it's wild to me how far we've come without memory in our policies, but see pi.website/research/memory for how it unlocks long-horizon and partially observable tasks
the secret sauce is doing it efficiently and over varying horizons, but otherwise, at scale, it kind of just works!
We’ve developed a memory system for our models that provides both short-term visual memory and long-term semantic memory.
Our approach allows us to train robots to perform long and complex tasks, like cleaning up a kitchen or preparing a grilled cheese sandwich from scratch 👇
