So, a new computer vision model just dropped last night. It's called GPT-54o-mini-vision-pro-max-xxxl. It's a super cool model, open-source, open-weights, open-data, all the good stuff.
You're excited. You want to try it out.
But it's written in a new framework, TyPorch, that you know nothing about.
You don't want to spend a weekend learning TyPorch just to find out the model is not what you expected.
This is where x.infer comes in. It's a simple library that allows you to run inference with any computer vision model in just a few lines of code. All in Python.
Out of the box, x.infer supports the following frameworks:
In total x.infer already supports over 1000+ models from all the above frameworks.
Tasks supported:
Run any supported model using the following 4 lines of code:
import xinfer
model = xinfer.create_model("vikhyatk/moondream2")
model.infer(image, prompt) # Run single inference
model.infer_batch(images, prompts) # Run batch inference
model.launch_gradio() # Launch Gradio interfaceHave a custom model? Create a class that implements the BaseModel interface and register it with x.infer. See Adding New Models for more details.
- Unified Interface: Interact with different machine learning models through a single, consistent API.
- Modular Design: Integrate and swap out models without altering the core framework.
- Extensibility: Add support for new models and libraries with minimal code changes.
Here's a quick example demonstrating how to use x.infer with a Transformers model:
import xinfer
model = xinfer.create_model("vikhyatk/moondream2")
image = "https://raw.githubusercontent.com/vikhyat/moondream/main/assets/demo-1.jpg"
prompt = "Describe this image. "
model.infer(image, prompt)

For all models, you can launch a Gradio interface to interact with the model.
model.launch_gradio()You can also launch a Gradio interface with all models available in a dropdown. Pick a model, upload an image, and see the inference results.
xinfer.launch_gradio_demo()See Gradio Demo for more details.
Important
You must have PyTorch installed to use x.infer.
To install the barebones x.infer (without any optional dependencies), run:
pip install xinferx.infer can be used with multiple optional libraries. You'll just need to install one or more of the following:
pip install "xinfer[transformers]"
pip install "xinfer[ultralytics]"
pip install "xinfer[timm]"
pip install "xinfer[vllm]"To install all libraries, run:
pip install "xinfer[all]"To install from a local directory, run:
git clone https://github.com/dnth/x.infer.git
cd x.infer
pip install -e .| Model | Usage |
|---|---|
| BLIP2 Series | xinfer.create_model("Salesforce/blip2-opt-2.7b") |
| Moondream2 | xinfer.create_model("vikhyatk/moondream2") |
| VLRM-BLIP2 | xinfer.create_model("sashakunitsyn/vlrm-blip2-opt-2.7b") |
| JoyCaption | xinfer.create_model("fancyfeast/llama-joycaption-alpha-two-hf-llava") |
You can also load any AutoModelForVision2Seq model
from Transformers by using the Vision2SeqModel class.
from xinfer.transformers import Vision2SeqModel
model = Vision2SeqModel("facebook/chameleon-7b")
model = xinfer.create_model(model)All models from TIMM fine-tuned for ImageNet 1k are supported.
For example load a resnet18.a1_in1k model:
xinfer.create_model("resnet18.a1_in1k")You can also load any model (or a custom timm model) by using the TIMMModel class.
from xinfer.timm import TimmModel
model = TimmModel("resnet18")
model = xinfer.create_model(model)| Model | Usage |
|---|---|
| YOLOv8 Series | xinfer.create_model("yolov8n") |
| YOLOv10 Series | xinfer.create_model("yolov10x") |
| YOLOv11 Series | xinfer.create_model("yolov11s") |
You can also load any model from Ultralytics by using the UltralyticsModel class.
from xinfer.ultralytics import UltralyticsModel
model = UltralyticsModel("yolov5n6u")
model = xinfer.create_model(model)| Model | Usage |
|---|---|
| Molmo-72B | xinfer.create_model("allenai/Molmo-72B-0924") |
| Molmo-7B-D | xinfer.create_model("allenai/Molmo-7B-D-0924") |
| Molmo-7B-O | xinfer.create_model("allenai/Molmo-7B-O-0924") |

| LLaVA Phi3 | xinfer.create_model("ollama/llava-phi3") |
-
Step 1: Create a new model class that implements the
BaseModelinterface. -
Step 2: Implement the required abstract methods
load_model,infer, andinfer_batch. -
Step 3: Decorate your class with the
register_modeldecorator, specifying the model ID, implementation, and input/output.
For example:
@register_model("my-model", "custom", ModelInputOutput.IMAGE_TEXT_TO_TEXT)
class MyModel(BaseModel):
def load_model(self):
# Load your model here
pass
def infer(self, image, prompt):
# Run single inference
pass
def infer_batch(self, images, prompts):
# Run batch inference here
passSee an example implementation of the Molmo model here.
