- Fixed AI Studio asking such a server for its models with an empty key attached when you had stored none at all. Servers behind a login turn those requests down.
- Fixed a key that could not be saved going unmentioned for the servers you host yourself. You are now told what went wrong, instead of the settings simply staying open.
- Fixed transcripts quietly losing what was said softly, such as a greeting at the very beginning of a recording. AI Studio compressed recordings so far before sending them to your transcription provider that the model could no longer make out those passages. Recordings now keep enough details for the whole of what you said to arrive.
- Fixed AI Studio seeming to hang for minutes when a chat had grown too large for the model. Some providers turn such a request down in a way AI Studio did not recognize, so it kept sending the very same oversized request again and again before giving up with a message that explained nothing. It now tells you right away that the chat, including its attachments, is too large for the selected model.
- Upgraded the Visual Briefing assistant (in preview) from the prototype to the beta state. The assistant is now completely implemented and is undergoing a deeper testing phase in preparation for release. To try it, open the app settings, allow preview features down to beta, and then enable the Visual Briefing assistant there.
- Upgraded the vector database behind local RAG (Qdrant Edge) to version 0.8.0.
