You can use local models with most of those, you’d just need to get something like Ollama, LM Studio or vLLM working - but that’s the boring and not flashy part, it’s probably easier to name the dev tools.

Copilot: https://docs.github.com/en/copilot/how-tos/copilot-cli/custo... (also worked in Visual Studio Code)

Claude Code: https://code.claude.com/docs/en/model-config (here’s an example of a custom config in the wild with DeepSeek, same principle for local connection https://api-docs.deepseek.com/guides/agent_integrations/clau...)

Cursor: couldn’t find official docs but here’s z.AI docs https://docs.z.ai/devpack/tool/cursor (same principle for local API)

And you better be sure that I'm setting up linux on this. Windows is not the ideal platform for anything anyway.

Nitpick, but I remember running it specifically because there was a way to run LLMs on local hardware.
