Start with a provider
The same model family can be offered by several providers, with different account rules and quotas. These starting points link to official key creation and access information.
Featured in the model directory
One API key can reach models from multiple providers. The CheapOS model directory currently lists OpenRouter routes, so this is the most direct path from a listing to a request.
Direct provider access
Create a Gemini API key in AI Studio. Google says new users get a project and key, and the Gemini API free tier covers selected models.
Direct provider access
Create a key in the Groq console and use its hosted model API. The free plan publishes limits that differ by model and usage window.
From key to first request
Compare the model's listed price and supported features. Then check its provider's current quota, account requirements, and terms.
Browse model routes →Use the provider's official dashboard. A free model price does not guarantee unlimited access or mean every account requirement is free.
Add the provider credentials to the supported local gateway or client. For CheapOS setup, follow the model connection guide; keep the key out of project files and public chats.
Read the CheapOS connection guide ↗Free has more than one meaning
A provider key is an identity credential, not a promise of free usage. A model can have a zero token rate while the provider still applies sign-up rules, quotas, feature charges, or terms for personal and commercial use. These details can change, so confirm them at the linked provider before sending important data or relying on a quota.
No. The price is one part of access. The provider may apply account, quota, concurrency, feature, or availability limits.
No. Create keys directly with each provider. Never share a private key with this site or post it in a public repository.
Not yet. The current price catalog covers OpenRouter routes. We label the other providers as key and access guides until their models and published prices are represented separately.
