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!
