I use Emacs for most of my work related to coding and technical writing. I've been running phind-v2-codellama and openhermes using ollama and gptel, as well as github's copilot. I like how you can send an arbitrary region to an LLM and ask for things about it. Of course the UX is in early stage, but just imagine if a foundation model can take all the context (i.e. your orgmode files and open file buffers) and can use tools like LSP.
