"Hey, this is one of the cleanest and most practical token billing setups I’ve seen. Really well written!
I love that you went with Kong AI Gateway + Konnect Metering instead of building yet another custom pipeline. The fact that the gateway already knows the token counts and can meter them directly is such a smart move.
The part about splitting input vs output tokens (and why it matters for pricing) is gold — a lot of people miss that and end up undercharging on output-heavy usage.
Quick questions for you:
How’s the added latency from the gateway in production? Noticeable or basically zero?
Would you recommend this stack for a smaller indie AI product, or is it more suitable once you have decent volume?
Thanks for the detailed walkthrough — saved it for future reference. Super helpful!"
In practice, the gateway hop is usually small relative to model/provider latency, so it hasn’t been the bottleneck in my experience. Kong’s docs also call out that Gateway and AI Gateway are designed for minimal and predictable latency, but I’d still benchmark with your own setup (plugins, traffic, provider mix) since that’s what really determines impact.
Yeah, I think it can make sense earlier than most people expect, if you already know you need a gateway boundary, provider abstraction, per-consumer usage tracking, and usage-based billing.
AI Gateway gives you a consistent layer across providers, and Konnect Metering & Billing handles usage tracking, pricing models, subscriptions/invoicing, and limits on top.
If it’s a very small app with a single provider and you just need basic cost visibility, this might be more than you need initially. But once you care about attribution, enforcing limits, or monetizing usage cleanly, doing it at the gateway layer is a lot simpler than pushing all of that logic into app code.
