Highlights

🍱 Bento is the container for AI apps

• Open standard and SDK for AI apps, pack your code, inference pipelines, model files, dependencies, and runtime configurations in a Bento.
• Auto-generate API servers, supporting REST API, gRPC, and long-running inference jobs.
• Auto-generate Docker container images.

🏄 Freedom to build with any AI models

• Import from any model hub or bring your own models built with frameworks like PyTorch, TensorFlow, Keras, Scikit-Learn, XGBoost and many more.
• Native support for LLM inference, generative AI, embedding creation, and multi-modal AI apps.
• Run and debug your BentoML apps locally on Mac, Windows, or Linux.

🍭 Simplify modern AI application architecture

• Python-first! Effortlessly scale complex AI workloads.
• Enable GPU inference without the headache.
• Compose multiple models to run concurrently or sequentially, over multiple GPUs or on a Kubernetes Cluster.
• Natively integrates with MLFlow, LangChain, Kubeflow, Triton, Spark, Ray, and many more to complete your production AI stack.

🚀 Deploy Anywhere

• One-click deployment to ☁️ BentoCloud, the Serverless platform made for hosting and operating AI apps.
• Scalable BentoML deployment with 🦄️ Yatai on Kubernetes.
• Deploy auto-generated container images anywhere docker runs.

🛠️ What you can build with BentoML

• OpenLLM - An open platform for operating large language models (LLMs) in production.
• StableDiffusion - Create your own text-to-image service with any diffusion models.
• CLIP-API-service - Embed images and sentences, object recognition, visual reasoning, image classification, and reverse image search.
• Transformer NLP Service - Online inference API for Transformer NLP models.
• Distributed TaskMatrix(Visual ChatGPT) - Scalable deployment for TaskMatrix from Microsoft.
• Fraud Detection - Online model serving with custom XGBoost model.
• OCR as a Service - Turn any OCR models into online inference API endpoints.
• Replace Anything - Combine the power of Segment Anything and Stable Diffusion.
• DeepFloyd IF Multi-GPU serving - Serve IF models easily across multiple GPUs.
• Sentence Embedding as a Service - Start a high-performance REST API server for generating text embeddings with one command.

Getting Started

Save or import models in BentoML local model store:

import bentoml
import transformers

pipe = transformers.pipeline("text-classification")

bentoml.transformers.save_model(
  "text-classification-pipe",
  pipe,
  signatures={
    "__call__": {"batchable": True}  # Enable dynamic batching for model
  }
)

View all models saved locally:

$ bentoml models list

Tag                                     Module                Size        Creation Time
text-classification-pipe:kn6mr3aubcuf…  bentoml.transformers  256.35 MiB  2023-05-17 14:36:25

Define how your model runs in a service.py file:

import bentoml

model_runner = bentoml.models.get("text-classification-pipe").to_runner()

svc = bentoml.Service("text-classification-service", runners=[model_runner])

@svc.api(input=bentoml.io.Text(), output=bentoml.io.JSON())
async def classify(text: str) -> str:
    results = await model_runner.async_run([text])
    return results[0]

Now, run the API service locally:

bentoml serve service.py:svc

Sent a prediction request:

$ curl -X POST -H "Content-Type: text/plain" --data "BentoML is awesome" http://localhost:3000/classify

{"label":"POSITIVE","score":0.9129443168640137}%

Define how a Bento can be built for deployment, with bentofile.yaml:

service: 'service.py:svc'
name: text-classification-svc
include:
  - 'service.py'
python:
  packages:
  - torch>=2.0
  - transformers

Build a Bento and generate a docker image:

$ bentoml build
...
Successfully built Bento(tag="text-classification-svc:mc322vaubkuapuqj").

$ bentoml containerize text-classification-svc
Building OCI-compliant image for text-classification-svc:mc322vaubkuapuqj with docker
...
Successfully built Bento container for "text-classification-svc" with tag(s) "text-classification-svc:mc322vaubkuapuqj"

$ docker run -p 3000:3000 text-classification-svc:mc322vaubkuapuqj

Usage Reporting

BentoML collects usage data that helps our team to improve the product. Only BentoML's internal API calls are being reported. We strip out as much potentially sensitive information as possible, and we will never collect user code, model data, model names, or stack traces. Here's the code for usage tracking. You can opt-out of usage tracking by the --do-not-track CLI option:

bentoml [command] --do-not-track

Or by setting environment variable BENTOML_DO_NOT_TRACK=True:

export BENTOML_DO_NOT_TRACK=True
