Hear from Andrej Karpathy on how Tesla is using PyTorch to develop full self-driving capabilities for its vehicles, including AutoPilot and Smart Summon. I hope you find this video informative.

And even said without hesitation that the NNs were being built specifically for HW3...so absolutely YES.I get the impression from the video that Tesla definitely has more advanced NN designed for the AP3 computer than we don't have in the AP2 and AP2.5 cars. I just look at the videos that Karpathy showed for Smart Summon for example and it seems like he is showing something better than what we have,
So dojo is a CPU optimized for training their NN
It looks pretty modular. They run multiple (8?) Resnet-50 style "backbones" which pass their output to a bunch of subtasks. They train each subtask to perform a certain function - e.g. traffic light recognition, pedestrian recognition, depth estimation, etc. They can retrain one subtask without affecting the others. They can also add new features by adding backbones and/or subtasks, up to the limit of the FSD chip.I get the impression from the video that Tesla definitely has more advanced NN designed for the AP3 computer than we don't have in the AP2 and AP2.5 cars.

Dojo will resemble cloud TPUs. Here is some info on TPUs:
Cloud TPU breaks AI inference records | Google Cloud Blog
In Karpathy's latest talk he said their ML stack resembles ResNet-50 (2:50). You can use that when looking at the performance graphs.
Yes and it will make it easier to train larger more complex models. They will load it with a ton of ram, cache ram and link the Dojo TPUs together.
According to Karpathy the goal of Dojo is to bring down the cost(could mean energy, dollars, time) to train large scale NN for Tesla a factor of 10x.In layman's terms, will Dojo basically speed up the NN training process?
The cost for electricity is trivial compared to other costs....
My guess is that they are referring to energy, which will correlate with dollars. ...
Seems that you are correct. ThanksThe cost for electricity is trivial compared to other costs.
