This handler was implemented using the replicate library that is provided by Replicate.

The required arguments to establish a connection are,

  • model_name: Model name which you want to access in MindsDB. e.g ‘air-forever/kandinsky-2’
  • version: version hash/id which you want to use in MindsDB.
  • api_key: API key from Replicate Platform you can found here.

Before you can use Replicate, it’s essential to authenticate by setting your API token in an environment variable named REPLICATE_API_TOKEN. This token acts as a key to enable access to Replicate’s features.

  1. Using pip:

If you’re working in a standard Python environment (using pip for package management), set your token as an environment variable by running the following command in your terminal:

On Linux, Mac:

export REPLICATE_API_TOKEN='YOUR_TOKEN'

On Windows:

set REPLICATE_API_TOKEN=YOUR_TOKEN
  1. Using Docker:

For Docker users, the process slightly differs. You need to pass the environment variable directly to the Docker container when running it. Use this command:

docker run -e REPLICATE_API_TOKEN='YOUR_TOKEN' -p 47334:47334 -p 47335:47335 mindsdb/mindsdb

Again, replace ‘YOUR_TOKEN’ with your actual Replicate API token.

​
Usage

To use this handler and connect to a Replicate cluster in MindsDB, you need an account on Replicate. Make sure to create an account by following this link.

To establish the connection and create a model in MindsDB, use the following syntax:


CREATE MODEL aiforever
PREDICT url
USING
    engine = 'replicate',
    model_name= 'ai-forever/kandinsky-2',
    version ='2af375da21c5b824a84e1c459f45b69a117ec8649c2aa974112d7cf1840fc0ce',
    api_key = 'r8_BpO.........................';

You can use the DESCRIBE PREDICTOR query to see the available parameters that you can specify to customize your predictions:

DESCRIBE PREDICTOR mindsdb.aiforever.features;

+---------------------+-------------------+--------------------------------------------------------+---------+

Now, you can use the established connection to query your ML Model as follows:

SELECT *
FROM aiforever
WHERE prompt='Great warrior Arjun from Mahabharata, looking at camera,cinematic lighting, 4k quality';

Output

  • IMPORTANT NOTE: PREDICTED URL will only work for 24 hours after prediction.

Note: Replicate provides only a few free predictions, so choose your predictions wisely. Don’t let the machines have all the fun, save some for yourself! 😉
