Confirmed: Voice recognition local processing for R1 (Gen 1 and Gen 2). The R2 will have a local LLM.

The fun part: when Rivian tries to do all this through a complex LLM setup that ends up performing worse and less predictably than old tech (for way more money).

Just like every LLM-based "solution" to a problem that I see Product Managers and execs pushing at work today. Fantastic.

I think you’re conflating two separate Rivian claims.

Rivian’s R2 media material places the 200 sparse TOPS figure under the R2 infotainment compute module. RAP1 is described separately as part of the Gen 3 Autonomy Computer, which Rivian rates at 1600 sparse INT8 TOPS (using a pair of RAP1 modules).

200 sparse TOPS under typical 2:4 sparsity, is roughly 100 dense TOPS. That puts it closer to modern high-end smartphone SoC territory than an autonomy-class accelerator.

That is still good hardware for an infotainment system. I just think Rivian’s AI marketing would be clearer (and of course they know this too, and are clearly intentionally being ambiguous) if they stated the dense-equivalent performance, precision, memory, etc. Considering the last information SOC was mediatek (if I recall correctly) then this could simply be that they moved from that, the CV5 and another pair of supporting SOCs (WiFi and GPS?) to something like https://www.mediatek.com/products/smartphones/mediatek-dimensity-9500 and are just going full AI,AI,AI,AI on how they describe this.

100%. You right.

Basic voice recognition for baked commands requires ridiculously little processing power. My computer in 1999 could do it. Cars in the mid '00s could do it.

No, you won't get LLMs, you probably won't even get "complex commands." But "lower temperature to 69 degrees" won't be a problem. "Open tonneau" shouldn't be a problem. (Although my 2016 Tesla Model S with MCU2 still can't do simple things like "open the sun roof", that's on Tesla for not programming in the basic commands.)

It wont open the sunroof because the only way to do that is with a hammer. No option for an openable sunroof on 2016 Tesla.

My 2016 would disagree with you.

As would tons of public documentation showing that Tesla discontinued it in 2018.

Who cares how the processing is done? I want to be able to tell it to find a destination reliably and to send and receive texts. That would be a good start.

However technically qualified folks may be in the forum, we’re the customers, not the engineers, here. We should stay focused mainly on the ”what,” perhaps on the “why,” but the “how“ is merely a matter of curiosity.

My late 2016 P100D Model S also disagrees with you.
