The explosion of Chinese AI models has created a fragmented ecosystem. DeepSeek, Qwen, GLM, MiniMax, and others each have their own API endpoints, authentication systems, and pricing — making it a nightmare for developers who want to use them all.
API gateways solve this by providing a single OpenAI-compatible endpoint that routes to multiple models. Among the most popular options for Chinese model access are AI Nexus (tokencnn.com), OpenRouter, DeepInfra, and Together AI. Each takes a different approach to model hosting, pricing, and developer access.
In this comparison, we evaluate each provider specifically for international developers who want to access Chinese AI models without needing a China phone number, Chinese payment method, or complex registration process.
2. Provider Overview
Here's a high-level comparison of the four providers:
| Feature | AI Nexus Best | OpenRouter | DeepInfra | Together AI |
|---|---|---|---|---|
| Founded | 2025 | 2023 | 2022 | 2022 |
| Focus | Chinese AI models for global devs | General model router | Inference infrastructure | Open-source model hosting |
| Chinese Models | DeepSeek, Qwen, GLM, MiniMax, Yi, Baichuan, ERNIE | DeepSeek (limited), Qwen (limited) | DeepSeek only | DeepSeek, Qwen (limited) |

| OpenAI-Compatible | ✓ Yes | ✓ Yes | ✓ Yes | ✓ Yes |
| Free Tier | Free credits on signup | Free tier (limited) | Free inference (rate-limited) | Free credits on signup |
| PayPal/Crypto | ✓ Yes | ✗ No | ✗ No | ✗ No |
💡 AI Nexus is the only provider specifically built for international developers who need access to Chinese AI models — DeepSeek, Qwen, GLM, MiniMax, Yi, Baichuan, and more — through a single API.
3. Chinese Model Coverage Comparison
This is the most critical factor for developers looking for a Chinese AI API comparison. Most providers only offer DeepSeek and maybe Qwen — AI Nexus has the widest coverage by far.
| Chinese Model | AI Nexus Best | OpenRouter | DeepInfra | Together AI |
|---|---|---|---|---|
| DeepSeek-V4 Pro | ✓ | ✓ | ✓ | ✓ |
| DeepSeek-R1 | ✓ | ✓ | ✓ | ✓ |
| DeepSeek-Coder | ✓ | ◐ Limited | ✓ | ✓ |
| Qwen-Max | ✓ | ◐ Limited | ✗ | ✗ |
| Qwen-Plus | ✓ | ✓ | ✗ | ✗ |
| Qwen-Turbo | ✓ | ✓ | ✗ | ✗ |
| GLM-4 | ✓ | ✗ | ✗ | ✗ |
| GLM-4-Flash (Free) | ✓ | ✗ | ✗ | ✗ |
| MiniMax-Text | ✓ | ✗ | ✗ | ✗ |
| Yi (01.AI) | ✓ | ✓ | ✗ | ✓ |
| Baichuan | ✓ | ✗ | ✗ | ✗ |
| ERNIE (Baidu) | ✓ | ✗ | ✗ | ✗ |
💡 AI Nexus offers 14+ Chinese models from 7+ Chinese AI labs. OpenRouter covers only 4 Chinese models, DeepInfra covers just DeepSeek, and Together AI offers DeepSeek + limited Qwen. AI Nexus is the clear winner for Chinese model breadth.
If you're looking for OpenRouter alternatives specifically for Chinese AI models, AI Nexus is the most complete choice — it offers models from Chinese providers that OpenRouter simply doesn't route to.
4. Pricing Comparison
Pricing varies significantly between providers due to different markup strategies. We compared the cost of popular Chinese models across all four platforms (prices in USD per million input tokens):
| Model | AI Nexus Cheapest | OpenRouter | DeepInfra | Together AI |
|---|---|---|---|---|
| DeepSeek-V4 Pro | $0.21 | $0.28 | $0.25 | $0.25 |
| DeepSeek-R1 | $0.83 | $1.12 | $0.95 | $0.95 |
| Qwen-Max | $0.60 | $0.80 | — | — |
| Qwen-Plus | $0.12 | $0.16 | — | — |
| Qwen-Turbo | $0.05 | $0.07 | — | — |
| GLM-4 | $0.30 | — | — | — |
| GLM-4-Flash | FREE | — | — | — |
| Yi-Large | $0.15 | $0.18 | — | $0.18 |
💰 AI Nexus is 15-33% cheaper than OpenRouter on every comparable model. For high-volume usage, the savings add up to hundreds or even thousands of dollars per month.
DeepInfra and Together AI compete on DeepSeek pricing but simply don't offer most Chinese models. If you need Qwen, GLM, or MiniMax — and want the best DeepSeek API provider pricing — AI Nexus is the most affordable option across the board.
