#Rust 🦀 – Using #OpenAI Text Completion APIs from Rust

El Bruno - Feb 22 '23 - - Dev Community

Hi!

Let’s look at my sample repository on how to use OpenAI APIs in Rust. It includes a sample console app that uses the Text Completion API endpoint. In case you want to know more:

The completions endpoint can be used for a wide variety of tasks. It provides a simple but powerful interface to any of our models. You input some text as a prompt, and the model will generate a text completion that attempts to match whatever context or pattern you gave it. For example, if you give the API the prompt, “As Descartes said, I think, therefore”, it will return the completion” I am” with high probability.

Open AI API – Text Completion

The

  • As I mentioned in my previous post, I used a set of Structs to parse the JSON response from the API.
  • There are 2 ways to send the request JSON body, using a simple string or a HashMap to create the JSON.
  • I use a specific match to validate the following HTTP Codes
    • OK, parse the JSON response and show the completion text.
    • UNAUTHORIZED, this may usually trigger the use of an invalid API Key.
    • TOO_MANY_REQUESTS, also triggered when the team (or app) is overusing the current licence.

This is a sample response from the current Completions Rust Sample:
