The long awaited Llama 2 models are finally here! We are excited to show you how to use them with DeepInfra. These collection of models represent the state of the art in open source language models. They are made available by Meta AI and the license allows you to use them for commercial purposes. So now is the time to build your next AI application with Llama 2 hosted by DeepInfra, and save a ton of money compared to OpenAI's API.

Picking the right model

There are 3 different sizes of Llama 2 models as well as chat variants of each size:

Depending on the application you are building, you might want to use a different model. Smaller models are faster and cheaper to run, per token generated. Larger models take longer to run and cost more per token generated, but they are more accurate.

Getting started

Simply create an account on DeepInfra and get yourself an API Key.

# set the API key as an environment variable

Each model has a detailed API documentation page that will guide you through the process of using it. For example, here is the API documentation for the llama-2-7b-chat model.

Running inference

Making an inference request is as easy as making a POST request to our API.

curl -X POST \
    -d '{"input": "Who is Bill Clinton?"}'  \
    -H "Authorization: bearer $AUTH_TOKEN"  \
    -H 'Content-Type: application/json'  \

And you will get output like this:

   "inference_status" : {
      "cost" : 0.00454849982634187,
      "runtime_ms" : 9097,
      "status" : "succeeded"
   "request_id" : "RKQsJyO5n7ZLif------",
   "results" : [
         "generated_text" : "Who is Bill Clinton?\n\nAnswer: Bill Clinton is an American politician who served as the 42nd President of the United States from 1993 to 2001.
