Vynaris vs NanoGPT
Both take Monero. Only one refunds a bad answer.
Vynaris is the only AI API you can pay for in Monero that refunds bad answers. Pay in XMR for complete payment privacy, let the router pick a right-sized model for each request, and get credit back when an answer misses.
Side by side
Where each one is stronger.
| Vynaris | NanoGPT | |
|---|---|---|
| Refund for a bad answer | Yes. Report a weak model=auto answer within 7 days and get the request refunded as credit. | No answer-quality refunds. A feedback form, but no credit back. source |
| Pay with Monero | Yes. Straight to our own wallet, no payment processor. Any pack at +20%. | Yes, through a BTCPay invoice. source |
| Picks the right model for each request | Every model=auto request starts at frontier quality and routes down only when eval evidence certifies a cheaper model for that task. | auto-model-basic picks a model included in your subscription. Otherwise you choose the model. source |
| Privately hosted uncensored models | Four Vynaris-hosted reduced-refusal models. Prompts and outputs are never stored. | Uncensored models served by third-party providers. source |
| Cost of each request | Receipt in the response headers, plus a CSV ledger. | Exact cost on the response, plus a 24-hour billing lookup by request ID. source |
| Fee on model usage | 3% on your first $500 each month, then 1%. | List price with no markup on auto-routed text models; 5% when you pin a provider. source |
| Catalog size | A curated routing pool plus four hosted uncensored models. | About 1,000 text, image, video, audio and embedding models. source |
| Other crypto | Stablecoins through checkout. | BTC, LTC, DOGE, ZEC, Nano, USDC, USDT and more. source |

Why switch
Pay privately, then stop paying for bad answers.
NanoGPT is a wide catalog at list price. Vynaris is for when you’d rather not pick a model per call: send model=auto and the router starts at frontier quality, drops to a cheaper model only when the evals say it’s safe for that task, and shows the receipt. If an answer still misses, report it and the request is refunded. Need a model that engages with red-team and security work? Call one of the Vynaris-hosted uncensored models directly. Prompts and outputs on those are never stored.
