chattr_use: Sets the LLM model to use in your session

In chattr: Interact with Large Language Models in 'RStudio'

Sets the LLM model to use in your session

Description

Sets the LLM model to use in your session

Usage

chattr_use(x = NULL, ...)

Arguments

x	A pre-determined provider/model name, an ellmer Chat object, or the path to a YAML file that contains a valid chattr model specification. The value 'test' is also acceptable, but it is meant for package examples, and internal testing. See 'Details' for more information.
...	Default values to modify.

Details

The valid pre-determined provider/models values are: 'databricks-dbrx', 'databricks-meta-llama31-70b', 'databricks-mixtral8x7b', 'gpt41-mini', 'gpt41-nano', 'gpt41', 'gpt4o', and 'ollama'.

If you need a provider, or model, not available as a pre-determined value, create an ellmer chat object and pass that to chattr_use(). The list of valid models are found here: https://ellmer.tidyverse.org/index.html#providers

Set a default

You can setup an R option to designate a default provider/model connection. To do this, pass an ellmer connection command you wish to use in the .chattr_chat option, for example: options(.chattr_chat = ellmer::chat_anthropic()). If you add that code to your .Rprofile, chattr will use that as the default model and settings to use every time you start an R session. Use the usethis::edit_r_profile() command to easily edit your .Rprofile.

Value

It returns console messages to allow the user select the model to use.

Examples

## Not run: 

# Use a valid provider/model label
chattr_use("gpt41-mini")

# Pass an `ellmer` object
my_chat <- ellmer::chat_anthropic()
chattr_use(my_chat)

## End(Not run)
