RiftStack's Emmy Compiler Generates CUDA Kernels That Beat Hand-Tuned Libraries on NVIDIA RTX 5090
Benchmark results for Emmy, RiftStack's AI-driven ML compiler. On Gemma 4 12B, Emmy-generated CUDA kernels reached up to 1.6x the throughput of NVIDIA's cuBLASLt on the RTX 5090, with a 1.30x geometric-mean speedup over PyTorch eager across all 277 deployed kernel shapes.

RiftStack Releases Emmy, an Open-Source ML Compiler That Lowers PyTorch Graphs to CUDA in 5,000 Lines of Python
Emmy, the ML compiler behind RiftStack's inference work, is available as open source under Apache-2.0. It lowers PyTorch graphs to CUDA through six inspectable intermediate representations and picks kernel schedules by search rather than fixed heuristics.

CloudRift in the press
In 2025 the hardware press picked up a virtualization reset bug we hit on the NVIDIA RTX 5090 and RTX PRO 6000, and the $1,000 bounty we posted for a fix.
