What Are These Services?
both NanoGPT and OpenRouter do the same thing: give you one API key that accesses multiple AI models from different providers. instead of signing up for OpenAI, Anthropic, Google, and Mistral separately, you use one account.
OpenRouter
- launched in 2023
- 300+ models from 30+ providers
- pay-per-use with credits
- requires email signup
- credit card or crypto payments
- API follows OpenAI format
NanoGPT
- launched in 2024
- 400+ models from 20+ providers
- pay-per-use with credits
- minimal signup (email optional for crypto)
- crypto-first payments (also accepts card)
- API follows OpenAI format
both services route your requests to the underlying model providers (OpenAI, Anthropic, etc.) and charge you a small markup on top of the provider's base rate.
Pricing Comparison
this is what most people care about. i tracked costs on both platforms for 30 days with identical workloads.
Per-Token Pricing (Approximate, per 1M Tokens)
| Model | NanoGPT Input | OpenRouter Input | NanoGPT Output | OpenRouter Output |
|---|---|---|---|---|
| GPT-4o | $2.50 | $2.50 | $10.00 | $10.00 |
| Claude 3.5 Sonnet | $3.00 | $3.00 | $15.00 | $15.00 |
| GPT-4o-mini | $0.15 | $0.15 | $0.60 | $0.60 |
| Gemini 1.5 Pro | $1.25 | $1.25 | $5.00 | $5.00 |
| Mistral Large | $2.00 | $2.00 | $6.00 | $6.00 |
the base rates are almost identical. both services pass through the provider's pricing with a small margin. where they differ is in the markup and minimum charges.
Monthly Cost Test (5M Tokens, Mixed Models)
| Platform | Total Cost | Notes |
|---|---|---|
| NanoGPT | $7.20 | Crypto deposit, no fees |
| OpenRouter | $8.50 | Credit card deposit, 3% processing fee |
the difference comes from payment processing. NanoGPT's crypto deposits have zero fees. OpenRouter charges a processing fee on credit card deposits.

Model Availability
OpenRouter Models (300+)
OpenRouter has a larger raw model count. they add new models quickly — sometimes within days of release. notable additions:
- all OpenAI models (GPT-4o, GPT-4, GPT-3.5)
- all Anthropic models (Claude 3.5, Claude 3)
- Google models (Gemini Pro, Gemini Flash)
- Meta models (Llama 3, Llama 2)
- Mistral models
- open-source models (many via Together.ai, Fireworks)
- some exclusive/perplexity models
NanoGPT Models (400+)
NanoGPT has more total models but some are variations of the same base. notable:
- all major models (GPT-4o, Claude, Gemini, Mistral, Llama)
- many fine-tuned variants
- some models not on OpenRouter (check their model list)
- simpler model naming (no provider prefixes)
Model Comparison Table
| Category | NanoGPT | OpenRouter | Winner |
|---|---|---|---|
| Total models | 400+ | 300+ | NanoGPT |
| Major providers | All | All | Tie |
| Open-source models | Many | More | OpenRouter |
| Model updates speed | Fast | Faster | OpenRouter |
| Model naming | Simple | Complex | NanoGPT |
in practice, both have every model you'd actually want to use. the 100+ model difference is mostly fine-tuned variants and minor versions.

Privacy and Security
this is where the services diverge significantly.
OpenRouter Privacy
- requires email signup
- tracks usage per model
- logs requests for rate limiting
- credit card payments linked to identity
- US-based company
- standard privacy policy
NanoGPT Privacy
- email optional (can use crypto-only)
- minimal usage tracking
- crypto payments (Monero, Bitcoin, Nano)
- no identity verification for crypto deposits
- privacy-first design
- less data retention
Privacy Comparison
| Feature | NanoGPT | OpenRouter |
|---|---|---|
| Email required | Optional | Yes |
| Crypto payments | Yes (Monero, BTC, Nano) | Yes (limited) |
| Anonymous usage | Possible | No |
| Request logging | Minimal | Standard |
| Identity verification | None for crypto | KYC for large amounts |
| Data retention | Unclear (minimal stated) | Standard (30 days) |
if privacy is your priority, NanoGPT wins. you can fund an account with Monero and use it without providing any personal information. OpenRouter requires at least an email address.

API Compatibility
both services use the OpenAI-compatible API format. this means any tool that works with OpenAI's API works with either service.
API Comparison
| Feature | NanoGPT | OpenRouter |
|---|---|---|
| Base URL format | api.nano-gpt.com/v1 | openrouter.ai/api/v1 |
| OpenAI compatible | Yes | Yes |
| Streaming support | Yes | Yes |
| Function calling | Yes | Yes |
| Vision support | Yes | Yes |
| Rate limits | Generous | Varies by model |
| API key format | Bearer token | Bearer token |
Tool Compatibility
both work with:
- Open WebUI
- LibreChat
- SillyTavern
- Cursor IDE
- Continue.dev
- Aider
- Any OpenAI-compatible client
setup is nearly identical. you change the base URL and API key. our Open WebUI setup guide and LibreChat setup guide walk through the process for NanoGPT.
User Experience
Web Interface
OpenRouter has a more polished web interface. model browsing is better organized, usage stats are clearer, and the dashboard feels more professional.
NanoGPT's interface is simpler. it works, but it's not going to win design awards. for most users, this doesn't matter — you'll spend 95% of your time in whatever client you connect to the API.
Documentation
OpenRouter has better documentation. more examples, clearer explanations, better-organized API docs.
NanoGPT's documentation is minimal. you basically get a list of models, an API endpoint, and that's it. if you've used OpenAI's API before, you'll figure it out. if you're new to APIs, OpenRouter is easier to start with.
Support
both have limited support. OpenRouter has a Discord community. NanoGPT has email support. neither has phone support or live chat.
When to Choose NanoGPT
pick NanoGPT if:
- privacy matters — crypto payments, minimal tracking
- you want simplicity — fewer decisions, straightforward pricing
- you use SillyTavern — the community has better NanoGPT guides
- you prefer crypto payments — Monero, Bitcoin, Nano accepted
- you don't need fancy docs — you already know how APIs work
When to Choose OpenRouter
pick OpenRouter if:
- you want the largest model catalog — 300+ models, fast updates
- you need good documentation — especially if you're new to APIs
- you want a polished UI — better dashboard and usage stats
- you're in the US — lower latency to US-based providers
- you want community support — active Discord server

My Verdict
i use both. seriously.
OpenRouter for testing new models (they add them faster). NanoGPT for daily use (better privacy, crypto payments, simpler).
if i had to pick one: NanoGPT. the privacy advantage matters to me, and the model catalog is close enough.
if privacy doesn't matter to you and you want the shiniest new models on day one: OpenRouter.
