Link: With aff, it seems to be 99; without it, it’s 50
AFF Includes AFF OpenCSG

OpenCSG
API endpoint: https://ai.space.opencsg.com/v1
Visit this link to immediately receive 99 yuan; without the invitation, you get 50 yuan.
The speed is pretty good too. That 99-yuan big catch should last me quite a while.

Models:
DeepSeek V4.1 Flash, DeepSeek V4 Pro, Kimi K3, GLM-5.3-Flash, Qwen3.8-Flash, Qwen3.8-Max, and other Chinese models are available.

Notes:
The funding history is clear: Seed round (2023-03) → tens of millions of yuan in the angel round (2023-09, Lenovo Capital, Beijing Guoxin Zhongshu, Zhongke Shengzhe) → several hundred million yuan in the Pre-A round (2026-08, Jing’an Capital, Shibei Hi-Tech, Xuhui Capital, Huanghai Financial Holdings). The post-investment valuation has entered the unicorn range. The investors are primarily Shanghai state-owned capital, and the funds are intended for open-source AI infrastructure, Agentic AI platforms, and city-scale AI infrastructure.
API access is in the account settings!

Which key am I supposed to enter?

What’s most disgusting is this kind of deceptive promotion.
Even though new users get a 100-yuan credit just by registering, you’re still here falsely claiming that it’s 50 without using an invitation…
And the model is completely unusable—I encountered frequent errors on my very first call.

The one in the middle.

I sent it an hour ago, and I’d already used up my quota. Now you’re telling me it’s restricted—why didn’t you notice earlier? I have two accounts. The first one I registered myself, and it’s only 50 yuan. It says AFF above; you can just remove my AFF and that’ll solve it. You’re also saying I scammed you—if I scammed you, why did you go ahead and use it? Aren’t you just being ridiculous?

People like you take the eggs and then complain that they’re dirty. If you don’t want the eggs, why take them in the first place? You could just pay directly and use the official API.

Feels like I can’t keep getting this for free, so I won’t bother with it anymore. Thanks for sharing.

Please take a look, thanks.

13

That’s strange—why can’t I use k3?

14

Huh? There isn’t even a k3 in it.

15

Ah, I didn’t look closely. I saw “k3” in your title, so I clicked in. What are you all using—4.1?

16

Hey, buddy, where does the title say K3?
