 * AI models like OpenAI’s GPT-4 Code Interpreter are leading this segment.
 * They aid in writing code, offering suggestions, and even generating entire code blocks based on user input.
 * They are particularly beneficial in increasing development speed and making coding more accessible to non-experts.

But they have improved its speed in suggesting entire code blocks and functions right inside the editor. This helps developers generate boilerplate code, complete repetitive tasks and implement common patterns much faster.
