The expansion of OpenRouter models from 63 to 668 sounds big, but saying the tracking itself caused it feels a bit like saying the weather report makes it rain.
Here in the Netherlands, we might track how many people use a certain bike path, but that data helps us plan, it doesn't magically make more people cycle. People ride bikes because the infrastructure supports it and it's efficient.
Similarly, model availability likely grew due to innovation and market demand, not just someone counting them.
It's a useful report, but the underlying drivers are what really make the difference.
