Updated on weekdays
Free API credits for AI models, in one place.
A daily-updated list of sites that give free LLM API tokens — with what you get, whether they work like OpenAI, and the base URL you need.
…providers listed
…last checked (IST)
Figures come from each provider’s own pages on the date shown, and they change often. Check before you rely on them. Never share your API keys.
Get your API key
Copy the key from their dashboard and keep it secret — on your computer or in an environment variable, never in a public chat or repo.
Set the base URL
Point the OpenAI SDK (or any OpenAI-compatible client) at the provider’s base URL:
import OpenAI from "openai";
const client = new OpenAI({
apiKey: process.env.API_KEY,
baseURL: "https://api.example.com/v1",
});

Common questions
What does OpenAI compatible mean?
You can use the official OpenAI SDK or any client that talks to OpenAI’s API. Just change the base URL and use the provider’s API key. “Partial” means only some features or models work that way.
What are tokens per day?
A token is a small chunk of text the model reads or writes — a few characters or a short word. The daily figure is the provider’s published free limit, when they publish one. If they do not, we show “Not published” rather than guessing.
What does the relay warning mean?
Those sites are unofficial gateways or resellers. They forward your prompts to other providers. Do not send private or sensitive data through them.
Do I need a credit card?
It depends on the provider. Use the “No card needed” filter to narrow the list, then confirm on their site — some ask for a card later, or after a trial credit runs out.
Why does it say “Not published”?
The provider has not published that figure on their public pages. We never invent quotas, prices or endpoints.
How often is this list updated?
On weekdays. The “last checked” time at the top is when the list was last reviewed, shown in India Standard Time (Asia/Calcutta).
