Access every AI model without a subscription — from anywhere in the world
Reach every frontier model — GPT, Claude, Gemini, DeepSeek and more — in one place. No subscriptions, no accounts, pay per prompt in USDC, from anywhere.
The best model changes by the task. Some days you want GPT, some days Claude, some days Gemini, DeepSeek, Llama, or Qwen. Getting to all of them today means stacking up subscriptions — and if you happen to live in the wrong country, you may be locked out of the good ones entirely.
There’s a simpler way: one place, every model, pay per prompt, from anywhere in the world.
The problem with the subscription model
Reaching the frontier through subscriptions is quietly broken:
- You pay for several, and still can’t reach everything. ChatGPT Plus gets you OpenAI’s models. Claude Pro gets you Anthropic’s. Another plan for Google’s. Three subscriptions, three walled gardens — and you’re paying flat monthly fees whether you use them or not.
- Accounts, cards, and verification. Each provider wants a sign-up, a payment method it accepts, sometimes a phone number — friction before you’ve asked a single question.
- Region locks. This is the big one. The leading assistants are unavailable or restricted across much of the world. If your country isn’t on the list — or your card isn’t accepted — you’re out, no matter how much you’re willing to pay. People resort to VPNs and borrowed cards just to reach a model.
- Rate limits and lock-in. Hit a cap and you wait. Want to switch models mid-task? Different app, different login.
You end up paying more to reach less, and where you live can decide whether you get access at all.
Halo: one place, every model, pay per prompt
Halo is a peer-to-peer marketplace for AI inference. Instead of subscribing to each provider, you reach every model on the network from one place and pay only for what you use.
- Every major model, one endpoint. 160+ models across providers — OpenAI, Anthropic, Google, DeepSeek, Qwen, Llama, Mistral, and more — available through the same app. Pick the right model per task without switching accounts. (Browse the live list at app.runhalo.xyz/models.)
- No subscription — pay per prompt. You’re billed per request in USDC on Base, for the actual tokens you use. No monthly fee, no minimum, nothing wasted on a plan you barely touch.
- No accounts, no API keys. A wallet is your login. Fund it once, and you’re prompting — no sign-ups, no provider approval.
- Works anywhere. This is the point. Halo is permissionless and censorship-resistant: if a model is blocked or unavailable where you are, another operator on the network can serve it to you. There’s no single company — and no region list — standing between you and the model.
- Private when you need it. For sensitive work, confidential mode runs your prompt inside a hardware enclave the operator can’t read, with proof your browser verifies.
It’s the practical answer to “is there a ChatGPT alternative that gives me all the models, without a subscription, that works in my country?” — yes.
Subscriptions vs. pay-per-prompt
| Provider subscriptions | Halo | |
|---|---|---|
| Models | One provider’s lineup per plan | 160+ across every major provider |
| Cost | Flat monthly, per provider | Pay per prompt, only what you use |
| Sign-up | Account + card + verification, each | A wallet — no accounts, no API keys |
| Where it works | Region-locked, card-dependent | Anywhere with internet + a wallet |
| Switching models | Different app/login each | Same place, pick any model |
| Privacy | Trust the provider | Optional hardware-enclave (TEE) mode |
How to start
You can be prompting in a couple of minutes:
- Open the app and connect a wallet.
- Fund your balance with USDC on Base (a little ETH covers the one-time deposit; after that, gas is sponsored).
- Pick any model and go.
Full walkthrough: use Halo on the web, and fund your account covers the wallet + balance in detail. Prefer to drive it as an agent? See chat vs agent mode.
FAQ
Do I need a subscription? No. You pay per prompt in USDC for what you actually use — no monthly plan, no minimum.
Which models can I access? 160+ across OpenAI, Anthropic, Google, DeepSeek, Qwen, Llama, Mistral, and more — all from one app. The live list is at app.runhalo.xyz/models.
Can I use it in my country? If you have an internet connection and a wallet, yes. Halo settles on-chain and routes around blocks, so access isn’t gated by region or by which cards a provider accepts.
Do I need crypto experience? Just a wallet and some USDC on Base. No API keys, no provider accounts — the wallet is your identity and your budget.
Is my prompt private? By default it’s end-to-end encrypted to the operator. For anything sensitive, turn on confidential mode and it’s sealed to a hardware enclave even the operator can’t read.
Stop renting three walled gardens and hoping your country’s on the list. Reach every model from one place, pay for exactly what you use, and do it from anywhere.
