支持多媒体模型就爽啦

这个模型用着特别方便，如果他能调用音视频创作的API就简直完美的不要不要啦，不知道开发者老师有没有相关计划。

Korrektur, 9. August 2026

. Korrektur: am 9. August 2026 gelöscht funktioniert bei mir nicht mehr Abo gekündigt. Ich vermute die Nutzer Grenzen wurden massiv geändert. Ich hätte zwar noch 2 M Token gehabt, nützt mir aber nichts mehr da die Grenzen massiv geändert wurden, gibt mir keine Antwort mehr aus irgendwelchen Gründen auch immer abgerechnet wird trotzdem.
Da ich die Ursache nicht weiß, nur ein Stern Abzug, musste mir eine andere App zulegen.
Funktioniert noch löschen und Neuinstallation gar nicht mehr. 2M guthaben, die ich noch hatte, sind auch komplett verschwunden. Hab die App wieder gelöscht.
Das mit den automatischen Blocks bei Claude wird erst ab 14. August 2026 eingeführt. Also das dürfte wegfallen, weil der 14. August noch nicht ist.👎

Love it!

I use the app with OpenRouter (BYOK). It’s very flexible, the developer is responsive and supportive. Also I really like the UI and UX. Thank you!
