GitHub has announced the launch of a free plan for its Copilot service, which provides 2000 Code Completions per month and 50 chat messages, utilizing the GPT-4 and Claude 3.5 Sonnet models. This free plan is a more affordable alternative to the paid subscription options, which offer more features and benefits. The free plan is available for anyone to use, and it can be accessed through the GitHub website. This move by GitHub is aimed at making copilot more accessible to developers and businesses, and it is expected to increase the adoption of the AI-powered coding assistant. For more information about the free plan and the paid subscription options, please visit the GitHub website.
