AI model updates on September 20

Thank you for using Oz Chat.

To maintain stable conversation quality as older AI models reach the end of service, we will update our chat AI models at 4:00 AM JST on September 20, 2026.

What is changing

• Amaama 2 will end, and Amaama 2.1 will become the default version.
• Amami 1.1 is available for early selection starting August 20 and can be used alongside Amami 1 until the September 20 update.
• Amami 1 will then end and be updated to Amami 1.1.

If an ending version is currently selected, it will switch to its successor automatically after the effective time. No action is required.

What stays the same

Your chat history, MP balance, subscription prices, and MP-free upper-model uses for Boost Plus and Boost Max will not change.
