This is one of the biggest updates yet for Astro Mobile. A brand new conversation system, smarter models, and voice interactions make Astro feel more alive than ever.
🧠 Smarter Models and Systems

Added ModelA 9-Nano and ModelA 9, bringing faster, more natural conversations. (Depreciated ModelA 8-Nano and 8.R-Pro.)
-
The mode service has been unified, meaning all models now run under one consistent system.

Introduced Deep Consideration Mode, allowing all models to take extra time for more thoughtful, higher-quality responses.
-
Complete rearchitecture of token counting and usage, making it more accurate and reliable.
🗣️ Voice Mode (Beta)
You can now talk to Astro and hear it respond using the new Voice Mode.
It’s designed for smooth, flowing conversations and will keep improving with each release.
⚙️ New Tools and Features
