Pick your AI. Then put it to work properly.
These are the AIs the harness works with. The harness doesn’t run a model for you — you sign up with the AI you like, then bring your prompt back here and run it under discipline: a frozen checklist, a second check, one bounded fix round.
Start with the one behind this site
Muse (Meta AI) is the assistant James uses to build and run this site — it built the game in the tutorial from one refined prompt. If you want the same setup, start there.
Muse is a separate product (Meta AI) — it’s the assistant James uses to build and run this site; this site isn’t Muse. His invite code is 2LZAND: after joining Muse, enter it in the app under Settings → Redeem token (within 48 hours of joining), or on the web under Settings → General → Usage → Redeem invite code. The offer terms themselves are on Muse’s own screens.
Every other AI, one tap away
Already have a favorite? Any of these works with the harness — the discipline travels with the prompt, not the model. Each pill goes straight to that service’s own sign-up page.
That’s 25 in all, counting Muse above. Bounded Agent Harness isn’t affiliated with any of them — the links are plain signposts, and each service’s own terms apply over there.
