The amount of misconceptions in this comment are quite profound.
Copilot isn't an LLM, for a start. You _combine_ it wil a selection of LLMs. And it absolutely has severe limitations compared to something like Claude Code in how it can interact with the programming environment.
"Hallucinations" are far less of a problem with software that grounds the AI to the truth in your compiler, diagnostics, static analysis, a running copy of your project, runnning your tests, executing dev tools in your shell, etc.
>Copilot isn't an LLM, for a start
You're being overly pedantic here and moving goalposts. Copilot (for coding) without an LLM is pretty useless.
I stand by my assertion that these tools are all basically the same fundamental tech - LLMs.
