OpenRouter proxied Perplexity models missing

Nobody has claimed this yet.

OpenRouter proxies Perplexity models, e.g. Perplexity Sonar and variants; why aren't they listed in the models.dev list?

Reproduce:

Visit https://models.dev/?search=perplexity
Notice that the OpenRouter doesn't appear in the list

However, OpenRouter serves those models:

I have a question for the maintainers. From a VERY brief look I took at the repo, there aren't any workflows to automatically update model lists for OpenAI compatible providers? Why not just run a workflow every 24 hrs to fetch and parse https://openrouter.ai/api/v1/models, which contains pretty much all the info you need, and update the list based on that?

Thanks in advance!

Compare the OpenRouter response at https://openrouter.ai/api/v1/models with the provider data shown by https://models.dev/?search=perplexity. Confirm that Perplexity Sonar and its variants are represented under OpenRouter, then verify that the models.dev search results include them. Done means the missing OpenRouter models are listed with the available provider metadata.
