You do research in math, physics, cryptography or quantum computing. Quantum Compute gives you real quantum hardware with $50 of free credit every 90 days. Enigma and conjectures pay prizes for solving hard problems.
Runs jobs on IonQ, Rigetti, IQM and AQT quantum computers through one API, with $50 free every 90 days.
First stepRun a small Qiskit circuit with the free credit.
Access runs through partner Open Quantum; we didn't check its own sign-up page.
Prize rewards for checked Lean proofs or counterexamples to famous open conjectures.
First stepBrowse the open conjectures and pick one in your field.
Fees go by hand-confirmed treasury transfer for now; card and USDC payment are planned.
Funded prize challenges in cryptography, quantum computing and AI.
First stepRead the current challenges before buying any submission credits.
Submission credits are bought by card through Open Quantum or paid in the subnet's token; current prize amounts weren't shown.
Rent NVIDIA GPUs by the hour to train or run AI models.
Prices are hourly and shown live, but the site doesn't say which payment methods it takes.
Train your own AI models across many scattered machines, either yourself with an SDK or managed.
No pricing or sign-up is described; the managed option starts by emailing the team.
A privacy network and VPN app that encrypts your internet traffic on phone and browser.
The site doesn't state prices or payment methods; there's a 'Buy data' page we didn't verify.
Tests your image AI model with tricky inputs and sends a report on where it breaks.
Only image classification models are supported now, the Pro plan is early access and orders go through a contact form.
Spots deepfakes and AI-generated content so you can check it before you trust or share it.
There's no public pricing page; paid API and enterprise pricing go through sales.
Rent cloud GPUs by the hour, from RTX workstation cards to H100s and B200s.
Prices vary by listing, and accepted payment methods aren't stated.
No for Quantum Compute and Enigma, which are free to start or take normal payment. conjectures needs TAO or another crypto token.
Bittensor is a network of 128 subnets. Each one is a competition where miners do a job, like serving AI models or renting out GPUs, and validators score the work. Some subnets also sell what they produce as a normal product. This guide only recommends those.
