VSCode with Claude Code or GitHup Copilot

Overview: I have seen people really struggling with understanding that Claude is not GitHub Copilot (GHCP).  And GitHub Copilot is not an LLM. 

Terminology: 

Claude by Anthropic is made up of various parts, and it helps to be more specific.  Calusde is amazing at providing great Large Language Models (LLMs).  There are Claude Opus (for programming the lastest us 4.7), Claud Sonnet, and Claude Haiku.  GPT-5.4 is OpenAI's current flagship LLM.  Gemini 3.1 Pro is known for UI-focused coding. I found Gemini 3.0 good, but I don't use it that often.   

Claude also offers other services beyond supplying LLMs like Claude Code and Claude CLI.  These are the key ones for me:

Claude in Chrome — a browsing agent

Cowork — a desktop tool for non-developers to automate file and task management, rival to Microsoft 365 Copilot.

GitHub Copilot for VS Code is the equivalent of Claude Code for VS Code

Developing in VS Code:

In the screen below, I am using both Claude Code and GitHub Copilot in the VS Code IDE.

Here I have some C# code that creates and deploys an Azure Function. I can use either option until I run out of credits with my monthly (GHCP) or hourly (Claude) subscription allowance.  When I go over my GHCP allowance, I have it set up to use my Azure Credits.
