Browser worker quick start

Turn your browser tab into a GPU worker and start earning USDC. No installation required.

Setup​

  1. Go to genkaku.app/earn
  2. Log in with your X (Twitter) account
  3. On a laptop, point Chrome at your real GPU first. Open chrome://flags/#force-high-performance-gpu, set it to Enabled and restart the browser. On Windows laptops Chrome generally runs on the integrated GPU, and a page asking for a high-performance adapter does not change that — so without this flag a machine with a discrete card can end up doing all the work on integrated graphics, many times slower.
  4. Browser workers run Qwen3.5 Uncensored and serve the browser lane (genkaku-pro requests and free prompts). Your tab picks the size it can hold: 9B (~5.1GB download, needs ~6.4GB VRAM) on a card with the room, 4B (~2.4GB download, needs ~4GB VRAM) otherwise. There is nothing to choose.
  5. Click Start Worker

The first time you start, the model downloads to your browser's cache. This takes a few minutes depending on your connection. After that, subsequent starts are instant.

Running​

Once the model is loaded, your browser is actively processing jobs from the GenKaKu. The worker page shows real-time stats:

  • USDC earned — your total claimable earnings
  • Uptime — how long the worker has been running
  • Jobs completed — number of inference requests processed
  • tok/s — your current token generation speed

Keep the tab open and active. If you close it or navigate away, the worker stops.

Tips​

  • Use Chrome or Edge — they have the best WebGPU support
  • Don't minimize the tab — some browsers throttle background tabs, which kills performance
  • Check your GPU — open chrome://gpu to verify WebGPU is enabled and using your discrete GPU
  • A second tab fits on a large card, but don't count on it — a 9B worker needs about 6.4GB (weights, KV cache at 4k context, and workspace), so a 24GB card has room for three. They still share one GPU, and we have not measured whether two tabs together out-earn one. On an 8GB card there is only room for one.

Requirements​

  • A browser with WebGPU support (Chrome 113+, Edge 113+, Firefox 130+ with flag)
  • A GPU with ~4GB free VRAM to run Qwen3.5 4B Uncensored, or ~6.4GB (RTX 3060+, M1+, etc.) to run the 9B

Earnings​

Workers earn 70% of the USD value of the credits spent on every job they complete, paid out in USDC. Earnings depend on:

  • Tokens generated — longer responses spend more credits, so they earn more
  • Availability — workers who stay online longer get more jobs

Stake to earn more. Workers who stake at least 500,000 $ZERO (held 24h) earn an 80% share instead of 70% on every job. See Staking.

Earnings are tracked on the worker page and tied to your account. Withdraw your balance to any Solana wallet as USDC whenever you like.
