Pricing FAQ

How does Mentat differ from GitHub Copilot?

Mentat focuses on coordinated multi-file editing from the command line, while Copilot provides inline suggestions within IDEs. Mentat understands entire project context and implements complex changes across multiple files simultaneously.

What are the costs associated with using Mentat?

Mentat itself is free and open-source, but requires OpenAI GPT-4 API access which charges based on token usage. Costs depend on project size and frequency of use.

Can Mentat work with large codebases?

Mentat is limited by GPT-4's token context window, so it works best when focused on specific files or directories rather than entire large codebases at once. You can target specific areas for optimization.

Is my code secure when using Mentat?

Mentat processes code locally and only sends necessary context to OpenAI's API for processing. The open-source nature allows full security auditing, and no code is permanently stored on external servers.

What programming languages does Mentat support?

Mentat supports any programming language that GPT-4 can understand, which includes most popular languages like Python, JavaScript, TypeScript, Java, C#, Go, Rust, and many others.
