- **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 (Intel integrated & discrete GPU) and AI accelerators (Intel NPU).
- **Community and Ecosystem**: Join an active community contributing to the enhancement of deep learning performance across various domains.

Discover more examples in the [OpenVINO Samples (Python & C++)](https://docs.openvino.ai/2026/get-started/learn-openvino/openvino-samples.html) and [Notebooks (Python)](https://docs.openvino.ai/2026/get-started/learn-openvino/interactive-tutorials-python.html).

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/2026/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/2026/openvino-workflow/model-preparation.html). It includes [APIs](https://docs.openvino.ai/2026/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/2026/get-started/install-openvino/install-openvino-genai.html) and refer to the [detailed guide](https://docs.openvino.ai/2026/openvino-workflow-generative/generative-inference.html) to explore the capabilities of Generative AI using OpenVINO.
