I'm not entirely sure what a physical LLM is. Would you care to elucidate how they work and when they're likely to be doing my gardening?

Sure physical LLMs are when an LLM is trained on data where it outputs control bits for actuators on an actual humanoid robot instead of text like you see in a chat bot.

How likely are they to do your gardening if you ask me I would optimistically say within the next six months. For examples of working instances of this look up Figure robotics they’ve had live streams where it sorts mail and cleans houses although the cleaning of the houses is very early stage, and it kind of only does contrived situations. Look up Sunday robotic’s live stream where they literally have a 99% accuracy on folding nine different types of garments. Look up Unitree where they’re making progress on a person asking a robot to do something and it coming up with a novel action on the fly.
