BentoML is a Python framework for building and serving AI applications, designed to simplify the creation of REST APIs for any machine learning model. It targets AI/ML engineers and developers who need to deploy models efficiently, offering features like automatic Docker containerization, dependency management, and optimized inference serving.

How It Works

BentoML abstracts the complexities of model serving by allowing users to define inference logic within Python classes and functions, decorated with @bentoml.service and @bentoml.api. It automatically handles dependency packaging, environment replication, and API server generation. Key optimizations include dynamic batching, model parallelism, and multi-model orchestration, aiming to maximize hardware utilization for high-performance inference.

Quick Start & Requirements

• Install: pip install -U bentoml
• Prerequisites: Python ≥3.9. Additional dependencies (e.g., torch, transformers) are specified per service.
• Local Run: bentoml serve
• Docker Deployment: bentoml build then bentoml containerize and docker run.
• Documentation: https://docs.bentoml.org/en/latest/
• Examples: https://github.com/bentoml/BentoML/tree/main/examples
