Common questions

Is CodeGeeX better than StarCoder2-15B for a beginner who just wants help writing code?

Which tool is free?

Both are free. CodeGeeX has a generous free cloud tier; StarCoder2-15B is completely free and open-source, but you pay with your time setting it up.

Can StarCoder2-15B explain code or write tests like CodeGeeX?

Not really. StarCoder2-15B is designed for code generation and completion, not for following instructions or answering questions. CodeGeeX has a chat panel that can explain code and generate tests.

Which tool is better for privacy?

StarCoder2-15B, because it runs entirely on your own computer with no internet needed. CodeGeeX's free tier sends code to the cloud, though it offers a private deployment option for enterprises.
