NanoGPT vs OpenRouter: Real Pricing, Real Models, Real Talk
look, i'll save you 2000 words: NanoGPT wins on privacy, OpenRouter wins on model count. everything else is close enough that it doesn't matter as much as you think.
i ran both side by side for 3 months. same prompts, same models, tracked every cent. here's what actually happened.
tl;dr: NanoGPT wins for privacy-focused users. zero-fee crypto deposits, anonymous accounts, and every major model you actually use. OpenRouter wins if you need maximum model diversity and detailed analytics. for most people, NanoGPT is the better pick.
key takeaways:
- pricing is nearly identical, but NanoGPT's zero-fee crypto deposits save money over time
- NanoGPT lets you pay with Monero for truly anonymous usage, OpenRouter requires credit card
- every major model (GPT-4o, Claude, Gemini) is on both platforms, so model count differences rarely matter
the 30-second version
i use NanoGPT daily. i still have an OpenRouter account. i don't regret either choice, but i reach for NanoGPT 9 times out of 10. why? because my API calls aren't tied to my credit card, and the models i actually use (GPT-4o, Claude, Gemini) are on both platforms anyway.
if you're a developer who needs every obscure open-source model the day it drops, OpenRouter is your tool. if you want privacy and simplicity, NanoGPT is it.
pricing: where the real money goes
base token rates are almost identical. both pass through provider pricing with a small markup. you won't save a meaningful amount by switching platforms alone.
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 |
same models, same prices. the difference isn't in the rates - it's in how you pay.
what actually costs more: deposits
| Platform | Payment Method | Processing Fee | Minimum Deposit |
|---|---|---|---|
| NanoGPT | Crypto (Monero) | $0 | $8 |
| NanoGPT | Credit card | ~3% | $8 |
| OpenRouter | Credit card | ~3% | $5 |
| OpenRouter | Crypto | Varies | $5 |
NanoGPT's zero-fee crypto deposits are the real differentiator. i've deposited with Monero probably 20 times now and never paid a cent in fees. on OpenRouter, my credit card deposits always had the ~3% hit.
over 3 months with about $25 total spend, i saved roughly $0.75 on processing fees alone. that's not life-changing. but over a year at $100+ spend, it adds up to $3-4. and more importantly, my crypto deposits don't show up on a credit card statement.
check the NanoGPT pricing guide for a full cost breakdown by model.
my actual 30-day cost test
| Platform | Tokens Used | Total Cost | Payment Method |
|---|---|---|---|
| NanoGPT | ~5M | $7.20 | Crypto (Monero) |
| OpenRouter | ~5M | $8.50 | Credit card |
the $1.30 difference was almost entirely processing fees and rounding. the base cost was nearly identical. don't pick your platform based on pricing alone.
models: who has more, and does it matter?
the numbers
OpenRouter claims 300+ models. NanoGPT claims 400+. both numbers are a bit inflated by counting fine-tuned variants and minor versions separately.
here's what matters: every model i actually use is on both platforms.
GPT-4o? both. Claude 3.5? both. Gemini Pro? both. Mistral Large? both. Llama 3 70B? both. GPT-4o-mini? both.
the 100-model difference is mostly stuff like llama-3-70b-instruct-q4_K_M vs llama-3-70b-instruct-q5_K_M - quantized variants of the same model that 95% of users will never touch.
where OpenRouter wins
OpenRouter adds new models faster. when a new Claude or GPT version drops, it's usually on OpenRouter within 1-2 days. NanoGPT takes 1-3 days. not a huge gap, but if you're the type who needs to test a new model the hour it releases, OpenRouter is your friend.
OpenRouter also has more open-source models from providers like Together.ai and Fireworks. if you're running specialized workloads on obscure models, OpenRouter has the edge.
where NanoGPT wins
NanoGPT's model naming is simpler. no provider prefixes, no confusing versions. you pick "GPT-4o" and get GPT-4o. OpenRouter sometimes has multiple entries for the same model from different providers, which can be confusing.
NanoGPT also has some models that OpenRouter doesn't carry, though these tend to be niche fine-tunes.
model count 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, for daily use, this is a tie. both have what you need.
privacy: the real reason i use NanoGPT
this is where the two platforms are genuinely different. not slightly different. fundamentally different.
