RunPod Stable Diffusion, Serverless Complete Tutorial, June 2023 (Updated)

How to Create a Stable Diffusion API Using RunPod Serverless

1. Prerequisites:

   • Ensure you have Docker and Git installed on your system.
   • Obtain custom models from civitai.com.
   • Install Postman for testing your endpoint.

2. Download Template from GitHub:

   • Clone the GitHub repository for the template provided in the helper file.
   • Download custom models (e.g., one for photorealistic images and another for anime images) and place them in the worker template directory.
   • Name the models as model.tensor_safe and model2.tensor_safe.

3. Modify Handler Method:

   • The Handler method defines the entry point for calling the run interference function to support stable diffusion APIs.
   • Customize the Handler method as needed.

4. Build Docker Image:

   • Use docker build and docker tag commands to build and tag the Docker image.
   • Push the Docker image to a container registry using the docker push command.

5. Create Serverless Endpoint:

   • Use RunPod to create a serverless endpoint.
   • Create a template referencing the Docker image pushed to Docker Hub.
   • Set configurations such as disk size, number of workers, idle timeout, and Q delay.

6. Generate API Key:

   • Note the ID of the serverless endpoint created.
   • Create an API key in the settings section of RunPod and securely store it.

7. Set Up Postman:

   • Import the Postman configuration file provided in the helper file.
   • Paste your serverless endpoint ID and API key in the variables tab.

8. Run Jobs Using Postman:

   • The Postman Collection includes requests for running jobs asynchronously or synchronously and checking job status.
   • Execute requests based on the desired stable diffusion API.

9. Visualize Images:

   • Use the provided script in Postman to visualize images generated by the stable diffusion API.

10. Explore Different Models:

    • Change the API name in the request to get models to see available models.
    • Select a model and make an image-to-image request.

11. Check Stable Diffusion Options:

    • Change the API name to get options to view available options for the stable diffusion API.

12. Wrap-Up:

    • Experiment with different APIs and options to explore the capabilities of the stable diffusion API.
    • Provide feedback and suggestions for future tutorials to help improve content quality.

By following these steps, you can create and test your own stable diffusion API using RunPod Serverless efficiently.
