How to avoid word limit in ChatGPT in R? - r

Question

I registered at this link to get an API for ChatGPT.
And I used the chatgpt package in R.
library(chatgpt)
And set environment:
Sys.setenv(OPENAI_API_KEY = "sk-YOURAPI")
I used this function:
chatgpt::ask_chatgpt("How to make a strawberry pie to donate to my wife? Ingredients, please.")
Sometimes the output is missing words. For example:
*** ChatGPT input:
How to make a strawberry pie to donate to my wife? Ingredients, please.
[1] ... and your wife is"
It does not complete the text after is. Is there any solution for this on R?
Similar question on reddit.
EDIT
I tried increasing the processing time of the function (so that the chat would finish typing all the content, without stopping midway). Like this:
for (i in 35) {
print(chatgpt::ask_chatgpt("How to make a strawberry pie to donate to my wife? Ingredients, please."))
Sys.sleep(i)
}

Answer 1

What you are running into is prompt engineering. GPT is a sophisticated autocomplete engine.
If you are not getting the right response you need to recraft your prompt.
You can always test your prompts in the OpenAI playground:
https://platform.openai.com/playground
I was able to get a list of ingredients and cooking steps by using the following prompt:
How can I make a strawberry pie to donate to my wife? Please provide first a numbered list of ingredients, and secondly a numbered lists of steps.
Here is the output I got in the playground:
Ingredients:
1. 2 ½ cups of fresh or frozen strawberries
2. 1 9-inch pre-made pie crust
3. ¾ cup of granulated sugar
4. 2 tablespoons of cornstarch
5. ¼ teaspoon of salt
6. 1 tablespoon of fresh lemon juice
Steps:
1. Preheat oven to 425 degrees F.
2. Place the pre-made pie crust in a 9-inch pie dish and set aside.
3. In a medium bowl, combine the strawberries, sugar, cornstarch, salt, and lemon juice. Stir until the mixture is combined.
4. Pour the strawberry mixture into the pre-made pie crust.
5. Place the pie dish on a baking sheet and bake for 15 minutes.
6. Reduce the oven temperature to 375 degrees F and bake for an additional 25 minutes.
7. Allow the pie to cool completely before serving.
Another thing to note, per the Github repo for the chatgpt R library it says "The {chatgpt} R package provides a set of features to assist in R coding."

I would use the OpenAI APIs directly, this way you will have a lot more control over your response. I am not an R specialist, but this is how the OpenAI Playground showed me how to do it.
library(httr)
response <- GET("https://api.openai.com/v1/completions",
query = list(
prompt = "How can I make a strawberry pie to donate to my wife? Please provide first a numbered list of ingredients, and secondly a numbered lists of steps.",
max_tokens = 200,
model = 'text-davinci-003'
),
add_headers(Authorization = "bearer YOUR_OPENAI_API_KEY")
)
content(response)
Ref: OpenAI playground

Answer 2

Increase max_tokens to get longer answer.
