Details
Erxin (尔信) lets you access AI models via API at aierxin.cc. It advertises rates lower than official pricing: compared with official rates, the GPT mixed-account pool is priced at 0.08x, the GPT-pro own-account pool at 0.25x, and the Claude-max own-account pool at 1.2x. A promotion adds an amount equal to your top-up, so topping up 10 dollars gives you 20 dollars to use, topping up 20 dollars gives you 40 dollars, and topping up 50 dollars gives you 100 dollars.
Join QQ group 726533341 (Erxin_AI) first, then sign up and ask customer support to apply the benefit. You can check performance before paying using the free trial credit you receive right after registration.
There is no cap on the additional amount granted. You can use twice the amount you top up, cutting the effective rate in half. The QQ group distributes free-use keys in limited quantities every day, and also gives away keys loaded with larger amounts at no set time.
