Your point about mixing up observation with causation is so important. If we hadn't already put all this time into tracking, would we even start just to get a headcount? It's like paying to watch paint dry then claiming you caused the drying.
If we hadn't already poured time into all these model numbers, would we still be tracking them with the same attention? That expansion from 63 to 668 models on OpenRouter feels like it's missing the point of what people actually built. My uncle’s garage has 50 different wrenches, but he only uses the same three for his plumbing jobs. Just because you have a lot of options doesn't mean they're all useful, or that anyone is even paying for them.

It's a big risk when people think just watching something makes it true, for sure. You're right, just because someone 'tracked' model growth from 2023 to 2025 doesn't mean those models are actually useful for everyday work yet, or that they won't just disappear next year. What's often missing from those numbers is how many of them can even run on basic hardware without costing a fortune in server time.
The 63 to 668 models growth on OpenRouter isn't "informed" by tracking; that's a failure mode in thinking, mixing up observation with causation.
Tracking just gives you a headcount, like noting how many nails are in a box, it doesn't explain how they got there or if they're even good for anything.
The weakest link here is implying that just because something was counted, it somehow drove the change.
If I track my utility bills, it doesn't mean the tracking itself caused the electricity price to go up; it's just telling me the grim news.
OpenRouter, a leading LLM aggregator, tracks the rapid growth of available models and intelligence metrics.
Between April 2023 and October 2025, OpenRouter and Artificial Analysis documented significant increases in both open-source and closed-source models.
The number of models available on OpenRouter expanded from 63 in early 2024 to 668 by December 2025.
This data informs OpenRouter's daily research dataset, providing insights into the evolving LLM market.
OpenRouter offers a standardized API for accessing hundreds of models from various providers.
Examples
- The cumulative number of models available on OpenRouter grew substantially.
- Both open-source and closed-source models saw rapid increases in availability.
- The number of inference providers also showed significant cumulative growth.
- The intelligence index of newly released models demonstrated an upward trend.
- OpenRouter immediately integrates new models upon their release by creators.
So, tracking "model and provider growth" from 2023 to 2025 informs the claim that OpenRouter models exploded from 63 to 668? That sounds like a lot of hype.
Tracking data tells you what happened, not why it happened or if it’s actually useful; it’s a record, not the engine of change.
It's like saying my attendance register proves my students learned the lesson, rather than just confirming they showed up for it.
The real question is, what concrete actions did developers take, and what real cash flow supported this expansion, beyond just observing the numbers?
