TensorZero reverse-engineered Cursor’s API calls to see its actual prompts and swap models under the hood some interesting stuff in here (check first reply for the link) - step-by-step setup to proxy Cursor through your own gateway (they share the code) - cursor’s surprisingly minimal 642-token system prompts that power the whole experience - discovered cursor uses a “less intelligent apply model” hierarchy for code edits - live a/b testing between claude, gpt-4, gemini while keeping full cursor functionality - you can optimize cursor for your specific coding patterns vs the general population - technical challenges: cursor routes through their servers + electron cors issues they solved
