Chat with AI in RStudio

chattr is a bundle that allows interplay with Giant Language Fashions (LLMs),
comparable to GitHub Copilot Chat, and OpenAI’s GPT 3.5 and 4. The primary car is a
Shiny app that runs contained in the RStudio IDE. Right here is an instance of what it seems
like operating contained in the Viewer pane:

Determine 1: chattr’s Shiny app

Though this text highlights chattr’s integration with the RStudio IDE,
it’s value mentioning that it really works exterior RStudio, for instance the terminal.

Getting began

To get began, set up the bundle from CRAN, after which name the Shiny app
utilizing the chattr_app() operate:

# Set up from CRAN
set up.packages("chattr")

# Run the app
chattr::chattr_app()

#> ── chattr - Out there fashions 
#> Choose the variety of the mannequin you want to use:
#>
#> 1: GitHub - Copilot Chat -  (copilot) 
#>
#> 2: OpenAI - Chat Completions - gpt-3.5-turbo (gpt35) 
#>
#> 3: OpenAI - Chat Completions - gpt-4 (gpt4) 
#>
#> 4: LlamaGPT - ~/ggml-gpt4all-j-v1.3-groovy.bin (llamagpt) 
#>
#>
#> Choice:
>

After you choose the mannequin you want to work together with, the app will open. The
following screenshot supplies an summary of the completely different buttons and
keyboard shortcuts you need to use with the app:

You can begin writing your requests in the primary textual content field on the prime left of the
app. Then submit your query by both clicking on the ‘Submit’ button, or
by urgent Shift+Enter.

chattr parses the output of the LLM, and shows the code inside chunks. It
additionally locations three buttons on the prime of every chunk. One to repeat the code to the
clipboard, the opposite to repeat it on to your energetic script in RStudio, and
one to repeat the code to a brand new script. To shut the app, press the ‘Escape’ key.

Urgent the ‘Settings’ button will open the defaults that the chat session
is utilizing. These might be modified as you see match. The ‘Immediate’ textual content field is
the extra textual content being despatched to the LLM as a part of your query.

Personalised setup

chattr will attempt to determine which fashions you might have setup,
and can embrace solely these within the choice menu. For Copilot and OpenAI,
chattr confirms that there’s an obtainable authentication token as a way to
show them within the menu. For instance, when you have solely have
OpenAI setup, then the immediate will look one thing like this:

chattr::chattr_app()
#> ── chattr - Out there fashions 
#> Choose the variety of the mannequin you want to use:
#>
#> 2: OpenAI - Chat Completions - gpt-3.5-turbo (gpt35) 
#>
#> 3: OpenAI - Chat Completions - gpt-4 (gpt4) 
#>
#> Choice:
>

If you happen to want to keep away from the menu, use the chattr_use() operate. Right here is an instance
of setting GPT 4 because the default:

library(chattr)
chattr_use("gpt4")
chattr_app()

You can too choose a mannequin by setting the CHATTR_USE surroundings
variable.

Superior customization

It’s doable to customise many facets of your interplay with the LLM. To do
this, use the chattr_defaults() operate. This operate shows and units the
extra immediate despatched to the LLM, the mannequin for use, determines if the
historical past of the chat is to be despatched to the LLM, and mannequin particular arguments.

For instance, it’s possible you’ll want to change the utmost variety of tokens used per response,
for OpenAI you need to use this:

# Default for max_tokens is 1,000
library(chattr)
chattr_use("gpt4")
chattr_defaults(model_arguments = checklist("max_tokens" = 100))
#> 
#> ── chattr ──────────────────────────────────────────────────────────────────────
#> 
#> ── Defaults for: Default ──
#> 
#> ── Immediate:
#> • {{readLines(system.file('immediate/base.txt', bundle = 'chattr'))}}
#> 
#> ── Mannequin
#> • Supplier: OpenAI - Chat Completions
#> • Path/URL: https://api.openai.com/v1/chat/completions
#> • Mannequin: gpt-4
#> • Label: GPT 4 (OpenAI)
#> 
#> ── Mannequin Arguments:
#> • max_tokens: 100
#> • temperature: 0.01
#> • stream: TRUE
#> 
#> ── Context:
#> Max Knowledge Information: 0
#> Max Knowledge Frames: 0
#> ✔ Chat Historical past
#> ✖ Doc contents

If you happen to want to persist your modifications to the defaults, use the chattr_defaults_save()
operate. This can create a yaml file, named ‘chattr.yml’ by default. If discovered,
chattr will use this file to load the entire defaults, together with the chosen
mannequin.

