Integrate DeepSeek AI into IntelliJ IDEA for Smarter Coding

1. Apply for DeepSeek Access

First, request an API key from DeepSeek at https://platform.deepseek.com/usage . After registration you receive a 10‑yuan credit valid for 30 days.

In the "API keys" section, create a new key; note that the key can only be viewed at creation time, so store it securely.

2. Integrate DeepSeek into IDEA

IDEA supports DeepSeek via two plugins: Continue and CodeGPT . Both are easy to install but require a recent IDEA version.

2.1 Continue Plugin

Install Continue via File → Settings → Plugins → Search "Continue" → Install . Then open the plugin’s config button, edit the generated config.json to replace the apiKey with your DeepSeek key.

After configuration, you can invoke DeepSeek in the editor by typing "@" followed by a question, or by selecting code and asking directly.

2.2 CodeGPT Plugin

Install CodeGPT similarly via the Plugins marketplace. Configure it under File → Settings → Tools → CodeGPT . When using the Custom OpenAI mode, set the DeepSeek API endpoint as documented at https://api-docs.deepseek.com/zh-cn/ .

3. DeepSeek Costs

Using the DeepSeek API incurs charges. Pricing details are shown in the screenshot below, and usage statistics can be viewed on the "Usage Information" page, which updates with a minute‑level delay.
