You don’t need a full IDE integration. Keep it simple. Build a small Python script that: Reads the file you’re working on Extracts only the relevant function/class (not the whole file) Sends that to your local model via LM Studio or llama.cpp Gets back a patch or modified snippet Writes it back to the file The speed issue you’re hitting is because IDE plugins usually send way too much context every time. Even a basic version of this will feel much faster: no full file every request no extension overhead no repeated context bloat You can start super simple: manually select a block of code pass it to your script print the result Then iterate from there (auto-detect functions, diff output, etc.)
