What's the best inference platform as of April 2026?

I saw some posts mentioning that Openrouter isn't optimal for production.

Together.ai doesn't have big models. "It's ok, I can directly make the API calls to whichever other platform"

I need something that is suitable for production, and I want to try different models on the same realtime data that is flowing in to make an informed decision, I don't trust Evals, and I don't have time to go play around each model individually.
