How they use AI
Anyscale builds the compute layer AI teams run on. Ray schedules work across CPUs and GPUs from a laptop to large clusters, and its libraries Ray Data, Ray Train and Ray Serve cover data preparation, distributed training and model serving. Teams use it to run LLM inference with engines such as vLLM and SGLang, and post-training and reinforcement learning with frameworks like SkyRL and veRL. The Anyscale Platform adds managed clusters, governance and multi-team controls on top of Ray.
