Good app but poor maintained

The app has some very useful features, but there are so many annoying bugs that makes me wonder whether this app is properly maintained.

For example, the stop button is absent while LLM is making MCP tool calls.

Another issue related to MCP tool call is that the chat might stop from generating after invoking several tool calls.

无法设置全局prompt

逻辑奇怪,既不面向工程师也不面向普通人,绕一大圈用它自己的keyboard才能选择prompt,还提示无法连接服务器选不了!用户就想一个默认prompt连个p服务器!

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。开发者团队小哥哥小姐姐们咱们有支持音视频模型的宏伟计划吗

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.👎
