Hi @nejib1 — thanks for maintaining this great list! 👋

Gentle bump on this PR. We added Yingsuan AI as a free/open LLM API gateway. We've since onboarded Moonshot K3 (Kimi K2) — the 2.8T-param open-source MoE model that just topped the Frontend Code Arena (#1 globally) and whose full weights drop on July 27. We're exposing it via an OpenAI-compatible endpoint at a flat low price, which has been getting real traction in the open-source community.

No rush at all — just wanted to make sure it didn't fall through the cracks. Happy to adjust the entry (name/category/description) however you'd like. Thanks for your time!

Update: Yingsuan AI now has two data products listed on the Yunnan Data Circulation Trading Platform (provincial data exchange): LLM API Gateway and AI Computing Scheduling Service. Both passed the platform's registration and listing review.

The English API docs page and GitHub READMEs have been updated to reflect the dual-node listing. Please let me know if any additional information is needed. Thanks!
