Palimpzest: Optimizing AI-Powered Analytics with Declarative Query Processing
Summary: PALIMPZEST: declarative language + system to express AI-powered analytics over unstructured corpora, automating orchestration of models, prompts, and data operations. A cost-based optimizer searches model/prompt/implementation choices to trade latency, cost, and accuracy, yielding up to 3.3x speedup and 2.9x cost reduction with improved F1.
