Introduction Foundation models—large, pre‑trained neural networks that can be adapted to a wide range of downstream tasks—have exploded in popularity across vision, language, audio, and multimodal domains. Their sheer size (often hundreds of billions of parameters) and the need to process heterogeneous inputs (e.g., text + image + audio) make low‑latency inference a formidable engineering challenge. Enter heterogeneous inference clusters: collections of compute nodes that differ in CPU, GPU, accelerator, memory, and networking capabilities. By intelligently orchestrating these diverse resources, organizations can meet strict Service Level Objectives (SLOs) while controlling cost. ...

Introduction Enterprises are increasingly demanding intelligent workloads that can prove their correctness, protect data privacy, and scale across heterogeneous environments. Traditional monolithic AI services struggle to satisfy these constraints because they rely on centralized data silos, opaque model pipelines, and static provisioning. A new class of systems—autonomous agent orchestration frameworks—is emerging to address this gap. By treating each AI component as a self‑contained, verifiable agent and coordinating them through a flexible orchestration layer, organizations can: ...

Most RAG pipelines rely on vector search: documents are embedded into a high‑dimensional space, an approximate nearest‑neighbor (ANN) index is built, and the model retrieves the top‑k most similar chunks at inference time. ...

The benefits are clear: reduced latency, privacy preservation, and resilience to network outages. ...
