The DeepSeek API offers a powerful feature called FIM (Fill In the Middle) completion, which allows developers to seamlessly complete content with prefix and suffix inputs. This technique is particularly useful for content generation and code completion. This guide delves into the intricacies of FIM completion, providing a detailed overview, practical examples, and integration tips using DeepSeek's language models.
FIM completion allows users to provide a starting point (prefix) and an ending point (suffix, optional), and the model intelligently generates the content that bridges the gap between them. Think of it as "filling in the blanks" with AI.
Key Features of FIM Completion:
Common Use Cases:
DeepSeek provides excellent support for FIM completion through its API. Here are the key considerations and steps for implementation:

from openai import OpenAI
client = OpenAI(
api_key="<your api key>",
base_url="https://api.deepseek.com/beta",
)
response = client.completions.create(
model="deepseek-chat",
prompt="def fib(a):",
suffix=" return fib(a-1) + fib(a-2)",
max_tokens=128
)
print(response.choices[0].text)
Explanation:
client.completions.create() method sends a request to the DeepSeek API, specifying:
model: Specifies the language model to use (e.g., "deepseek-chat").prompt: The prefix (e.g., "def fib(a):").suffix: The suffix (" return fib(a-1) + fib(a-2)").max_tokens: Limits the length of the generated content.Continue is a powerful VSCode plugin that simplifies code completion tasks. To set it up with DeepSeek:
DeepSeek's FIM completion offers a versatile and powerful method for both content and code generation. Leveraging the strategies and code examples outlined in this guide opens up numerous possibilities for utilizing FIM completion in practical applications. By experimenting with different prompts and parameters, developers can achieve optimal results, streamlining their workflows and enhancing creativity.
