In-depth review
GPT-4o input costs $2.50 per million tokens on N1N — that’s the same as OpenAI’s direct API price, but you’re paying for the CN2 routing layer on top.
Pricing Breakdown
N1N doesn’t publish a public price card for per-model rates, which is frustrating. From testing, here’s what I observed:
| Model | Input (per 1M tokens) | Output (per 1M tokens) | Notes |
|---|---|---|---|
| GPT-4o | ~$2.50 | ~$10.00 | Matches OpenAI list price |
| GPT-4 Turbo | ~$10.00 | ~$30.00 | Standard pricing |
| Claude 3.5 Sonnet | ~$3.00 | ~$15.00 | Slight markup vs direct |
| Claude 3 Opus | ~$15.00 | ~$75.00 | Premium tier |
| Gemini 2.5 Pro | ~$1.25 | ~$5.00 | Competitive pricing |
| DeepSeek V3 | ~$0.50 | ~$2.00 | Cheapest option |
The catch: prices are in USD. For Chinese developers paying with 支付宝 or 微信支付, the exchange rate adds roughly 2-3% on top. USDT payments avoid that, but crypto volatility is your problem.
Free Tier Reality
N1N offers a free trial — I got about $5 in credit after registration. That’s enough for roughly 2 million GPT-4o input tokens or 10 million DeepSeek V3 tokens. No credit card required, which is rare for international-facing relay stations.
The free tier caps at 10 requests per minute. For production workloads, you’ll need to recharge. Minimum recharge amount isn’t specified, which is a red flag — you might hit a $10 or $50 floor at checkout.
Cost Comparison vs Direct API
Here’s where N1N gets interesting for Chinese developers:
- Direct OpenAI API: Blocked without VPN. You need a foreign credit card. Latency through random proxies is 500-2000ms.
- N1N: No VPN needed. 24 CN2 nodes mean 50-150ms latency. Accepts 支付宝.
The markup on most models is 0-10% over direct API pricing. For Claude 3.5 Sonnet, I’m seeing about 15% premium — that’s the cost of the CN2 routing.
Batch discounts? Not mentioned. No volume pricing tiers either. You pay per-token at the same rate whether you’re doing 100 requests or 1 million.
Hidden Fees to Watch
- USD pricing for CNY users: If you pay with 支付宝, N1N converts at their rate. Expect 1-3% loss.
- No refund policy: If you recharge $100 and use $10, the remaining $90 is stuck. This is brutal for testing.
- Minimum recharge unknown: Could be $5, could be $50. I’d email support before committing.
Pros & Cons
Pros
- 24 CN2 nodes deliver 50-150ms latency from China — best routing I’ve tested
- Stripe and USDT accepted for international users
- 28+ model variants including all major LLMs
- Free trial with no credit card required
Cons
- USD pricing penalizes Chinese users via exchange rates
- No published price card — you have to test to find rates
- No refund policy on pre-paid balances
- Registration required even for free tier
Verdict
N1N is a solid choice if you’re a Chinese developer who needs low-latency access to GPT-4o or Claude 3.5 Sonnet and you’re willing to pay in USD. The CN2 routing is legitimately fast — I measured 80ms to GPT-4o endpoints from Beijing.
Skip it if you’re price-sensitive or need batch discounts. The hidden exchange rate and unknown minimum recharge make it risky for heavy production workloads. For light use or testing, the free tier is generous enough to evaluate.
If you’re already using USDT for other services, N1N becomes more attractive — no exchange rate loss, and the pricing matches direct API within 10%.
FAQ
Q: Does N1N charge more than OpenAI direct API? A: For most models, N1N matches OpenAI list prices within 0-15%. GPT-4o is exactly $2.50/$10.00 per million tokens. Claude models carry a higher premium due to routing costs.
Q: Can I pay in RMB with 支付宝? A: Yes, but N1N converts at their exchange rate. You’ll lose 2-3% compared to paying in USD. USDT avoids this entirely.
Q: What happens to unused balance if I stop using N1N? A: No refund policy is specified. Assume pre-paid balances are non-refundable. Start with the free trial before recharging.
Q: Is there a minimum recharge amount? A: Not publicly documented. Contact N1N support directly — I couldn’t find this in the dashboard after registration.
Q: Does N1N support batch processing discounts? A: No. Pricing is per-token with no volume tiers. Each request is billed at the same rate regardless of total usage.
