Pre-release

This release is a pre-release and may not be stable for production use.

🚀 What is inference-models?

inference-models is the library to make predictions from computer vision models provided by Roboflow — designed to be fast, reliable, and user-friendly. It offers:

  • Multi-Backend Support: Run models with PyTorch, ONNX, TensorRT, or Hugging Face backends
  • Automatic Model Loading: Smart model resolution and backend selection
  • Minimal Dependencies: Composable extras system for installing only what you need
  • Behavior-Based Interfaces: Models with similar behavior share consistent APIs; custom models can define their own
  • Full Roboflow Platform Support: Run any model trained on Roboflow

Visit our documentation for more information.

🛣️ Roadmap

With release 0.19.0, we have reached the first stable release of inference-models and fully integrated the package to inference - our main inference package, making it selectable backend for running predictions from models.

We are still making changes to add new features and models. API should be fairly stable already, but the problems may still occur. If you encounter any issues, please report them.

💻 Installation

CPU installation:

uv pip install inference-models
# or with pip
pip install inference-models

inference-models can be installed with CUDA and TensorRT support - see Installation Guide for more options.

🏃‍➡️ Usage

Pretrained Models

Load and run a pretrained model:

import cv2
import supervision as sv
from inference_models import AutoModel

# Load pretrained model from Roboflow
model = AutoModel.from_pretrained("rfdetr-base")

# Run inference (works with numpy arrays or torch.Tensor)
image = cv2.imread("<path-to-your-image>")
predictions = model(image)

# Use with supervision
annotator = sv.BoxAnnotator()
annotated = annotator.annotate(image, predictions[0].to_supervision())

Your Roboflow Models

Load and run models trained on the Roboflow platform:

import cv2
import supervision as sv
from inference_models import AutoModel

# Load your custom model from Roboflow
model = AutoModel.from_pretrained(
    "<your-project>/<version>",
    api_key="<your-api-key>"  # model access secured with API key
)

# Run inference (works with numpy arrays or torch.Tensor)
image = cv2.imread("<path-to-your-image>")
predictions = model(image)

# Use with supervision
annotator = sv.BoxAnnotator()
annotated = annotator.annotate(image, predictions[0].to_supervision())

🧠 Supported Model Architectures

  • RFDetr
  • SAM models family
  • Vision-Language Models (Florence, PaliGemma, Qwen, SmolVLM, Moondream)
  • OCR (DocTR, EasyOCR, TrOCR)
  • YOLO
  • and many more

For detailed model documentation, see Supported Models.

🔧 Run your local models

Load your own model implementations from a local directory - models with architectures not in the main inference-models package. This is especially valuable for production deployment of custom models.

from inference_models import AutoModel

model = AutoModel.from_pretrained(
    "/path/to/my_custom_model",
    allow_local_code_packages=True
)

See Load Models from Local Packages for complete details on creating custom model packages.

📄 License

The inference-models package is licensed under Apache 2.0. Individual models may have different licenses - see the Supported Models for details.
