Frequently Asked Questions
5 questions
It depends on your needs. Copilot justifies its cost for enterprise teams and professional developers due to 85% accuracy (vs 76%), deeper IDE integration (15 vs 12), and GitHub workflow optimization. However, individual developers and open-source contributors get equal or better value from Codeium's unlimited free tier, which has faster response times (1.2s vs 2.1s) and newer training data (August 2024 vs April 2024).
