Sponsored Session: Lightning Talk: PyTorch and Democratization of AI Accelerators
summary
Rebellions describes native PyTorch integration via a 2024-launched torch-rlbn package that targets a chimnet-based flagship chip claiming 32x compute over prior silicon and performance comparable to H200. The stack uses PyTorch dispatch and graph/eager paths, Triton and vLLM for model serving, a custom collective-communication backend for model parallelism, and a Kubernetes-ready deployment slated for H1 2026, plus Out-of-Tree support to plug into existing workflows.
