NanoGPT vs OpenRouter: Pricing, Models, and Privacy
two multi-model AI aggregators. one account, dozens of providers. i've been running both side by side for 3 months to figure out which one actually delivers.
TL;DR: pricing is nearly identical. NanoGPT wins on privacy and crypto payments. OpenRouter wins on model catalog size and developer tooling. pick based on what matters more to you.

What Are These Services?
NanoGPT and OpenRouter are API aggregators. you sign up once, get one API key, and access models from OpenAI, Anthropic, Google, Mistral, Meta, and dozens of smaller providers.
instead of managing 5 separate API accounts, you manage 1.
the difference: they're built by different teams with different priorities. OpenRouter focuses on developer experience and model variety. NanoGPT focuses on privacy and simplicity.
Pricing Comparison
i ran identical workloads on both platforms for 30 days. here's what i found.
Per-Token Rates (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 |
| Llama 3 70B | $0.90 | $0.90 | $0.90 | $0.90 |
base rates are almost identical. both pass through provider pricing with a small margin. the real cost difference comes from payment processing and minimum deposits.
30-Day Cost Test (Mixed Usage, ~5M Tokens)
| Platform | Total Cost | Payment Method | Processing Fee |
|---|---|---|---|
| NanoGPT | $7.20 | Crypto (Monero) | $0.00 |
| OpenRouter | $8.50 | Credit card | ~3% |
NanoGPT's crypto deposits have zero fees. OpenRouter charges processing on credit card deposits. over a year that 3% adds up — you'd save roughly $4-5 on NanoGPT with crypto payments.

Model Availability
OpenRouter (300+ Models)
OpenRouter adds new models fast. sometimes within 24 hours of a provider releasing something new. their catalog includes:
- 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 via Together.ai, Fireworks
- some exclusive/perplexity models
NanoGPT (400+ Models)
NanoGPT has more total models, though some are fine-tuned variants of the same base:
- all major models (GPT-4o, Claude, Gemini, Mistral, Llama)
- many fine-tuned variants
- some models not on OpenRouter
- simpler model naming (no provider prefixes)
Model Comparison
| Category | NanoGPT | OpenRouter | Winner |
|---|---|---|---|
| Total models | 400+ | 300+ | NanoGPT |
| Major providers | All | All | Tie |
| Open-source models | Many | More | OpenRouter |
| Update speed | Fast | Faster | OpenRouter |
| Model naming | Simple | Complex | NanoGPT |
in practice, both have every model you'd actually use daily. the 100+ difference is mostly variants.
Model Update Speed
when a new model drops (like a new Claude or GPT version), how fast do these platforms add it?
| Scenario | NanoGPT | OpenRouter |
|---|---|---|
| Major model release | 1-3 days | 1-2 days |
| Open-source model | 3-7 days | 1-3 days |
| Model deprecation | Fast | Fast |
OpenRouter is slightly faster at adding new models. NanoGPT is close behind. for most users the difference is irrelevant — both have the models you want within a week of release.

Privacy and Security
this is where the two platforms diverge hard.
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 (crypto-only account possible)
- minimal usage tracking
- crypto payments (Monero, Bitcoin, Nano)
- no identity verification for crypto deposits
- privacy-first design
- less data retention
Privacy Head-to-Head
| Feature | NanoGPT | OpenRouter |
|---|---|---|
| Email required | Optional | Yes |
| Crypto payments | Yes (Monero, BTC, Nano) | Yes (limited) |
| Anonymous usage | Possible | No |
| Request logging | Minimal | Standard |
| ID verification | None for crypto | KYC for large amounts |
| Data retention | Minimal stated | 30 days |
if you care about privacy, NanoGPT wins. fund an account with Monero, never give personal info. OpenRouter at minimum wants an email address.

Frequently Asked Questions
Is NanoGPT cheaper than OpenRouter?
base rates are nearly identical. the real savings come from NanoGPT's zero-fee crypto deposits vs OpenRouter's ~3% credit card processing. over a year you save $4-5 on NanoGPT.
Can I use both services at the same time?
yes. both use the OpenAI-compatible API format. you can configure different tools to use different services — e.g. NanoGPT for SillyTavern, OpenRouter for your coding IDE.
Which has better privacy?
NanoGPT. you can create an account with just crypto, no email needed. OpenRouter requires email and has standard US-based data retention policies.
Do both support streaming?
yes. both support server-sent events streaming just like the OpenAI API.
Which service is more reliable?
both have solid uptime in my experience. OpenRouter has been around longer (since 2023) and has more battle-tested infrastructure. NanoGPT (since 2024) has been reliable in my 3 months of testing.
My Verdict
after running both for 3 months, i keep NanoGPT as my primary. the privacy angle matters to me — i don't want my AI usage tied to my credit card. and the pricing difference with crypto is real.
OpenRouter is the better choice if you're a developer who needs detailed analytics and the absolute widest model selection. for everyone else, NanoGPT does the job.
