If you use your own API key, we do not collect or store any of your data.
If you do not provide an API key, the fsiovn FIM (Fill-in-the-middle) endpoint will be used by default.
The fsiovn FIM endpoint is only allowed to be used with the AI Autocomplete extension so all other uses are prohibited.
The fsiovn FIM endpoint may collect and store data so use your own API key if you're concerned about privacy.
We disclaim all responsibility.
Compare with GitHub Copilot
GitHub Copilot remains a more full-featured product overall.
Pros:
Web support:
GitHub Copilot still doesn't fully support VS Code for the Web (github.dev, vscode.dev).
This extension works seamlessly in web environments, making it ideal for contributing to public repositories without a local setup.
Lightweight:
This extension is extremely small - around 40 KB, compared to 33 MB for GitHub Copilot + Copilot Chat.
Focused on autocomplete:
The extension is dedicated purely to autocomplete.Users who prefer external chat tools (Cline, KiloCode, ClaudeCode, Codex CLI, etc.) can combine them as they like.
Privacy-friendly (BYOK):
When users bring their own API key, the extension does not collect or store any code or usage data.
No additional subscription needed:
Users with a Cerebras Code Pro/Max or Gemini subscription don't need a GitHub Copilot plan.
Better free tiers:
Cerebras and Gemini both offer more generous free tiers compared to GitHub Copilot's current free tier.
Cons:
Copilot is generally more capable overall:
While inline suggestions work similarly, GitHub Copilot tends to perform better in certain scenarios - especially with more advanced features like Next Edit, multi-file reasoning, and deep context understanding.
No built-in chat:
Unlike Copilot Chat, this extension intentionally does not include an integrated chat experience (though users can combine it with third-party tools if needed).
Model quality depends on user's API key provider:
Performance will vary depending on whether users choose Cerebras or Gemini and what tier they're on.
Overall, GitHub Copilot remains a more comprehensive solution, but this extension focuses on being lightweight, open-source, and flexible.
