The text discusses the launch of Lambda Reserved Cloud Clusters, which are designed for machine learning teams that require large compute power to train transformer models and other large datasets. The clusters are made up of 8x NVIDIA A100 bare metal GPUs connected with 1600 Gbps RDMA networking, offering faster node-to-node bandwidth than AWS's equivalent EC2 offering. This allows for multi-node distributed training, which is essential for creating large transformer or diffusion models. Voltron Data, a data company developing standard solutions for the Apache Arrow ecosystem, has partnered with Lambda to use these clusters for their needs. The clusters offer several benefits, including 25-57% savings on compute costs and 90% savings on egress fees compared to AWS. They also have flexible contract lengths starting at 6 months, dedicated GPUs, and fast networking speeds of 1600 Gbps. Additionally, Lambda provides pre-configured cloud products designed for deep learning, with support options available for premium customers.
