%description
Offers an interactive 'RStudio' gadget interface for communicating with
'OpenAI' large language models (e.g., 'gpt-4o', 'gpt-4o-mini', 'gpt-4.1',
'o1', 'o3-mini') (<https://platform.openai.com/docs/api-reference>).
Enables users to conduct multiple chat conversations simultaneously in
separate tabs. Supports uploading local files (R, PDF, DOCX) to provide
context for the models. Allows per-conversation configuration of model
parameters such as temperature and system messages (where supported by the
model). API interactions via the 'httr' package are performed
asynchronously using 'promises' and 'future' to avoid blocking the R
console. Useful for tasks like code generation, text summarization, and
document analysis directly within the 'RStudio' environment. Requires an
'OpenAI' API key set as an environment variable.
