access gpt-3 with r in r

To access GPT-3 with R, you can use the HTTP API provided by OpenAI.

Here's a step-by-step guide:

1. First, you need to sign up for OpenAI's GPT-3 API on their website and obtain an API key.

2. Install the httr package in R, which provides tools for working with web APIs. You can install it using the following command:

main.r
install.packages("httr")
25 chars
2 lines

3. Next, you can make an HTTP request to the GPT-3 API endpoint using httr's POST() function. Here's an example:

main.r
library(httr)

req_body <- list(
  prompt = "Hello, GPT-3!",
  max_tokens = 10,
  temperature = 0.7
)

resp <- POST(
  url = "https://api.openai.com/v1/engines/davinci-codex/completions",
  body = req_body,
  add_headers("Authorization" = paste("Bearer", "<your_api_key>", sep=" "))
)

content(resp)
300 chars
16 lines

Note that you need to replace <your_api_key> with your actual API key.

4. Finally, you can extract the response from the API and use it in your R code. The response is in JSON format, so you may want to parse it using the jsonlite package. Here's an example:

main.r
library(jsonlite)

resp_content <- content(resp, as = "text")
resp_json <- fromJSON(resp_content)
generated_text <- resp_json$choices[[1]]$text
print(generated_text)
166 chars
7 lines

This will print the generated text returned by the GPT-3 API. You can customize the request by changing the prompt, max_tokens, temperature, and other parameters.
