BentoML is a machine learning model serving framework and GPU-accelerated inference server designed to package, deploy, and scale AI models as production-ready REST APIs. It functions as an AI model lifecycle manager and an inference graph orchestrator, enabling the chaining of multiple models and custom logic into complex pipelines for advanced task sequences.
The framework distinguishes itself through a dynamic batching engine that optimizes GPU throughput and an artifact-based packaging system that bundles model weights and dependencies into immutable archives for consistent deployment. It provides an enterprise AI API gateway to route requests across different language model providers and manage resource quotas through a unified interface.
The system covers broad capabilities including MLOps lifecycle management with canary and shadow deployment strategies, distributed inference execution across multiple GPUs, and adaptive resource scaling. It also incorporates model health monitoring and uses Python type hints to automatically generate request and response schemas for its APIs.