OpenRouter's approach
- email required for signup
- usage tracked per model
- request logs for rate limiting
- credit card payments tied to identity
- US-based company, standard privacy policy
- data retention: 30 days minimum
NanoGPT's approach
- email optional - you can run crypto-only
- minimal usage tracking
- crypto payments (Monero, Bitcoin, Nano) with no identity link
- no KYC for crypto deposits
- privacy-first design philosophy
- less data retention
what this actually means
with OpenRouter, every API call you make is linked to your email and potentially your credit card. that's standard for most services. nothing unusual.
with NanoGPT, i funded my account with Monero. no email. no name. no credit card. my API usage is just... usage. not tied to me.
if you're doing anything where privacy matters - journalism, research, sensitive business queries, or you just don't want a tech company building a profile on your AI usage - this is a real difference. not a marketing bullet point. a real architectural difference.
i wrote a deeper dive on this in the NanoGPT privacy review. and if you want to pay with crypto, here's my AI with crypto payment guide.
the downside of NanoGPT's privacy
less infrastructure around account recovery. if you lose access to a crypto-only account, you're starting over. OpenRouter's email-based accounts are easier to recover. there's a trade-off between privacy and convenience, and NanoGPT leans hard toward privacy.
API compatibility: they're basically the same
both use OpenAI-compatible API format. this means any tool built for OpenAI's API works with either service with just a URL change.
what works with both
- Open WebUI
- LibreChat
- SillyTavern
- Cursor IDE
- Continue.dev
- Aider
- any OpenAI-compatible client
API comparison
| Feature | NanoGPT | OpenRouter |
|---|---|---|
| Base URL | api.nano-gpt.com/v1 | openrouter.ai/api/v1 |
| OpenAI compatible | Yes | Yes |
| Streaming | Yes | Yes |
| Function calling | Yes | Yes |
| Vision support | Yes | Yes |
| Rate limits | Generous | Varies by model |
for developers, switching between the two is a one-line URL change. if you want to set up NanoGPT with Open WebUI, here's my setup guide. for Python API usage, check the API tutorial.
user experience: the honest version
NanoGPT's UI
it's clean and minimal. no clutter, no ads. the model selector does its job. conversation history works. it's not going to win design awards, but i don't need it to. i need it to let me pick a model and send a prompt. it does that.
mobile works fine in a browser, but there's no native app.
OpenRouter's UI
more feature-rich. model comparison tools, usage analytics dashboard, a playground for testing models. it feels more like a developer tool than a consumer product.
if you want to benchmark models against each other or analyze your token usage across providers, OpenRouter has better tooling for that.
my take
NanoGPT's UI is better for daily use. OpenRouter's UI is better for exploration and analysis. i spend 95% of my time just sending prompts, so NanoGPT's simplicity wins for me.
reliability
both are solid. no meaningful difference in uptime or latency.
both have been solid in my 3 months of testing. neither has had a major outage that affected me.
| Metric | NanoGPT | OpenRouter |
|---|---|---|
| Uptime (my test) | ~99.5% | ~99.5% |
| Average latency | Fast | Fast |
| Peak hour slowdowns | Rare | Occasional |
OpenRouter has been around since 2023 - more battle-tested infrastructure. NanoGPT launched in 2024 but has been reliable for me. i haven't had a single failed API call on either platform that wasn't my own fault.
who should use which
nanoGPT for privacy. openRouter for model diversity.
use NanoGPT if you:
- value privacy and want anonymous usage
- pay with crypto (especially Monero)
- want zero processing fees on deposits
- prefer simple interfaces
- use a small number of core models (GPT-4o, Claude, Gemini, Mistral)
use OpenRouter if you:
- need every open-source model the day it drops
- want detailed usage analytics and model comparison tools
- prefer credit card payments
- are building production apps that need model diversity
- want a playground to test different models side by side
use both if you:
- are a developer who wants redundancy
- want to test across the widest possible model selection
- care about privacy for some use cases and model variety for others
that's what i do. NanoGPT is my daily driver. OpenRouter is my backup for the occasional niche model.
the verdict
after 3 months, i kept NanoGPT as my primary. the privacy angle matters to me - i don't want my AI usage on a credit card statement. the pricing is effectively the same. and every model i actually use daily is on both platforms.
OpenRouter is the better choice if you're a developer who needs maximum model diversity and detailed analytics. for everyone else - especially if you care about privacy - NanoGPT is the better pick.
