I'm running it on a pi5. It was able to handle everything including voice easily although the voice thing out of the box is quite limited. I was able to do a lot with it through automations with custom commands though. It was pretty much able to replace my Google assistant system.
I've now upgraded it with ollama and Whisper on a network device (old laptop with i7 CPU and GTX1050 mobile GPU) and that works perfectly with llama3.2:3b. Pretty accurate and works well enough. Especially useful coupled with the local home assistant command processing since that by passes the LLM.
Well yes, I've installed one as well and told it to act like Marvin from a hitch hikers guide to the galaxy. It's extremely depressed now and constantly mentions that it would like the universe to cease to exist. It seems to hate me as well.
