AI Tools

gptstudio in RStudio

Chat and coding functions integrated into RStudio

1. Setup .Renviron file:

require(usethis)
edit_r_environ()

Add your API key, and set OPEN_AI_API_URL to CBorg

OPENAI_API_KEY="sk-..."
OPENAI_API_URL="https://api.cborg.lbl.gov/v1"

2. Install the Development Version of gptstudio

As of Jun 12th, 2025 the default version of gptstudio does not support OpenAI-compatible servers (i.e., the CBorg API Server). The development version of gptstudio is required.

Remove the default version, if already installed:

remove.packages("gptstudio")

Install development version using pak:

install.packages("pak")
pak::pak("MichelNivard/gptstudio")

3. Start gptstudio Chat

Note: the port number of the shiny background process (shown as 3442 below) will change on each startup - so, this line of code cannot be hard coded in a file - you must click on the link in RStudio console when starting up the Chat.

gptstudio::gptstudio_chat()
rstudioapi::viewer("http://127.0.0.1:3442")

You can then configure the models in the Chat UI by clicking the “>” button in the top left corner of that Viewer pane.

Recommended model: openai/gpt-4.1

Troubleshooting

Make sure that the promises package is at least version 1.3.3
