HiveMind reads and edits files, runs shell commands, and reasons about your codebase from the terminal. Every task starts on a cheap model and escalates only when it gets stuck — so you aren't paying top-tier rates for routine work.
Not a pipeline you configure — a loop that closes on itself, and prices itself every time it does.
Every task starts on the cheap default. Prompt prefixes stay byte-stable so most input tokens bill at cache rates, older turns fold into a summary at 75% of the window, andedit_file rewrites only the span that changed.
One request, start to finish
We hold$0.000210
You pay$0.000038
You get back$0.000172
A conservative estimate is reserved before the request is sent, settled down to the real cost when it completes, and returned in full if anything fails — not just the unused part. The running total prints in your terminal after every turn.
Where the cost goes
Three mechanics do most of the work. None of them is a model choice.
Anchored edits
edit_file replaces one old_string with one new_string, so changing a line costs tens of output tokens instead of re-emitting the file. Output is the priciest token class and is never cached — this is the largest single lever on a session.
Prefix cache
Tool schemas serialise in a deterministic order so the prompt prefix stays byte-stable turn to turn. Cache-hit prompt tokens bill at roughly a fiftieth of the miss rate, and the live hit rate prints next to every response.
Four megabytes
One static Rust binary across five targets. No Electron shell, no Node runtime, nonode_modules — curl, then run. It starts in the time a splash screen would have taken.
