If you use LLMs for work, study, or hobby, the token bill can be a nasty surprise. The thriftllm 0.0.0 project, released on PyPI on October 5, 2026, offers an approach to control costs: routing requests between models based on real cost and quality. But to make this tool work, you need to pay for access to LLM providers. Here's how to do it from Russia without overpaying.

What is cost-routing and why you need it

ThriftLLM is a library for routing requests to large language models. It forecasts output length, accounts for caching and tiered pricing, then selects the model with the best price-to-quality ratio. Essentially, you don't pay for an expensive model when a cheap one will do.

The tool is useful for developers who run thousands of API requests daily. But it doesn't eliminate the need to pay for API keys from OpenAI, Anthropic, Google, or other providers.

How much popular LLM services cost (as of October 2026)

Prices change often, so always check current rates on the provider's website before paying. Below are reference points to help you plan your budget.

  • OpenAI (ChatGPT Plus / API): Plus subscription is about $20/month; API is billed per 1K tokens, price depends on the model (GPT-4o, GPT-4o mini, etc.).
  • Anthropic (Claude Pro / API): Pro subscription is about $20/month; API starts at $0.25 per million input tokens for smaller models.
  • Google Gemini (AI Pro / API): Subscription is about $20/month; API has a free tier, then paid.
  • OpenRouter: A model aggregator, pay-as-you-go, top-up from $5.

Prices are in USD and may include taxes. Use the calculators on the services' websites for exact calculations.

Which cards LLM services accept

Most foreign LLM providers accept Visa and Mastercard issued in any country except sanctioned ones. However, Russian Visa/Mastercard cards issued by local banks don't work due to disconnection from international payment systems. Mir cards are not accepted.

Regional restrictions: some services block access from Russia by IP, so a VPN may be required. Also, OpenAI and Anthropic don't serve users from certain countries — check the terms.

How to pay for an LLM service with a virtual card: step by step

  1. Choose a virtual card service. Make sure the card is issued in USD or EUR and supports payments to foreign services. For example, VirtCardPay lets you issue a card in minutes.
  2. Top up the balance. Calculate the amount with a buffer: subscription + possible conversion fee. For a $20 subscription, keep $25–30 on the card.
  3. Link the card in your LLM service account. Enter the number, expiry date, and CVV. Ensure the cardholder name matches the service data (sometimes required).
  4. Make a test payment. Some services charge $1 to verify the card — this is normal.
  5. Watch the billing date. Subscriptions usually auto-renew. Top up 2–3 days before the charge to avoid decline.

What to do if a payment is declined

  • Check the balance — you might not have enough funds.
  • Make sure the card is active and not expired.
  • Contact virtual card support — sometimes the issuing bank blocks suspicious transactions.
  • Try another card or payment method (e.g., PayPal if available).
  • If the service doesn't accept cards from your region, consider paying with cryptocurrency (USDT) — some LLM platforms accept crypto.
