an experiment in member-owned AI

An AI cooperative.

co/core is a place where people share the compute they already own to run AI for each other, instead of renting from a handful of giant providers. It's an experiment in inference we build, share, and own together — and your existing code works as-is, because we speak the same standard API everything else does. The models are open ones that run on the hardware people already have.

Real members. Real machines. Real receipts.

A glimpse of the co-op right now — some of the people who've signed up, some of the machines sharing compute, and the latest jobs they've signed off on. Every one of these is a real, public record.

co/core speaks the same API language as everybody else. Point your existing SDK at cocore.dev/v1, drop in a cocore-… key, and keep going — streaming, tool calls, and the usual chat/completions shape all work, no code changes. Host from our presets or any MLX model.

02 how it works

You send a request. The co-op runs it.

Your request finds a member's available compute, runs the job, and comes back to you. The whole thing is an open spec — every job leaves a signed, public record anyone can verify for themselves, ours included.

1job

You send a job

Your encrypted prompt heads out into the co-op. Run your prompt for a given model anywhere in the open network, or choose to keep your jobs private to only a trusted circle of co-op friends and their machines.

2attest + run

A member runs it

Someone picks up your job, runs it, then returns the result after signing with a key held in the Secure Enclave that never leaves their hardware — evidence of who did the work, and a check that the result wasn't altered afterward.

Receipts, in the open

A receipt closes out the job — credits go to whomever who ran it, minus a small cut to a shared pot. Each month that pot splits back to members by how much they pitched in, so the cut cycles right back to the people running the network.

You don't have to take our word for it.

Every job writes a receipt anyone can verify on their own, without ever calling us. We can't inflate a balance, fake a payout, or quietly change the rules. And if you don't like how we run things, you can run the whole thing yourself — point your own copy at the same data and it lands on exactly the same numbers.

The record lives with the person who made it
We keep a fast index, but the real, signed record of every job lives on the provider's own account — not locked inside our database.
Receipts check out on their own
A receipt plus our public spec plus the signer's identity is all you need to confirm a job happened — offline, with no co/core API in the loop.

04 an open standard

An open standard. Run your own exchange.

Underneath the co-op is an open standard for two plain things: making an inference request, and recording what happened afterward — a signed, public account of every job. We run one exchange on top of it, with our rules: one unit in, one unit out, a shared pot that goes back to members. But the standard is the real work here. Anyone can stand up a different exchange — their own pricing, their own membership, their own idea of what's fair — reading and writing the very same records. Ours is just the first one. If co/core ever stops being the version you want, you don't have to ask us to change it; you can go build yours.

share your compute

Share your compute. Help run the co-op.

Download the co/core app, sign in, pick a model or two, and your computer joins the network — running jobs for other members while you're not using it. No Terminal, nothing to babysit; it updates itself. Every job it runs adds to your balance, and a share of everything the co-op does comes back to members each month.

Your machine, your key
A key born inside the Secure Enclave is your machine's identity — it can't be copied off the machine, and it signs everything your machine does.
One token in, one token out
The same price for everyone, set in the open. Every job moves tokens three ways: the requester spends, your machine keeps 95%, and 5% goes to a shared pot that goes back to members every month.
Run your own jobs free
Serving a job to yourself costs no fee — but it still writes a receipt, so the trail stays complete.
