What's free
Free plan ($0): access to all text LLMs (Gemma, Qwen, etc.), capped at ~5 requests per 2-day window, 12K context, 1 request at a time
Rate limits
1 request at a time; ~5 requests per 2 days across all models; max 12K context; delayed responses
The catch
Free tier is for testing only — very restrictive. Provider advertises zero-log / no data retention. Card requirement for the free tier is not stated on the pricing page.
Quickstart — chat completions
from openai import OpenAI
client = OpenAI(base_url="https://api.arliai.com/v1", api_key="<YOUR_FREE_API_KEY>")
resp = client.chat.completions.create(
model="<a-free-model>",
messages=[{"role": "user", "content": "Hello!"}],
)
print(resp.choices[0].message.content)…or with curl:
curl https://api.arliai.com/v1/chat/completions \
-H "Authorization: Bearer $API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"<a-free-model>","messages":[{"role":"user","content":"Hello!"}]}'
