Cheap AI Gateway With One API Key for Top AI Models

Looking for a cheap AI gateway that does not make you manage five accounts and five invoices? OpenCheese AI gives you one API key for free models and the newest frontier models from OpenAI, Claude, Gemini, Grok, DeepSeek, Qwen, GLM, Kimi, MiniMax, and more. You can use them to generate code, text, and images.

Plans start at $9.99 per month. You can also start with free models, or use credits with no subscription at all.

Here is the short version. A good cheap AI gateway should be low in price, clear in billing, easy to switch to and careful with your data. This guide shows how OpenCheese AI covers each point, so you can decide in a few minutes.

What Is a Cheap AI Gateway?

A cheap AI gateway is a single access point between your app and many AI providers, offered at prices below the usual list price. You connect with one API key and one base URL. Then you pick the model that fits each task.

This matters because frontier AI is expensive at list price. Separate accounts for every provider make it even harder to control your spending.

What to Check Before You Choose a Cheap AI Gateway

A low headline price is not enough. Before you commit, check these five things:

  • Billing transparency: can you see what every request costs?

  • Model choice: can you pick a cheaper model when the task is simple?

  • Reliability: what happens when a provider fails?

  • Setup effort: do you have to rewrite your code?

  • Privacy: are your prompts stored or used for training?

OpenCheese AI is built around all five.

How OpenCheese AI Keeps Prices Low

OpenCheese AI pays well below list price and passes most of the difference on to you. The savings come from three places:

  • Discounted credits: OpenAI and Anthropic hand out large amounts of API credits through startup, research and promotional programs. Holders often cannot use all of them before they expire. OpenCheese AI buys those unused credits at a discount and spends them on your requests, alongside capacity bought from other providers.

  • Its own servers: some open-weight models, such as Qwen, run on OpenCheese AI’s own servers. There is no provider markup on them.

  • Low overhead: a small team and a company in Nevis, which does not tax income earned outside the federation.

Cheap AI Gateway Pricing Plans

OpenCheese AI has three monthly plans with balance included, plus a no-subscription option.

Squeaky Curd (Pro), mid-temp maturity

  • $9.99 per month

  • $15.00 balance included

  • Suits individual developers, students, and anyone starting to use AI regularly

Aged Gouda (Power), premium for sharp minds

  • $47.99 per month

  • $76.00 balance included

  • Suits freelancers and people who use coding assistants every day

Whole Wheel (Ultra), for startups and vibe coders

  • $99.99 per month

  • $200.00 balance included

  • Suits startups, small teams, and vibe coders who run AI all day

Credit Usage, credits with no subscription

  • $0.00 per month

  • Pay only for the credits you use

  • Suits occasional users and anyone who dislikes monthly commitments

How Much Balance Do You Get for Your Money?

Every subscription includes more balance than its price:

  • Pro: $15.00 balance for $9.99, which is about 50% extra

  • Power: $76.00 balance for $47.99, which is about 58% extra

  • Ultra: $200.00 balance for $99.99, which is about double the price

The higher the tier, the better the ratio. If you already know you will use AI heavily every month, a larger plan gives you the most for your money.

More Ways to Save on AI Costs

Your plan is not the only place where you save:

  • Free models for experiments and prototypes

  • Discounts of up to 95% on working days, and up to 100% at weekends during events announced in the Telegram channel

  • Top-up bonuses, with extra credits on larger top-ups, shown before you pay

  • Pay per request, with tokens and cost for every request visible in your dashboard

Switch in Minutes, Not Days

A cheap AI gateway is only worth it if switching is easy. OpenCheese AI works as a drop-in replacement:

  • OpenAI-compatible: /v1/chat/completions, /v1/responses, /v1/models and /v1/images/* at https://api.opencheese.dev/v1

  • Anthropic-compatible: /v1/messages at https://api.opencheese.dev, the base URL Anthropic SDKs and Claude Code expect

Change the base URL and the API key, and your code stays the same. There are also setup files and guides for Claude Code, Claude Desktop, Codex, OpenCode (with Auto-sync), Zed, Harness AI, VS Code, IntelliJ and LobeHub, plus the mobile apps RikkaHub and Chatbox.

Reliability Without Extra Cost

Every request takes a region-aware path picked fresh for it. If a provider fails or runs out of capacity, the request fails over to a healthy one. New frontier models usually arrive within a day of their release, so you can test them early.

Privacy That Comes With Every Plan

  • No ID documents: sign in with Google, GitHub, Discord, Yandex or Telegram, or with a crypto wallet.

  • Zero training: OpenCheese never trains models on your prompts.

  • No prompt logs: API prompts and responses are not logged or kept. The only exception is a request flagged by the abuse filter. It is kept for review, and its text is erased after 90 days.

  • Short history: transaction history is deleted after 12 weeks.

  • Protected traffic: DNS-over-HTTPS and anti-sniffing protect requests on their way through the gateway.

You can pay with many cryptocurrencies across multiple blockchains, or with a card.

Which Plan Should You Choose?

  • Just exploring? Start with free models and Credit Usage. There is no commitment.

  • Learning or building side projects? Squeaky Curd (Pro) is the lowest-cost monthly option at $9.99.

  • Using AI coding tools daily? Aged Gouda (Power) gives $76.00 balance for $47.99.

  • Running a startup or coding with AI all day? Whole Wheel (Ultra) gives $200.00 balance for $99.99, the best ratio of the three.

You are never locked into one model. Use a premium model when quality matters, and a cheaper or free one for simple tasks.
