NanoGPT Subscription vs. OpenRouter: The Kimi-K2.5 "Quality Gap"
I’ve been testing Kimi-K2.5 for agentic tasks using OpenClaw, and the difference between using it via a NanoGPT subscription ($8/mo) vs. OpenRouter (Pay-As-You-Go) is night and day.
Here is what I'm seeing:
The Performance - On the NanoGPT $8 plan, my metrics for Kimi-K2.5 hit:
- TTFT (Time to First Token): 20+ seconds a lot of times.
- TPS (Tokens Per Second): 3–5 TPS. On Openrouter it’s nearly instant and hits 30-50+ TPS. Is NanoGPT routing subcription account requests to heavily quantized providers to maintain their margins?
OpenClaw task completion
- OpenRouter: Tasks are implemented quickly. The model understands the file structure, plans the edit, and executes.
- NanoGPT (Subscription): It takes several back-and-forth "discussions" just to get it to understand the task. Even then, it often does something "silly" or flat-out wrong at the end. It feels like the reasoning capabilities are very poor compared to accessing the same model via OR.
Reliability & Timeouts I’m getting no-responses or timeouts on NanoGPT. In an agentic workflow like OpenClaw, one timeout breaks the entire chain.
My Guess: NanoGPT's routing logic for subscribers favors the cheapest possible provider (likely decentralized miners). While this is fine for basic chat, it makes the model unusable for Thinking or Agentic work.
Has anyone else compared the original vs. the subscription versions on NanoGPT?
Curious if the devs or others have noticed this massive drop in "Intelligence-per-Token" on the sub plan.
