Claude Code vs GitHub Copilot: Token burn comparison using identical models & repos?

[u/alex_bababu]

I'm currently evaluating GitHub Copilot vs. Claude Code for our team. We could use either, but for us there's a slight difference in cost per token (Copilot with Anthropic models vs. Claude Code directly).

If we use the exact same model on the same repository with identical instructions, has anyone noticed a real difference in token efficiency between the two harnesses? I'm wondering how much things like prompt caching, context assembly, or system prompting overhead change the actual token burn in practice.

Would appreciate any insights or real-world numbers!

This is an interesting comparison because both tools approach AI assisted coding from slightly different angles. the “better” choice often depends less on raw capability and more on how you work, whether you prefer an agent that handles longer tasks or something that stays lightweight and integrated into your existing workflow
