There is also a separate coding-specific chatbot offered by OpenAI.
Claude (Anthropic)
In combination with ChatGPT, one of the most popular models known for its excellent reasoning and performance quality with exceptional writing quality and coding capabilities due to the wide context window.

Copilot (Microsoft)
