Børnich: NEO will operate independently with embodied AI, functioning autonomously for most tasks. However, for advanced long-term reasoning and planning, it initially relies on external cloud-based models, like those from OpenAI. This means reduced functionality without cloud connectivity.
A standard broadband Internet connection suffices for this cloud interaction, ensuring NEO accesses its full capabilities when connected.
