Which one is for you
Pick NanoGPT if
- Fits if you ask an AI something now and then and would rather pay per message
- Works for developers who want one API key for lots of model providers
Look elsewhere if
- Skip it if you want an app on your phone or desktop, as it's a website and an API
- Not for you if you want one flat bill, since Pro still charges per use for models like Claude Opus 5.5
- Tight if you're staying free, because that's a single model on the web
- Watch out: pinning a provider by hand adds 5%, and your own key is billed at 5% of the model's cost
- Too light for chatting with your own documents, which isn't listed, and it names no integrations
Pick OpenRouter Chat if
- Fits if you want to see how several models answer the same prompt
- Works for developers who want one API in front of many providers
Look elsewhere if
- Skip it if you want an assistant with memory and file tools, as the chat page has neither
- Tight if you stay free, with 50 requests a day on free models only
- Watch out: a 5.5% fee on credit purchases on Standard, and 8% on Business
- Watch out: a negative credit balance blocks the free models until you add credits
How we grade them
| 2.2GPANanoGPTFair | 2.0GPAOpenRouter ChatFair | |
|---|---|---|
| Value for money | CPro is $12 a month, which is exactly this category's middle figure, and even on it models like Claude Opus 5.5 are still billed per use. You needn't subscribe at all: put $1 on a balance and pay each model's list price with no markup. Pinning a provider by hand adds 5%, mind, as does using your own key. | CThere is no subscription: you buy credits at each provider's list price plus a 5.5% fee on Standard. That does not map onto the $12 monthly category middle, so it sits mid-pack. |
| Free plan and trial | COne free model, on the web, and that's the lot. Everything else comes out of a prepaid balance, so you reach the end of the free part on day one. | C25+ free models for chat and API, limited to 50 requests a day and 20 a minute. A negative credit balance blocks them until you add credits. |
| Features | BThe directory lists 641 text models, 224 image, 183 video, 98 audio and 13 3D, with an API in OpenAI's and Anthropic's formats covering images, video, audio, embeddings and web search. It's a browser tab and an API, though, with nothing listed for chatting with your own documents. | CSide-by-side comparison, routing and fallback, spend controls and one API across 600+ models. The chat page has no memory or file tools, so it is a playground, not a full assistant. |
| Ease of use | CNo rating on record. You can type in an anonymous session with no account, but paying by the token and keeping a balance topped up is a way of thinking you have to pick up first. | CNo store rating on record. You pick models, buy credits and manage keys, which is a small learning curve for a chat window. |
| Platforms and integrations | CA website and an API, and that's it. The pricing page mentions no desktop or phone app, and the listing names no integrations. | CWeb only, with an API that works through the OpenAI SDK. No desktop or phone app is listed. |
| Best for | paying per message instead of per month | comparing many AI models side by side |

Key features
NanoGPT
- Hundreds of models in one place
- The model directory lists 641 text, 224 image, 183 video, 98 audio and 13 3D models, including ChatGPT, Claude and Gemini, all used from one chat interface and one balance.
- Per-use billing at list prices
- Text models are billed at the provider's list price per million tokens with no markup, and deposits carry no percentage fee. Each API response reports the exact cost charged.
- OpenAI-compatible API
- The API follows OpenAI's chat completions and Responses formats and Anthropic's Messages format, and also covers images, video, audio, embeddings, web search and batch jobs.
- No stored prompts by default
- Prompt and conversation content is not kept on NanoGPT's servers unless you turn on sync or sharing, and the service can be used in an anonymous session with no account.
- Card and crypto payments
- A balance can be started from $1 by card or $0.10 in cryptocurrency. Selected API endpoints also accept accountless crypto payments with no API key.
- TEE-backed models
- Some models run in trusted execution environments, and the API returns attestation reports and request signatures so that this can be verified.
OpenRouter Chat
- Side-by-side comparison
- Pick several models, send one message to each and read the answers next to each other in the chat playground.
- 600+ models
- The paid plans reach 600+ models from OpenAI, Google, Anthropic and other providers; the Free plan covers 25+ free models.
- One API
- The API is OpenAI-compatible, so changing the base URL and model names is the migration step OpenRouter describes.

- Spend controls
- Standard and above add budgets and spend controls, plus prompt caching and a management API key.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