5. Payment Methods
For international developers, payment flexibility is a major factor in choosing an API provider. Chinese model providers (DeepSeek, Alibaba, Zhipu) typically require Alipay or WeChat Pay with a Chinese bank account — a barrier for most global developers.
| Payment Method | AI Nexus Best | OpenRouter | DeepInfra | Together AI |
|---|---|---|---|---|
| Credit/Debit Card | ✓ | ✓ | ✓ | ✓ |
| PayPal | ✓ | ✗ | ✗ | ✗ |
| Cryptocurrency | ✓ | ✗ | ✗ | ✗ |
| Alipay | ✗ | ✗ | ✗ | ✗ |
| WeChat Pay | ✗ | ✗ | ✗ | ✗ |
💡 AI Nexus is the only provider that accepts PayPal and cryptocurrency. OpenRouter, DeepInfra, and Together AI all require standard credit/debit cards only. For developers in regions with limited card access, this is a game-changer.
Beyond payment, there's another barrier unique to Chinese AI services: phone verification. Most Chinese API providers require a China mainland phone number (+86) for registration. AI Nexus is the only gateway that completely eliminates this requirement — sign up with any email, pay with PayPal or crypto, and start building immediately.
6. Developer Experience & Ease of Use
All four providers offer OpenAI-compatible APIs, which means changing providers is often as simple as swapping the base URL and API key. But there are important differences in the developer experience.
API Compatibility
Every provider in this comparison supports the OpenAI chat completions format. Code migration between them is trivial:
client = OpenAI(
api_key="sk-nex...your-key", # Your API key
base_url="https://www.tokencnn.com/v1" # AI Nexus endpoint
)
Registration Friction
| Requirement | AI Nexus | OpenRouter | DeepInfra | Together AI |
|---|---|---|---|---|
| Email signup | ✓ Instant | ✓ Instant | ✓ Instant | ✓ Instant |
| Phone verification | ✓ Not required | ✓ Not required | ✓ Not required | ✓ Not required |
| Free credits on signup | ✓ Yes | ✓ Yes | ✓ Yes | ✓ Yes |
| No payment method needed | ✓ Yes | ◐ Limited | ◐ Limited | ✓ Yes |
Documentation & SDK Support
All four providers offer solid documentation and work with the official OpenAI SDK for Python, Node.js, Go, Java, and curl. AI Nexus stands out with Chinese-language-specific guides, model recommendation guides, and example code for every supported model.
Rate Limits & Concurrency
OpenRouter applies a dynamic rate limit system based on your spending tier. DeepInfra offers generous free tier rate limits. Together AI provides dedicated capacity options. AI Nexus offers the most flexible rate limits with automatic scaling — no pre-approval needed for higher throughput on popular models.

8. Unique Selling Points
AI Nexus — The Chinese AI Gateway for International Developers
🇨🇳 "No China Phone Number Needed"
The single biggest friction point for accessing Chinese AI models. Every Chinese provider — DeepSeek, Alibaba (Qwen), Zhipu AI (GLM), MiniMax, Baidu (ERNIE) — requires a mainland China phone number (+86) for registration. AI Nexus eliminates this completely. Sign up with any international email, fund your account with PayPal or crypto, and access all Chinese models through a single API.
🌍 "Chinese AI Models for International Developers"
AI Nexus is the only API gateway purpose-built for international developers who want Chinese AI models. While OpenRouter and DeepInfra are general-purpose routers that happen to offer a few Chinese models, AI Nexus specifically curates and optimizes access to DeepSeek, Qwen, GLM, MiniMax, Yi, Baichuan, and ERNIE — all through one OpenAI-compatible endpoint.
💳 PayPal & Cryptocurrency
Even the "developer-friendly" Chinese AI providers like DeepSeek require Alipay or WeChat Pay, which need Chinese banking. AI Nexus accepts international credit cards, PayPal (available in 200+ countries), and cryptocurrency (BTC, ETH, USDT). This is a unique advantage that no other Chinese model gateway offers.
🆓 GLM-4-Flash — Completely Free
Only AI Nexus offers Zhipu AI's GLM-4-Flash at zero cost. It's a capable model for prototyping, chatbots, and light production use — and it supports function calling and streaming. No other gateway in this comparison offers a free Chinese model.
🔌 True Drop-in Replacement
Since all providers use the OpenAI-compatible format, switching is easy. But AI Nexus goes further — it maps Chinese model names to intuitive identifiers (e.g., deepseek-chat, qwen-max, glm-4-flash) that just work. No confusing provider prefixes or model version strings.
9. Final Verdict & Recommendation
After a thorough comparison across model coverage, pricing, payment methods, developer experience, and unique features, here's our recommendation by use case:
