SHORT ANSWER
On-device AI can keep core behavior responsive, reduce data transmission, and preserve a pet when connectivity fails. It does not automatically guarantee privacy or permanence: apps may still sync data, models need updates, and hardware can be locked to a vendor.
What can stay local
Wake words, simple speech recognition, vision features, behavior selection, memory retrieval, and smaller language models can run locally on suitable hardware. Products should document which features do.
Resource constraints
Battery, memory, heat, and compute limit what a pet can do continuously. Efficient models and event-driven sensing can matter more than headline parameter counts.
Hybrid designs
A pet may use local behavior and a cloud service for optional complex requests. Clear fallbacks prevent the character from disappearing when the network does.
Verify privacy claims
Local processing should be supported by network controls, permission disclosures, retention settings, and independent testing. “On-device” for one feature does not describe the entire product.
