What Exactly Is NanoGPT?
NanoGPT sits between you and the big AI providers. instead of signing up separately for OpenAI, Anthropic, Google, and Mistral — each with their own billing, their own API keys, their own terms — you sign up once at NanoGPT and get a single API key that routes to all of them.
the concept is simple. you top up credits. you pick a model. you send a request. NanoGPT forwards it to the right provider and charges you the actual token cost (usually cheaper than going direct).
here's what makes it different from ChatGPT Plus or Claude Pro:
| Feature | NanoGPT | ChatGPT Plus | Claude Pro | OpenRouter |
|---|---|---|---|---|
| Monthly Cost | From $8 | $20 | $20 | Pay-per-use |
| Number of Models | 50+ | 3-4 | 2-3 | 100+ |
| API Access | Yes | No | Yes | Yes |
| Contract | None | Monthly | Monthly | None |
| Crypto Payment | Yes | No | No | Yes |
| Privacy Focus | Strong | Weak | Medium | Medium |
the comparison to OpenRouter is worth noting. OpenRouter is similar in concept but NanoGPT tends to be cheaper on the models most people actually use (GPT-4o, Claude 3.5). we have a detailed NanoGPT vs OpenRouter comparison if you want the full breakdown.
Setting Up NanoGPT (5-Minute Walkthrough)
i've set up NanoGPT on multiple devices now. here's the exact process:
Step 1: Create Your Account
go to nano-gpt.com and sign up. email + password, that's it. no phone number, no ID verification. takes about 30 seconds.
Step 2: Top Up Credits
NanoGPT uses a credit system. minimum top-up is $8. you can pay with:
- Crypto (BTC, ETH, LTC, and others) — best for privacy
- Credit card — fastest option
- Other methods vary by region
if you want to pay with crypto anonymously, check our guide on how to buy crypto without KYC.
Step 3: Generate Your API Key
Settings → API Keys → Create New Key. copy it somewhere safe. this key is your universal ticket to every model NanoGPT supports.
Step 4: Start Using It
two options:
option a: web interface. NanoGPT has a built-in chat interface. pick a model, start typing. this is the easiest way to get started.
option b: API integration. plug your key into any OpenAI-compatible tool. works with Open WebUI, LibreChat, SillyTavern, and basically anything that accepts an OpenAI API endpoint.
# basic API call with curl
curl https://api.nano-gpt.com/v1/chat/completions \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "gpt-4o",
"messages": [{"role": "user", "content": "Hello!"}]
}'
for detailed API setup, see our NanoGPT API key setup guide. if you're using SillyTavern specifically, we have both a standard setup guide and a private API guide.
Which Models Should You Use?
this is where NanoGPT shines. after testing dozens of models over 2 months, here's my honest ranking by use case:
For Writing and Editing
| Model | Quality | Speed | Cost | My Rating |
|---|---|---|---|---|
| Claude 3.5 Sonnet | Excellent | Fast | Medium | ⭐⭐⭐⭐⭐ |
| GPT-4o | Very Good | Fast | Medium | ⭐⭐⭐⭐ |
| Claude 3 Haiku | Good | Very Fast | Low | ⭐⭐⭐ |
| Mistral Large | Good | Fast | Low | ⭐⭐⭐⭐ |
my pick: Claude 3.5 Sonnet. hands down. it structures long-form content better than anything else i've tested. if cost is a concern, Mistral Large is surprisingly good at about half the price.
For Coding
| Model | Quality | Speed | Cost | My Rating |
|---|---|---|---|---|
| GPT-4o | Excellent | Fast | Medium | ⭐⭐⭐⭐⭐ |
| Claude 3.5 Sonnet | Very Good | Fast | Medium | ⭐⭐⭐⭐ |
| Mistral Large | Good | Fast | Low | ⭐⭐⭐⭐ |
| GPT-4o-mini | Decent | Very Fast | Very Low | ⭐⭐⭐ |
my pick: GPT-4o for complex code. GPT-4o-mini for quick scripts and simple debugging — it's dirt cheap and fast enough.
For Research and Analysis
| Model | Quality | Speed | Cost | My Rating |
|---|---|---|---|---|
| Gemini 1.5 Pro | Excellent | Medium | Medium | ⭐⭐⭐⭐⭐ |
| Claude 3.5 Sonnet | Very Good | Fast | Medium | ⭐⭐⭐⭐ |
| GPT-4o | Good | Fast | Medium | ⭐⭐⭐⭐ |
my pick: Gemini 1.5 Pro when you're working with long documents. its context window is massive — up to 1 million tokens. for shorter research tasks, Claude 3.5 is fine.
For Budget Usage
if you're watching every cent, use these models:
- GPT-4o-mini — cheapest OpenAI model, good enough for 80% of tasks
- Claude 3 Haiku — Anthropic's budget option, fast
- Mistral Small — open source, very cheap
check our complete model comparison for the full list with pricing.
