# Tavus shows Raven-2, faster perception with visual memory for PALs [View media]() 0:000:00 Tavus released a video on [Raven-2](), the perception model that lets a PAL see faster and remember what it saw earlier in a conversation. The model has been in Tavus's developer changelog since October 23. Tavus says Raven-2 processes camera and screen content about 3x faster than the model before it. It also keeps a visual history of the call, so a PAL can refer back to objects, pages and errors that are no longer on screen. The docs give questions like "What was the previous error?" and "Which object did I hold up first?" as examples. That history is built automatically and covers a single conversation. Raven-2 also adds dedicated screen perception, which starts once someone shares their screen, and lets a PAL speak up about what it sees on camera while you're quiet. It's opt-in. Raven-1 is still the default, and you switch a PAL over by setting its `perception\_model` to `raven-2` and starting a new conversation.
