hugging Face.
This guide will walk you through obtaining a DeepSeek model API key and performing basic usability tests to ensure efficient integration and reliable operation.
Getting your DeepSeek API key is straightforward. Follow these steps to get started:
Register/Login: Go to the official DeepSeek platform.
Navigate to API Keys: Find the "API Keys" section in the left-hand navigation menu. This page displays all API keys associated with your account.
Create a New API Key: Click on "API Keys" in the left navigation, then select "Create API key."
View and Save Your API Key: After creation, your API Key will be displayed. Important: Copy and save this key securely, as you won't be able to view it again through the API keys management interface due to security reasons.
Once you have your [Deepseek API Key 密钥], testing its availability is vital. Here’s how you can do it using cURL:
Input:
curl -X POST https://api.deepseek.com/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer <DeepSeek API Key>" \
-d '{
"model": "deepseek-chat",
"messages": [
{"role": "user", "content": "你好!"}
],
"stream": false
}'
Output:
You will receive a JSON response containing details such as the model's output, model name, the number of tokens from the user input, and the number of tokens in the model's output.
Example Output:
{
"id": "6fb162c4-7305-487e-9fad-72a0f92dca0c",
"object": "chat.completion",
"created": 1730969963,
"model": "deepseek-chat",
"choices": [
{
"index": 0,
"message": {
"role": "assistant",
"content": "你好！很高兴见到你。有什么我可以帮忙的吗？"
},
"logprobs": null,
"finish_reason": "stop"
}
],
"usage": {
"prompt_tokens": 11,
"completion_tokens": 13,
"total_tokens": 24,
"prompt_cache_hit_tokens": 0,
"prompt_cache_miss_tokens": 11
},
"system_fingerprint": "fp_1c141eb703"
}
Besides acquiring and testing your API key, consider these factors when developing applications using the DeepSeek API:
| Model | Context Length | Max Output Length | Input Price (Cache Hit) | Input Price (Cache Miss) | Output Price |
|---|---|---|---|---|---|
| deepseek-chat | 128K | 4K (8KBeta) | 0.1 元/百万 tokens | 1 元/百万 tokens | 2 元/百万 tokens |
Tokens are the basic units that models use to represent natural language text, serving as the billing unit. Generally, 1 Chinese word, 1 English word, 1 number, or 1 symbol counts as 1 token.
Note that these ratios may vary due to different tokenization methods across models. Always refer to the usage data in the API response for accurate token counts.
The cost is calculated as:
Cost = Token Consumption × Model Price.
Charges are deducted directly from your recharge balance or complimentary balance, with the latter being used first if both exist.
DeepSeek API doesn't impose strict concurrency limits. However, to maintain service quality during high traffic, you might encounter 429 (Rate Limit Exceeded) or 503 (Server Busy) errors. If this occurs, retry after a short delay. For persistent issues, contact support.
Here are common errors you might encounter:
stream=false), while the web interface uses streaming (stream=true). Enable streaming in the API to improve interactivity.With your Deepseek API Key ready, you can start integrating the API. Refer to these resources for effective usage:
