What this post added

This post details how Nous Research implemented Vercel BotID Deep Analysis to protect their AI chat application during a free tier promotion. Key technical details include: layered checks at the portal (Auth Flow) before and after sign-up/sign-in, and at the chat UI layer with a heartbeat mechanism and cached verification for inference requests. It also highlights BotID's ability to detect and mitigate a coordinated attack characterized by specific IP patterns, geographic origin, and JA4 hashes, preventing a 3,000% traffic spike from impacting inference and availability.
