Falcon-7b

Falcon is a state of the art model used for text-generation. Follow the instructions given in this template to import it in Inferless.

---

Prerequisites

• Git. You would need git installed on your system if you wish to customize the repo after forking.
• Python>=3.8. You would need Python to customize the code in the app.py according to your needs.
• Curl. You would need Curl if you want to make API calls from the terminal itself.

Quick Start

Here is a quick start to help you get up and running with Falcon 7b on Inferless.

Fork the Repository

Get started by forking the repository. You can do this by clicking on the fork button in the top right corner of the repository page.

This will create a copy of the repository in your own GitHub account, allowing you to make changes and customize it according to your needs.

Create a Custom Runtime in Inferless

To access the custom runtime window in Inferless, simply navigate to the sidebar and click on the Create new Runtime button. A convenient pop-up will appear.

Next, provide a suitable name for your custom runtime and proceed by uploading the falcon-7b.yaml file mentioned above. Finally, ensure you save your changes by clicking on the designated save button.

Import the Model in Inferless

Log in to your inferless account, select the workspace you want the model to be imported into and click the Add Model button.

Select the PyTorch as framework and choose Repo(custom code) as your model source and use the forked repo URL as the Model URL.

After the create model step, while setting the configuration for the model make sure to select the appropriate runtime.

Enter all the required details to Import your model. Refer this link for more information on model import.

The following is a sample Input and Output JSON for this model which you can use while importing this model on Inferless.

Input

{
  "inputs": [
    {
      "data": [
        "Once upon a time"
      ],
      "name": "prompt",
      "shape": [
        1
      ],
      "datatype": "BYTES"
    }
  ]
}

Output

{
  "outputs": [
    {
      "data": [
        "Once upon a time the sun was up he would look down to the valley below and wonder wis"
      ],
      "name": "generated_text",
      "shape": [
        1
      ],
      "datatype": "BYTES"
    }
  ]
}

Curl Command

Following is an example of the curl command you can use to make inference. You can find the exact curl command in the Model's API page in Inferless.

curl --location '<your_inference_url>' \
          --header 'Content-Type: application/json' \
          --header 'Authorization: Bearer <your_api_key>' \
          --data '{
                    "inputs": [
                        {
                            "data": [
                                "Enter the content here..."
                            ],
                            "name": "prompt",
                            "shape": [
                                1
                            ],
                            "datatype": "BYTES"
                        }
                    ]
                }'

Customizing the Code

Open the app.py file. This contains the main code for inference. It has three main functions, initialize, infer and finalize.

Initialize - This function is executed during the cold start and is used to initialize the model. If you have any custom configurations or settings that need to be applied during the initialization, make sure to add them in this function.

Infer - This function is where the inference happens. The argument to this function inputs, is a dictionary containing all the input parameters. The keys are the same as the name given in inputs. Refer to input for more.

def infer(self, inputs):
    prompt = inputs["prompt"]

Finalize - This function is used to perform any cleanup activity for example you can unload the model from the gpu by setting self.pipe = None.

For more information refer to the Inferless docs.
