Github Copilot pro Gives you access to GPT-5.2, Claude Opus 4.5, Gemini 3 Pro for free in VS Code through their 30 day free trial. After that you can choose to pay $10/month, pay for your model usage separately through whatever provider or host you own models

First sign up for Github Copilot Pro free trial
Then go to https://github.com/settings/copilot/features

You must enable access to each model. Yes this is annoying, MS prbl does not want normies getting access to these powerful models, but i’ve spilled the beans :D Enjoy.
Warning / FYI: Copilot Pro includes a limited number of premium requests per month (usage caps apply). The free access is only for one month; after that it’s $10/month, which is a very good deal for access to these models inside VS Code.
