Why "unlimited" free AI doesn't exist
Every free tier is paid for by the provider, so every one is capped. The caps come in three shapes:
- Requests per minute: a burst limit, typically 10 to 60. It resets every minute.
- Requests or tokens per day: the cap most free tiers use. It resets daily, forever, with no card.
- Monthly token pools: a fixed allowance shared across a provider's models.
Anything advertised as unlimited and free is usually a time-limited trial, a shared key that gets revoked, or a resold account that breaks the provider's terms. None of those keep working.
The closest real thing: stack the free tiers
Each provider's limit is separate, so they add up. The largest free pools in the catalog right now, as each provider publishes them:
| Provider | Free allowance | Example model | Request limits |
|---|---|---|---|
| NaraRouter | free · 7M/day shared | Agnes 2.5 Flash (NaraRouter) | 10 rpm |
| Mistral | ~50-100M | Codestral | 2 rpm |
| Google AI Studio | ~30M | Gemma 4 31B IT | 15 rpm, 1000 rpd |
| Zhipu AI | ~30M | GLM-4.7 Flash | — |
| Ollama Cloud | ~20-30M | Gemma 4 31B (Ollama) | — |
| Cloudflare Workers AI | ~18-45M | GPT-OSS 120B (CF) | — |
| Groq | ~15M | ALLaM 2 7B (Groq) | 30 rpm, 1000 rpd |
| xKiro | free · 500K tokens/day (1M with Telegram) | Mistral Large 3 (xKiro) | — |
| OpenRouter | ~6M | North Mini Code (free) | 20 rpm, 50 rpd |
| LLM7 | ~2M (60-100/hr) | Codestral (LLM7) | 40 rpm |
Counting only the pools published in tokens, these free tiers come to over 400 million tokens a month. Add the providers whose free tiers are request-limited rather than token-limited, and the tracked total is about 7.4 billion a month across 600+ models across 34 providers. The model catalog lists every one with its limits.
How failover makes many limits feel like none
FreeLLMAPI is an open-source router you run yourself. You add each provider's free key once, and it serves one OpenAI-compatible endpoint. When a provider answers with a rate limit, the router sends the request to the next provider with quota left. The same open models (Llama, Qwen, GPT-OSS, DeepSeek, Gemma) are served free by several providers each, so a limit on one rarely stops you.
from openai import OpenAI
# FreeLLMAPI runs locally; grab your unified key + endpoint on the Keys page.
client = OpenAI(base_url="http://localhost:3001/v1", api_key="freellmapi-...")
resp = client.chat.completions.create(
model="gpt-oss-120b",
messages=[{"role": "user", "content": "Hello!"}],
)
print(resp.choices[0].message.content)
When every provider is exhausted, requests fail until the earliest quota resets. That is the honest ceiling, and it is far higher than any single free tier.
Keep it working
- Use your own free account on each provider and follow its terms. Shared or resold keys get revoked.
- Keep the router private. It is built for personal use, not as a public proxy.
- Add more providers' free keys for more headroom. Getting a key takes minutes, with no credit card.
Frequently asked questions
Is there a free AI API with unlimited tokens?
No. Every genuine free tier is capped by requests per minute, requests per day or a token pool, and offers of "unlimited" free tokens are trials, shared keys that get revoked, or resold accounts that break the provider's terms. What you can do is combine many free tiers so their limits add up.
How many free AI tokens can I get per month?
The free tiers FreeLLMAPI tracks add up to about 7.4 billion tokens a month across 34 providers. Counting only the pools providers publish in tokens, the free catalog alone is over 400 million a month; the rest are request-limited tiers.
Is there a free LLM API with no rate limit?
No real one. Rate limits are how providers keep free tiers free. FreeLLMAPI tracks each provider's quota and moves to the next one when a request is rate-limited, so you rarely see the limit, but it is still there.
What happens when every free tier is used up?
Requests fail with a rate-limit error until the earliest quota resets, usually within minutes for per-minute limits and the next day for daily ones. Adding more providers' free keys raises the ceiling.
Do I need a credit card for these free tokens?
No. Every provider in the catalog has a free tier that works without a card.
