To generate text, send a POST request to the /api/v1/generate endpoint. The request body should be a JSON object with the following keys: prompt: The input prompt (required). min_length: The minimum length of the sequence to be generated (optional, default is 0). max_length: The maximum length of the sequence to be generated (optional, default is 50). top_p: The nucleus sampling probability (optional, default is 0.95). temperature: The temperature for sampling (optional, default is 0.6). For example, you can use curl to send a request

curl -k -s -X POST https://localhost:5000/api/v1/generate \
     -H "Content-Type: application/json" \
     -d '{"prompt": "Below is an instruction that describes a task. Write a response that appropriately completes the request\n### Instruction: write a for loop in typescript\n### Response:", "max_length": 1000, "temperature": 0.7}'
