chatdmdi

A minimal R wrapper for using ChatDMDI in RStudio, based on the ellmer package.

Installation

Install from GitHub:

install.packages("devtools")
devtools::install_github("Jacobzwj/chatdmdi")

Supported models

You can choose one of the following model names for the model parameter:

• gpt-4o-image-vip
• o1
• gpt-4.1
• gpt-4o
• gpt-4o-mini
• claude-3-7-sonnet-20250219
• claude-3-5-haiku-20241022
• grok-3
• grok-3-reason
• deepseek-r1
• deepseek-v3
• gemini-2.0-flash

Usage

library(chatdmdi)

# Choose the model name and API key
chatdmdi(
  model = "gpt-4o-mini",
  api_key ="sk-XXXXXXXXX", #your api_key from ChatDMDI website
)

By default the function starts a background process and opens the UI at http://127.0.0.1:8765. If you're in RStudio, it opens in the Viewer pane.

Session behavior

• restart viewer: close the Viewer and call chatdmdi() again with the same model to reopen the existing session and preserve messages.
• change model: change the model name and call chatdmdi() to start a new session with the new model; previous history is cleared.
