Where LaoZhang.ai fits
LaoZhang.ai has built real trust with Chinese-speaking developers: deep discounts, payment rails that work in China, responsive group support, and a blog that answers almost every pricing/how-to question in the space. For an individual developer in that ecosystem who wants the lowest headline price and reads the docs in Chinese, it is a natural pick.
Where Kunavo wins
Kunavo is built to be auditable and global. The catalog is public — every model's per-1M-token USD rate sits next to the provider's official price, so procurement can verify the 30–70% discount without joining a chat group. Billing is Stripe-native with local methods (Pix, WeChat Pay, Apple/Google Pay, ACH/SEPA) and real invoices; failed requests are never billed; Claude runs on the native Anthropic Messages API as well as the OpenAI-compatible endpoint; and the same key generates images, video and music. For a team that needs compliance-friendly payments and predictable token economics, that package is the differentiator.
How to pick
Pick LaoZhang.ai if you operate in the Chinese-speaking ecosystem, want the most aggressive headline discount, and are comfortable with relay-style operations. Pick Kunavo if you want a published catalog you can audit, Stripe billing your finance team accepts, the native Anthropic API, and multimodal generation on one wallet. Either way, both are OpenAI-compatible — switching later is a base_url change, so start with the one whose billing story matches your team.
