OpenRouter listing ↗

Models observed with this app

Early adopter — relationship first observed within 30 days of the model's OpenRouter listing. First-observed dates are when Sightings first saw the pairing, not the start of an app's model usage. Last observed is the latest recorded model-page evidence for each pairing. An observation does not establish continued or exclusive usage, or reveal the app’s full private infrastructure.