Past the app

Along with the Shiny app, chattr provides a few different methods to work together
with the LLM:

• Use the chattr() operate
• Spotlight a query in your script, and use it as your immediate

> chattr("how do I take away the legend from a ggplot?")
#> You'll be able to take away the legend from a ggplot by including 
#> `theme(legend.place = "none")` to your ggplot code.

RStudio Add-ins

chattr comes with two RStudio add-ins:

You’ll be able to bind these add-in calls to keyboard shortcuts, making it straightforward to open the app with out having to jot down
the command each time. To learn to do this, see the Keyboard Shortcut part within the
chattr official web site.

Works with native LLMs

Open-source, skilled fashions, which can be capable of run in your laptop computer are broadly
obtainable right now. As an alternative of integrating with every mannequin individually, chattr
works with LlamaGPTJ-chat. This can be a light-weight utility that communicates
with a wide range of native fashions. Right now, LlamaGPTJ-chat integrates with the
following households of fashions:

• GPT-J (ggml and gpt4all fashions)
• LLaMA (ggml Vicuna fashions from Meta)
• Mosaic Pretrained Transformers (MPT)

LlamaGPTJ-chat works proper off the terminal. chattr integrates with the
utility by beginning an ‘hidden’ terminal session. There it initializes the
chosen mannequin, and makes it obtainable to start out chatting with it.

To get began, you must set up LlamaGPTJ-chat, and obtain a suitable
mannequin. Extra detailed directions are discovered
right here.

chattr seems for the situation of the LlamaGPTJ-chat, and the put in mannequin
in a selected folder location in your machine. In case your set up paths do
not match the areas anticipated by chattrthen the LlamaGPT is not going to present
up within the menu. However that’s OK, you may nonetheless entry it with chattr_use():

library(chattr)
chattr_use(
  "llamagpt",   
  path = "(path to compiled program)",
  mannequin = "(path to mannequin)"
  )
#> 
#> ── chattr
#> • Supplier: LlamaGPT
#> • Path/URL: (path to compiled program)
#> • Mannequin: (path to mannequin)
#> • Label: GPT4ALL 1.3 (LlamaGPT)

Extending chattr

chattr goals to make it straightforward for brand spanking new LLM APIs to be added. chattr
has two elements, the user-interface (Shiny app and
chattr() operate), and the included back-ends (GPT, Copilot, LLamaGPT).
New back-ends don’t should be added straight in chattr.
In case you are a bundle
developer and want to reap the benefits of the chattr UI, all you must do is outline ch_submit() technique in your bundle.

The 2 output necessities for ch_submit() are:

• As the ultimate return worth, ship the complete response from the mannequin you’re
  integrating into chattr.

• If streaming (stream is TRUE), output the present output as it’s occurring.
  Usually by way of a cat() operate name.

Right here is a straightforward toy instance that reveals how one can create a customized technique for
chattr:

library(chattr)
ch_submit.ch_my_llm <- operate(defaults,
                                immediate = NULL,
                                stream = NULL,
                                prompt_build = TRUE,
                                preview = FALSE,
                                ...) {
  # Use `prompt_build` to prepend the immediate
  if(prompt_build) immediate <- paste0("Use the tidyversen", immediate)
  # If `preview` is true, return the ensuing immediate again
  if(preview) return(immediate)
  llm_response <- paste0("You stated this: n", immediate)
  if(stream) {
    cat(">> Streaming:n")
    for(i in seq_len(nchar(llm_response))) {
      # If `stream` is true, be sure to `cat()` the present output
      cat(substr(llm_response, i, i))
      Sys.sleep(0.1)
    }
  }
  # Be certain to return your complete output from the LLM on the finish
  llm_response
}

chattr_defaults("console", supplier = "my llm")
#>
chattr("whats up")
#> >> Streaming:
#> You stated this: 
#> Use the tidyverse
#> whats up
chattr("I can use it proper from RStudio", prompt_build = FALSE)
#> >> Streaming:
#> You stated this: 
#> I can use it proper from RStudio
