How to Integrate DeepSeek‑V3 AI into PyCharm Using the Continue Plugin

Overview

DeepSeek is a Chinese AI company; its latest model DeepSeek‑V3 offers performance comparable to top international models such as GPT‑4o.

Integrating DeepSeek into PyCharm

First, obtain an API key from the DeepSeek website ( https://www.deepseek.com/ ) and the API Open Platform.

Then install the Continue plugin in PyCharm (File → Settings → Plugins → search “Continue” → Install → Apply).

Open the Continue tab, click the settings button, and replace the default configuration file with the following JSON:

{
  "completionOptions": {
    "BaseCompletionOptions": {
      "temperature": 0.0,
      "maxTokens": 256
    }
  },
  "models": [
    {
      "title": "DeepSeek",
      "model": "deepseek-chat",
      "contextLength": 128000,
      "apiKey": "REDACTED",
      "provider": "deepseek",
      "apiBase": "https://api.deepseek.com/beta"
    }
  ],
  "tabAutocompleteModel": {
    "title": "DeepSeek Coder",
    "model": "deepseek-coder",
    "apiKey": "REDACTED",
    "provider": "deepseek",
    "apiBase": "https://api.deepseek.com/beta"
  },
  "customCommands": [
    {
      "name": "test",
      "prompt": "{ { input }}} Write a comprehensive set of unit tests for the selected code. It should setup, run tests that check for correctness including important edge cases, and teardown. Ensure that the tests are complete and sophisticated. Give the tests just as chat output, don't edit any file.",
      "description": "Write unit tests for highlighted code"
    }
  ],
  "contextProviders": [
    {"name":"diff","params":{}},
    {"name":"folder","params":{}},
    {"name":"codebase","params":{}}
  ],
  "slashCommands": [
    {"name":"share","description":"Export the current chat session to markdown"},
    {"name":"commit","description":"Generate a git commit message"}
  ]
}

Replace the placeholder REDACTED values with the API key you saved earlier, then save the file.

After restarting PyCharm, you can select code, press the Continue shortcut, and the model will explain or modify the selected snippet.
