I’d be most interested in how it handles uncertainty when the answer depends on trim/year or service history. For a car assistant, a useful default might be “I found the relevant manual section, but this is ambiguous” rather than a direct fix. Do you surface the source page or confidence anywhere?

#63I'm currently integrating one for simple diagnostic readouts to integrated small touchscreen. The main goal being a retro looking display that mainly dumps ODB data/monitors, but also reads maps data to show a "waypointer" a la crazy taxi. (This is proving difficult) Respectfully, I don't think this is....real? -I mean, getting the absolute basic bits like diag codes converted from the odb 2 data to some program w/ a…
From readme: """ Unverified against the real car — it will confirm or refute itself on the next drive """ Looks like a ton of this is aspirational. For your project -- do you really need the car's GPS positioning? Could go with a dedicated GPS antenna, like the freematics dongle

#64Cool — but is that model really the right choice for the task? I guess it is only 3B active which helps a lot but is Gemma 4 E4B not more practical?
It was a very tight fit!

#65I scanned this README looking for the part written by a human and gave up when I realized there wasn't one. the Mermaid diagram doesn't even render.

#66What's the hardware situation to get OBD data?

#67Earlier quoted context omitted.
I've been very impressed by it's intelligence and lack of hallucinations. The dynamic Q3 is a good balance between accuracy and size keeping the 35B just below 16 GB. It is not supposed to know everything, it is your car. It actively disengages from off topic chatter (too slow for that anyway), better spend that time feeling the car. It keeps itself grounded on sensor input. One principle per wheel. assert only what…
> . The dynamic Q3 is a good balance between accuracy and size keeping I'm having a hard time understanding how you find any sort of accuracy in Q3, when I use it with BF16 and it's hardly usable due to drastic hallucinations and inability for system prompt following. But, if it works for you, that's pretty good! Guess I'm jealous :)

#68I think you should provide better use case scenarios that make clear why this project is useful. I can already change AC and lock doors with two buttons, why it should be better to do it by voice? Pressing those buttons is way faster. I guess the manual RAG is useful, what I am saying is that use cases aren't clear from your post or README. As it is, one reads it as "cool, LLM in a car", and skips it.
Re: Show HN: I made a Raspberry with Qwen my local car AI
#69At one point, every machine on earth is going to be its own agent, asking and answering questions and expressing concerns. Its like a good example of that, but I think the utility of it needs to be clear, by making some action a lot more convenient or even better, by solving a structural impossibility - what is it that you can do with an agent mounted in a car that you otherwise can't? That seems like a much stronger…

#70> stuff like changing AC Maybe it's different in the People's Republic of Europe or wherever, but either that's a translation error or I don't understand, but I would be interested to see how quickly the EPA gets mad when Claude tells you to recover your R134a to the atmosphere.
Anyway here I meant activating heating / cooling before you step in the car, as determined by your agent family who understand you well and not requiring any "AC on!" commands from you. i live in Finland and preheating is very useful in the winter
