Real‑world video demo: Using different AI models in GitHub Copilot

GitHub Copilot offers a range of generative AI models to assist developers with coding tasks, providing three distinct modes—ask, edit, and agent—to accommodate different workflow needs. In a video collaboration with GitHub Developer Advocate Kedasha Kerr, the capabilities of these modes were explored by building a simple travel-reservation app using different foundation models. The demonstration highlighted that context and prompt shaping are crucial for optimal performance, with agent mode enabling more autonomous, project-wide tasks. Custom instructions can further tailor Copilot's behavior, ensuring consistent and secure code output across models. Despite the variety of available models, choosing the right one depends on the specific needs of the task, balancing speed and output quality. The session encourages developers to experiment with multi-model workflows and customize their use of Copilot to maximize efficiency.
