Amazon SageMaker has released the Training Sessions API, enabling users to implement custom large-model training workflows—such as SFT, RLHF, GRPO, and KTO—using pure Python scripts. GPU resource scheduling, fault tolerance, distributed execution, and checkpoint management are all handled by the service.
SF Compute was founded by Evan Conrad and is dedicated to building a neutral, programmable GPU computing‑power trading infrastructure that supports physical delivery. Its model rejects the abstraction of FLOPS as a commodity, emphasizing hardware heterogeneity, actual delivery, and real‑time constraints—such as interrupt tolerance, InfiniBand topology, and firmware versions. The platform has already facilitated tens of billions of dollars in transaction volume and introduced low‑level capabilities like dynamic InfiniBand subnet partitioning.
SF Compute was founded by Evan Conrad and focuses on enabling programmable, physically settled trading of GPU computing power. It does not operate its own data centers; instead, it leverages full-stack technology to collaborate with third-party facilities in co-building a “sovereign compute cloud,” emphasizing market neutrality and infrastructure controllability. The company has already facilitated hundreds of millions of dollars in transaction volume and implemented key capabilities such as dynamic InfiniBand partitioning.
