Abacus: A Cost-Based Optimizer for Semantic Operator Systems
Summary: Abacus: cost-based optimizer for semantic-operator pipelines over unstructured docs, choosing physical implementations of LLM maps/filters/joins under quality–cost–latency objectives. Uses few validation examples / priors / LLM judge to estimate operator performance and globally optimize end-to-end systems.
