Layla offers the ability to switch "base models". A "base model" is the "brain" of Layla, and it powers all characters, scenes, roleplay, and all other features.
Depending on your device capabilities (see which model your device supports here), you are able to choose between several different base models:
requires at least 4GB of phone RAM
mainly used for older devices so more people can experience Layla
requires 4GB of phone RAM
an "in-between" model that balances performance with capability
requires at least 8GB of phone RAM (note this is different to phone storage)
most intelligent version of Layla
stays in character better
less prone to hallucination
only runs on flagship devices (released in the last 2 years)
Here's how to switch between base models
Starting from the character selection screen:
Click on the "gear" icon at the top right to go the "Settings" page
Scroll down to the section "Danger Zone"
Click "Switch Base Model"
Choose between the one that fits your needs
