Pretrained Model Aliases

Built-in COCO-pretrained model aliases you can run with Roboflow Inference without training a model.

Roboflow Inference ships with a set of pretrained models trained on the COCO dataset and exposed under short aliases such as rfdetr-small or yolov8n-640.

Aliases are convenience shortcuts: you do not need to know the underlying Roboflow project and version, and you can pass the alias anywhere a model ID is accepted.

Code sample

SDK (Python)

1

Get your API Key

Create a Roboflow account, find your key on the Roboflow API settings page and make it available to your shell:

export ROBOFLOW_API_KEY="your-key-here"

2

Install the dependencies

pip install inference-sdk

3

Run the model

Pass the alias as model_id:

import os
from inference_sdk import InferenceHTTPClient

client = InferenceHTTPClient(
    api_url="https://serverless.roboflow.com",
    api_key=os.environ["ROBOFLOW_API_KEY"],
)

results = client.infer(
    "https://media.roboflow.com/inference/people-walking.jpg",
    model_id="rfdetr-small",
)
print(results["predictions"])

Inference (native)

1

Install the dependencies

Install the Inference package to load weights into your own process:

pip install inference

2

Run the model

from inference import get_model

model = get_model(model_id="rfdetr-small")

results = model.infer("https://media.roboflow.com/inference/people-walking.jpg")
print(results[0].predictions)

Set api_url to match your deployment target:

• https://serverless.roboflow.com for the Serverless Cloud API.

• http://localhost:9001 for a local Inference server.

• Your Dedicated Deployment URL for a private endpoint.
