Effectively unlimited for everyday use
Fast streaming output and custom request-aware routing support long working sessions. Ordinary users spend more time reading, deciding, and iterating than continuously generating.
Free AI · No signup · No API key · No billing
Free AI for chat, apps, and agents

A free AI API without a key or a bill
Vireonix removes the usual signup, credit-card, and API-key steps while keeping the request format familiar.
Drop-in OpenAI compatibility
Point an OpenAI-style chat-completions client at Vireonix, remove the authorization header, and start sending requests.
No hidden “free trial”
There is no trial balance to expire, no card to add, and no per-token invoice for ordinary access under the fair-use policy.
Limits you can verify
Read remaining hourly capacity from the limits endpoint and response headers so your application can back off cleanly.
One choice. The right model for every task.
Use Auto once and let Vireonix choose from its model pool on every request.

Free AI API questions
Is the Vireonix AI API really free?
Yes. Ordinary use requires no payment method, account, or API key. Per-IP hourly budgets and the acceptable-use terms still apply.
Is Vireonix an unlimited AI API?
Not literally. It can feel effectively unlimited during ordinary interactive use because responses stream at usable model speeds and human reading and iteration time makes continuous quota saturation unusual. Sustained concurrent automation can still reach the hourly limits.
Can I use an OpenAI SDK with Vireonix?
Vireonix exposes an OpenAI-compatible chat-completions endpoint. Set the base URL to vireonix.ai and do not send an authorization header.
Can I resell Vireonix AI inference tokens?
Yes. You may sell customer-facing credits or metered AI inference access powered by Vireonix under the reseller terms. Hourly limits, acceptable-use rules, and privacy disclosure requirements still apply.
