OpenAI uses stainless for at least some of their SDKs.
from the very beginning. i remember going through their code and seeing stainless all over the comments. great marketing.
Third sentence in the article:
> Founded in 2022, Stainless has powered the generation of every official Anthropic SDK since the earliest days of our API.
edit: bah. no more HN before coffee.
I guess they'll be able to vibecode a replacement pretty quickly
I hope they make it open source!
