Step-by-Step Guide: From Registration to Activation​

1. Register an account on the AI platform
   Follow this link. The platform combines Opus 4.7, GPT-5.5, and dozens of other top-tier models in one interface. You will need to:
   • Use any email (Gmail, Yandex, Mail.ru — it doesn't matter);
   • Create a password;
   • Verify your email (a standard email with a verification button).
   • Registration takes less than a minute.
2. Link your GitHub account
   This is a mandatory requirement — the platform uses GitHub for verification to ensure you are not a bot and have a basic connection to development. If you don't have a GitHub account yet — create one (it's free, github.com), and then in your profile settings, click "Connect GitHub". The system will ask for authorization — confirm it. You won't be able to proceed without this step.
3. Change your billing plan
   In the bottom left corner, go to Settings → Billing → Change Plan. Choose the very first paid tier from the list — it typically costs $20/month and includes access to Opus 4.7, GPT-5.5, etc. Don't worry — there will be no actual charges.
4. Generate a virtual bank card
   Now we need a "throwaway" card that will pass the validity check. Open the card generator website. In the BIN field (the first digits of the card), enter:
   

   623358637xxxxxxx

   This BIN matches a US bank debit card and is compatible with our platform's billing. Generate the card — you will get:
   • Full card number (16 digits);
   • Expiration date (MM/YY);
   • CVV (3 digits on the back).
   • Tip: If one card doesn't work, just click "Generate" again to get fresh details.
5. Link the card to your AI account
   Go back to the AI website, navigate to the Billing section (or the payment form will pop up automatically). Select "Credit/Debit Card" as your payment method and fill out the fields:
   • Card Number: 16 digits from the generator;
   • Expiration Date: month/year from the generator;
   • CVV: 3 digits from the generator;
   • Country: United States (mandatory);
   • Postal Code (ZIP): 10001 (New York, works reliably);
   • You can leave the rest of the fields (Street, City) blank or enter whatever you want.
6. Activate the subscription for free
   Click Submit / Confirm Payment. The system will verify the card (an authorization hold usually occurs), and if everything is correct, the subscription will become active. No real money will be charged!
7. Congratulations — you now have Premium access to Opus 4.7 and GPT-5.5 at absolutely no cost.

Frequently Asked Questions (FAQ)​

— How long does the subscription last?
14 days from the moment of activation.

— The card is being declined, what should I do?

• Try generating a new card with the same BIN (refresh the CVV and expiration date);
• Make sure you have selected Country: United States and ZIP: 10001;
• Change the card generator — sometimes anti-fraud systems flag a specific site;
• Double-check that your GitHub is linked — the payment will fail regardless if it's not.

— Is this legal?
This method exploits a vulnerability in payment detail verification. Use it only for educational purposes and temporary access. Continuous use may violate the service's Terms of Service. All responsibility lies with you.

— What other AI models does this subscription unlock?
Usually, the $20 tier includes all top-tier models: Claude (Opus), GPT, Grok, Kimi, and others.
