- **Inference Optimization**: Boost deep learning performance in computer vision, automatic speech recognition, generative AI, natural language processing with large and small language models, and many other common tasks.

- **Flexible Model Support**: Use models trained with popular frameworks such as PyTorch, TensorFlow, ONNX, Keras, PaddlePaddle, and JAX/Flax. Directly integrate models built with transformers and diffusers from the Hugging Face Hub using Optimum Intel. Convert and deploy models without original frameworks.

- **Broad Platform Compatibility**: Reduce resource demands and efficiently deploy on a range of platforms from edge to cloud. OpenVINO™ supports inference on CPU (x86, ARM), GPU (OpenCL capable, integrated and discrete) and AI accelerators (Intel NPU).

- **Community and Ecosystem**: Join an active community contributing to the enhancement of deep learning performance across various domains.

Here are easy-to-follow code examples demonstrating how to run PyTorch and TensorFlow model inference using OpenVINO:



**PyTorch Model**



```python

import openvino as ov

import torch

import torchvision



# load PyTorch model into memory

model = torch.hub.load("pytorch/vision", "shufflenet_v2_x1_0", weights="DEFAULT")



# convert the model into OpenVINO model

example = torch.randn(1, 3, 224, 224)

ov_model = ov.convert_model(model, example_input=(example,))



# compile the model for CPU device

core = ov.Core()

compiled_model = core.compile_model(ov_model, 'CPU')



# infer the model on random data

output = compiled_model({0: example.numpy()})

```



**TensorFlow Model**



```python

import numpy as np

import openvino as ov

import tensorflow as tf



# load TensorFlow model into memory

model = tf.keras.applications.MobileNetV2(weights='imagenet')



# convert the model into OpenVINO model

ov_model = ov.convert_model(model)



# compile the model for CPU device

core = ov.Core()

compiled_model = core.compile_model(ov_model, 'CPU')



# infer the model on random data

data = np.random.rand(1, 224, 224, 3)

output = compiled_model({0: data})

```



OpenVINO supports the CPU, GPU, and NPU [devices](https://docs.openvino.ai/2025/openvino-workflow/running-inference/inference-devices-and-modes.html) and works with models from PyTorch, TensorFlow, ONNX, TensorFlow Lite, PaddlePaddle, and JAX/Flax [frameworks](https://docs.openvino.ai/2025/openvino-workflow/model-preparation.html). It includes [APIs](https://docs.openvino.ai/2025/api/api_reference.html) in C++, Python, C, NodeJS, and offers the GenAI API for optimized model pipelines and performance.



## Generative AI with OpenVINO



Get started with the OpenVINO GenAI [installation](https://docs.openvino.ai/2025/get-started/install-openvino/install-openvino-genai.html) and refer to the [detailed guide](https://docs.openvino.ai/2025/openvino-workflow-generative/generative-inference.html) to explore the capabilities of Generative AI using OpenVINO.



Learn how to run LLMs and GenAI with [Samples](https://github.com/openvinotoolkit/openvino.genai/tree/master/samples) in the [OpenVINO™ GenAI repo](https://github.com/openvinotoolkit/openvino.genai).
