## AI overview

This article introduces Sheaf, a serving framework for non-text foundation models. It argues that vLLM's serving optimizations benefit from the shared compute pattern of autoregressive text LLMs, while time-series, tabular, molecular, biological, and diffusion models require different batching, memory-management, and inference approaches. The article describes Sheaf's proposed capabilities, including typed contracts, model-aware batching, streaming, caching, observability, offline batch inference, asynchronous workers, LoRA adapter multiplexing, a typed Python client, Docker and KubeRay deployment support, and 27 PyPI backends.

## Source excerpt

vLLM solved inference for text LLMs. The same gap exists for every other class of foundation model -- time series, tabular, molecular, diffusion, and more. Sheaf fills it: typed contracts, model-type-aware batching, streaming, caching, observability, offline batch inference, an async-job worker, LoRA adapter multiplexing, a typed Python client, a Docker base image with KubeRay deployment, and 27 backends on PyPI.
