A deliberately tiny VS Code extension that provides inline autocomplete suggestions with DeepSeek's Fill-In-Middle completion API.
Features
- TypeScript extension code.
- VS Code inline completions at the cursor.
- Status bar indicator that spins while DeepSeek requests are in flight.
- Prefix and suffix context sent to DeepSeek FIM.
- Simple JSON settings for API key, model, base URL, token limit, temperature, trigger mode, timeout, and context size.
- Unit tests for the core request/config/context logic.
Settings
Add these to your VS Code settings.json:
{
"deepseekFimAutocomplete.apiKey": "YOUR_DEEPSEEK_API_KEY",
"deepseekFimAutocomplete.model": "deepseek-v4-pro",
"deepseekFimAutocomplete.baseUrl": "https://api.deepseek.com/beta",
"deepseekFimAutocomplete.maxTokens": 128,
"deepseekFimAutocomplete.temperature": 0.2,
"deepseekFimAutocomplete.triggerMode": "automatic"
}
Set deepseekFimAutocomplete.triggerMode to manual if you only want requests when running DeepSeek FIM: Trigger Inline Completion. The default keybinding is Ctrl+Alt+Space (Cmd+Alt+Space on macOS).
