A Chinese-built comparison site for proxy stations. GPT-5.4/5.5 API at 96–97% off official pricing — that's what's openly sold on China's second-hand marketplaces. Not a scam — I've benchmarked them, they're real frontier models. I'm a CS student in China and pretty new to Reddit. I've been browsing r/ChatGPT, r/ClaudeCode and r/vibecoding lately, reading threads about AI tools being too expensive — Claude Code hitting the 5-hour Pro rate limit in under 20 minutes, etc. As a developer living in a completely different ecosystem, I thought my experience might be interesting. On Xianyu and Taobao (China's equivalents of eBay and Amazon), vendors openly sell GPT API access at around 0.2–0.3 RMB per USD of official pricing (~3–4% of official; Claude is pricier at 10–20%). My schoolmates and I use these daily, burning 100M+ GPT-5.4 tokens for about $1. My daily setup I vibe code with GPT-5.4 and Opus 4.6 (I prefer 4.6 over 4.7) every day. Payment through WeChat or Alipay, no complicated setup — the proxy station's API handles everything, including crossing China's Great Firewall. Among programmers and CS students I know, adoption is close to 100%. It's as normal as using GitHub. Engineers at some of China's largest tech companies also use proxy-routed Codex/Claude Code for non-sensitive work. Why not Chinese models? GPT-5.5 and Opus 4.7 are generally considered stronger than the Chinese alternatives for coding. But here's the real surprise — on the grey market, GPT is almost as cheap as DeepSeek. When the best model costs about the same as the budget option, most developers I know pick the best. Some still use domestic models, but the grey market has shifted the default choice. What this market looks like Proxy stations operate openly on Xianyu and Taobao, and QQ (China's Telegram). Operators use open-source tools (many available on GitHub) to convert mainstream AI subscriptions into standard API endpoints, then build account pools and redistribute access at scale. The market has developed price-comparison sites and quality-testing platforms tracking each proxy's uptime, latency, and pricing (see image). Major stations run QQ after-sales groups with tens of thousands of members who actively review service quality. They operate as brands, with some surviving over six months. How it's so cheap It's arbitrage. OpenAI gives paid subscribers access to Codex with generous quotas — more than 10x the subscription cost at API rates. People reverse-engineered the Codex interface into a standard OpenAI API proxy (search GitHub for CLIProxyAPI), then stack subscriptions from low-price regions like the Philippines and zero-cost ChatGPT Plus trial to drive costs down further. Claude is a different story — Anthropic's security is much tighter, so grey-market Claude runs at 10–20% of official API pricing, significantly more expensive than GPT's ~3%. The catch Data privacy — your code passes through the proxy's servers. Rumors say some operators sell interaction data to domestic AI labs for distillation and LLM post-training. Reliability — accounts get banned constantly; operators keep replenishing the pool. The prevailing attitude: "I already gave my data to OpenAI/Anthropic — what's one more middleman?" Final thought When the black-market price drops to 3% of official, it points to a massive arbitrage gap in the pricing structure. This is a mature supply chain. Nearly every developer and CS student I know is on it — including engineers at some of China's largest tech companies.

Like you said they're definitely stealing your data
u/Solution_Better · 14 pts
Just wanted to say the same. Very elaborate schema to get your IP
u/vevi33 · 8 pts
Thankfully American companies like Google, Meta, Open AI and Anthropic doesn't... Oh wait...We need to care about privacy, but the only reliable option long term is using local models unfortunately.
u/FieraPosting · 5 pts
I'd rather the Chinese have my data than the Americans.
u/Particular-Award118 · 2 pts
You're in luck then cause both already do
u/blueberrywalrus · 14 pts
That's not arbitrage, but certainly an interesting dynamic. This is purely people defrauding Claude/OpenAI by buying a non transferable license and letting others use it. It'll get cracked down on eventually.

The high seas will always have waves.
u/ranger910 · 5 pts
They use stolen accounts and they swap out high end models with cheap ones while telling the user they are using Opus 4.7. OP is either a moron or they know and are just shilling for the scammers.
u/No-Chance-6828 · 4 pts
True for small vendors — model swapping is a known problem. There have been cases of Sonnet or even GLM being mixed into Opus responses. But the larger proxy stations have QQ groups with 10,000+ users actively monitoring output quality. Get caught swapping models once, you lose your entire customer base overnight. So the bigger players are actually incentivized to stay honest. What's interesting is the market is trending toward legitimacy — third-party uptime monitoring, independent benchmark testing, business invoices, structured customer support. It's a grey market developing its own consumer protection ecosystem.

Very interesting post. Now the real question. Can I somehow use these 95%+ discounted models from the us?
u/99kmph · 3 pts
can I use this as someone living in the US?
u/No-Chance-6828 · 3 pts
I'm working on bridging that gap though — DM me if you're interested in testing.
u/No-Chance-6828 · 1 pts
Technically yes, unfortunately most Chinese vendors don't support US payment methods yet ：（
u/Revelation12Studios · 2 pts
Grey market? Sounds shady.
u/The_gibbing_tree · 2 pts
Could not be a more obvious scam.
u/Fluffy-Acadia-6093 · 2 pts
Is this worth it?
u/No-Chance-6828 · 4 pts
Xianyu Claude vendors vary wildly in quality. Stick to providers with 1,000+ member QQ after-sales groups. Larger community = more oversight = less fraud.
u/itzCH_ · 2 pts
so you know where I can find trustable vendors? Like I know how to use xianyu and taobao but how can I know if the seller is trustable?
u/Reksum · 2 pts
Ironically, I (in the US) just started switching over from claude.ai to chat.z.ai to get more free usage. It's like that meme with the cars passing each other...

I have been using these for years. I remember when LinkApi was just a basic white frontpage and for support you had to message the guy in Telegram. Many are actually legit, although personally I prefer the reliability of paying a $20 subscription to another "gray" provider who gives me access to several models in one go. That said, I'm currently looking for a reliable provider for API GPT image 2. Do you know any OP? This one is more challenging because you need a verified organization for this.
u/rndanime · 2 pts
Can you recommend a provider for gpt 5.5?
u/daylightsun · 2 pts
Now how do I as an American purchase one of these keys?
u/sams8com · 1 pts
dm me as you can use the keys from anywhere and can even resell it white labelled
u/ShreeyanxRaina · 2 pts
Honestly I don't really care of my work is being sold as training data because in honestly nothing will happen to me it's a fair trade for these dirt cheap prices
u/lallu__lalla_ji · 2 pts
Please help me understand, How the F you manage to burn 100M tokens a day?? MF be curing cancer or what!?!
