From Perception to Driving Actions: Alpamayo on Chimera
We mapped NVIDIA's Alpamayo 1.5, a 10-billion-parameter driving model that explains its decisions and plans a path, onto four Chimera GPNPU cores in W4A16. On held-out driving clips, it writes the same reasoning as NVIDIA's reference model, token for token. Our initial release will land in Chimera SDK 26.10, and we are already working to make it faster. We expect to get it to about 0.9 seconds per sample in subsequent releases.
