Connect your GPU and get paid for real workloads

Contributor AI turns your spare compute into income. You stay in control of when the worker is online, which GPUs are used, and can stop at any time.

Step‑by‑step

  1. 1. Sign up as a contributor. Choose “Contributor (have GPU)” on the sign‑up page.
  2. 2. Install and log in via CLI.
    npx @contributor-ai/client login
  3. 3. Start the worker. The worker will poll for tasks and execute them in containers.
    CONTRIBUTOR_API_URL=https://gpugrid.duckdns.org npx @contributor-ai/client run
  4. 4. Track jobs and payouts. Use the web dashboard to see active jobs, history and earnings.

Simple earnings estimator (rough, not a guarantee)

Client pays competitive rates (aligned with Vast.ai, RunPod). You receive 90%; platform keeps 10%.

Estimated monthly gross (after 10% platform fee): $178.20 USD

Client pays $0.55/hr → you receive $0.50/hr (90%).

360 GPU‑hours × $0.50 / hour.

Actual earnings depend on demand, job mix and uptime. Prices aligned with Vast.ai, RunPod and Lambda Labs.

For contributors — connect your GPU PC

  1. 1. Requirements

    Windows or Linux, NVIDIA GPU 8GB+ VRAM, Python 3.11–3.12, Node.js 18+, Tailscale on VPS and PC.

  2. 2. Install ACE-Step on your PC

    Clone github.com/ace-step/ACE-Step-1.5, run uv sync, set ACESTEP_API_KEY, start: uv run acestep-api (listens on :8001).

  3. 3. Tailscale

    Install Tailscale on PC and server, same account. Note your PC Tailscale IP (e.g. 100.x.x.x). Platform admin sets ACE_STEP_REMOTE_URL=http://YOUR_IP:8001 on the server.

  4. 4. Sign up & CLI

    Register as Contributor. Then:

    CONTRIBUTOR_API_URL=https://gpugrid.duckdns.org npx @contributor-ai/client login
CONTRIBUTOR_API_URL=https://gpugrid.duckdns.org npx @contributor-ai/client run
  5. 5. On the GPU machine

    Set ACE_STEP_REMOTE_URL=http://127.0.0.1:8001 and the same ACE_STEP_API_KEY before running the client. Worker runs ACE-Step for ace_step_audio tasks.

Windows quick start

  • Download contributor-setup.bat and contributor-run.bat from the contributor dashboard.
  • Run setup.bat once — enter contributor email/password.
  • Keep ACE-Step API running, then run contributor-run.bat.

FAQ

Why does the site say Remote GPU offline?
ACE-Step is not running on the PC, or Tailscale is disconnected. Start acestep-api and check Tailscale on both devices.
Do I need a contributor if the platform has remote GPU?
Jobs can run on the platform's connected PC automatically. Contributors are for extra capacity and other machines.
What task types are supported now?
Audio generation with lyrics via ACE-Step (ace_step_audio). More GPU task types coming later.

Requirements & safety

  • • Stable internet connection and recent NVIDIA GPU with updated drivers.
  • • We recommend running on a dedicated machine (not your primary daily‑use PC).
  • • Jobs run in containers; by default they only see a working directory you configure.
  • • You can stop the worker at any time — tasks will be rescheduled to other contributors.
