>It’s mostly a latency problem at this point. The models are too big to run locally, but given that open-weight models like Qwen already exist, an open-weight, low latency equivalent to Astra can’t be too far out. But this is a bit of a ridiculous take, no? You don't need Astra for self-driving. Astra is able to build complex 3D worlds, do your taxes, shop for you, and, apparently, drive a car. A self-driving car just needs to be able to drive a car. By the time you trim down Astra to just have the minimum capabilities needed to drive a car, you'll be looking at the same models these self-driving car companies already use. Then you get to deal with the actual hard problems, like handling failure cases (which will still be present with Astra). >The vision stack, 3D maps, lane selection grammar, occupancy networks, it’s maybe all about to give way to a single GPT looking at camera feeds and predicting the next steering wheel adjustment. Self-driving cars have been able to do this for a long time. The problem is that it isn't robust enough given the context. I mean, if Astra can drive a car with a single camera, then presumably Astra can drive the car even better with multiple cameras, and even better than that with 3D maps, etc. And when you start to consider the expectation of performance of these systems, you realize that these features really can't be omitted. If you're a company producing self-driving cars, then you do not want to face a lawsuit for you car killing someone because it physically would have never been able to see what it was doing because it lacked a camera. I think the real gain here is that something like Astra can be used to help build these autonomous stacks. If it is able to drive itself, then it is able to generate novel data, analyze large quantities of data, and use context that isn't typically available when processing this data to make improvements to the actual autonomy stack which is ultimately responsible for driving the car. But thinking that these car companies are going to run an LLM in a car and call it a day is just naive. | ||

No, no - all that “useless” knowledge is the good stuff. There is no clean interface boundary for driving a car, because the only interface that has been enforced is “if a human can navigate this situation, it’s fine”. Real world driving situations can be arbitrarily complicated, and if you want >human level driving, you need human level semantic understanding of the world around you. If you see a kid about to throw a model airplane across the street in front of you, you have to bring all your “useless” world knowledge with you to recognize that as a developing hazard. If you’re supposed to bring your passenger to the city building on main and you encounter construction outside with a detour sign saying “for tax dropoff park in rear”, suddenly all of your useless knowledge about the English language, what taxes are, and the likely goal of your passenger given their destination become useful. | ||

The key thing Astra is doing is a loop... (my understanding) To figure out where things are... It's basically use more compute, self-driving cars are usually using on-device hardware where a "loop" might be a little too risky especially if it takes too long on local hardware... I wouldn't want my AI driving model to be over the air either, yikes in the case of lag or network outages. | ||
