Hi everyone 👋 Pi is a terminal coding agent we use every day. Like most JavaScript tools, it pays a startup cost each time you launch it: the runtime parses, interprets and JIT-compiles the code before you can type. Long sessions cost more too, because the whole answer is redrawn as each few words stream in. Pi-Bolt does that work once, when it's built. We took the ahead-of-time compiler for JavaScriptCore from oven-sh/WebKit#743, ported it to x86-64 and macOS, and used it to compile every function in Pi to machine code. Pi's modules are stored in the executable already loaded, so at launch it maps the file and runs. Compared with Pi on Bun 1.4.2: • Ready to type in 45 ms instead of 128 ms on Linux, and 31 ms instead of 63 ms on an M5 Mac • About a third of the CPU over an interactive session • 11× less CPU streaming a long answer, and a 200 KB file written in 0.8 s instead of 27.8 s It's still Pi. The commands, keys, sessions and extensions are the same, and it shares ~/.pi/agent, so your logins are already there. It doesn't need Node or Bun. curl -fsSL https://pi-bolt.opensec.in/insta... | sh or: npm install -g pi-bolt The repo has every benchmark with its method and raw data, plus all the engine patches. Windows and Linux on ARM aren't supported yet, so tell us which one you'd want first. Pi-Bolt is an independent fork. Thanks to Mario Zechner and Pi's contributors, and to Oven for Bun. We'd love to hear how it runs on your machine.