NanoGPT Pricing: What You Actually Pay
let's talk real numbers. i tracked my spending for 2 months:
Month 1 (Testing Phase)
- heavy usage, switching between models constantly
- roughly 3 million tokens consumed
- total cost: $11.47
Month 2 (Regular Usage)
- daily work use: writing, code, research
- roughly 2 million tokens consumed
- total cost: $7.82
Cost Comparison by Usage Level
| Usage | NanoGPT | ChatGPT Plus | Claude Pro | OpenAI API |
|---|---|---|---|---|
| Light (500K tokens) | ~$2-3 | $20 | $20 | ~$5 |
| Medium (2M tokens) | ~$5-8 | $20 | $20 | ~$10-15 |
| Heavy (5M tokens) | ~$12-18 | $20 | $20 | ~$25-35 |
| Very Heavy (10M+) | ~$25-40 | $20 | $20 | ~$50-70 |
the math is clear. if you use AI lightly, NanoGPT saves you 80%+. if you use it heavily, you still save 30-50% compared to going direct. the only scenario where ChatGPT Plus wins is if you exclusively use GPT-4 and send thousands of messages a month.

Connecting NanoGPT to Your Favorite Tools
NanoGPT's biggest strength is compatibility. because it uses the OpenAI API format, it works with almost everything:
Open WebUI
free, open-source chat interface. drop in your NanoGPT API key and you get a ChatGPT-like experience with any model. our Open WebUI setup guide walks through it.
LibreChat
another open-source option with more features: conversation branching, file uploads, multi-user support. LibreChat setup guide.
SillyTavern
popular for roleplay and creative writing. NanoGPT works great here because you can switch models mid-conversation. SillyTavern setup | Private API setup.
Python / Node.js / Any Language
the API is standard OpenAI format. use the official OpenAI SDK with a custom base URL:
from openai import OpenAI
client = OpenAI(
api_key="your-nanogpt-key",
base_url="https://api.nano-gpt.com/v1"
)
response = client.chat.completions.create(
model="claude-3.5-sonnet",
messages=[{"role": "user", "content": "Hello!"}]
)
print(response.choices[0].message.content)
check our Python API tutorial for more examples.
NanoGPT for Developers
if you're building something, NanoGPT is genuinely useful:
- model fallback: try GPT-4o first, fall back to Claude if it fails
- cost optimization: use cheap models for simple tasks, expensive ones for complex ones
- A/B testing: same prompt, different models, compare outputs
- no vendor lock-in: swap providers without changing your code
NanoGPT handles rate limits and routing internally. you don't need to manage multiple API keys or worry about individual provider quotas. our developer guide covers advanced patterns.
Privacy: How NanoGPT Handles Your Data
this matters. here's what i found after digging into their docs and asking support:
- conversations are not used for training. unlike ChatGPT free tier.
- API requests are proxied, not stored long-term. metadata (model, token count) is logged for billing.
- no account linking. you don't need a Google or Microsoft account.
- crypto payments. you can stay semi-anonymous if you pay with crypto.
it's not perfect privacy — NanoGPT still sees your prompts in transit. but compared to ChatGPT (owned by a company that explicitly trains on your data), it's a significant upgrade. read our full privacy review for the details.
if you want maximum privacy, pair NanoGPT with a VPN and pay with crypto from a no-KYC exchange. for the complete privacy picture, check our AI privacy guide.
NanoGPT vs the Competition
quick head-to-head:
| NanoGPT | ChatGPT Plus | Claude Pro | OpenRouter | |
|---|---|---|---|---|

Frequently Asked Questions
Is NanoGPT legit?
yes. i've been using it for 2 months with my own money. it works exactly as advertised. the API is reliable, models respond correctly, and billing is transparent.
Can I use NanoGPT for free?
no free tier. minimum top-up is $8. but at $2-3/month for light usage, that $8 lasts a while.
Does NanoGPT work on mobile?
it works in mobile browsers. there's no dedicated iOS or Android app. the web interface is responsive though.
What happens if NanoGPT goes down?
your API calls fail, same as any API. your credits stay in your account. in 2 months i've had maybe 2 brief outages (under 10 minutes each).
Is NanoGPT faster than ChatGPT?
in my experience, yes. there's no queuing system like ChatGPT has during peak hours. response times depend on the underlying model, but the proxy itself adds minimal latency.
Can I get a refund on unused credits?
check their current policy. as of my last check, credits don't expire but refunds aren't standard.
My Final Verdict
NanoGPT isn't perfect. the UI is basic. there's no mobile app. you need to know which model to use for which task.
but the value proposition is undeniable. access to 50+ AI models for $8/month instead of being locked into one provider for $20. if you use AI daily and care about flexibility — or privacy — it's the best option available right now.
i've fully switched. ChatGPT Plus cancelled. Claude Pro cancelled. one NanoGPT account, done.
