As answered by people managing Killbill and you.bot.
you.bot's answer:
you.bot gives you 80+ AI models — LLM, image, video and music — behind a single API, priced well below the official APIs: up to 80% less, from $0.0046 per call. Verified examples versus official list price include Grok Imagine 1.5 video at $0.0178 per second (-78%), GPT Image 2 at $0.0564 per 1K image (-74%) and every current frontier text model at 43-51% off. You only pay for successful generations (failed or empty runs are auto-refunded) and credits never expire, so you get the same top models for less without maintaining a separate SDK and bill for each provider.
you.bot's answer:
Price and flexibility. Instead of calling each provider directly, you.bot runs the same top models for up to 80% less from one prepaid wallet — Grok Imagine 1.5 video at $0.0178 per second, GPT Image 2 at $0.0564 per 1K image, Claude Sonnet 5 at $1.5367 per million input tokens — and only charges for successful calls (failed or empty runs are refunded). You can keep your existing provider key as a fallback route, so you capture the savings without betting reliability on us, and switching between 80+ models is a one-line change.

Hi, I own a small online business and was wondering if anything knew of a good online billing platform, hosting for recurring payments. I saw one online (killbill.io) but I was wondering if there was any other alternatives around. Thanks! Source: over 3 years ago
Great list, thank you. One option is to always have more than one payment processor activated. Splitting payments across providers early on doesn’t have to be a bad thing. There are libraries focused in billing and payment management... - Source: Hacker News / over 3 years ago
