Usage example

Client sends post request with the params prompts (String) and optional params to http://127.0.0.1:5005/api/v1/predict

POST /api/v1/predict
{
  prompt: "What is the meaning of life?",
  moderation: true,
  max_tokens: 128, 
  temperature: 0.4
}

and the server responds with the predicted result:

{
    "result": {
        "result": "The meaning of life is to find fulfillment and purpose through living a life of value and making a positive contribution to the world.",
        "temperature": 0.4,
