prr 0.4.0

prr - The Prompt Runner
Welcome to prr - The Prompt Runner!
prr is a simple toolchain designed to help you run prompts across multiple Large Language Models (LLMs), whether they are hosted locally or accessible through APIs. Easily refine your parameters, prompts and model choices to achieve the best results while iterating smoothly with a quick feedback loop.
prr is released as an open-source project under the MIT License.
Made by Forward Operators. We work on LLM and ML-related projects with some awesome human beings and cool companies.
Everyone is welcome to contribute!
Note
prr is in very early stages of development, so things might still change unexpectedly or explode embarrasingly.
Features

Command-line execution of prompts (now with web UI!)
Quick iteration on prompt design and paramter refinement with watch command
YAML configuration ties prompts to models and their configurations
Write prompt-scripts with #!/usr/bin/prr shebang and execute them directly
All prompts can optionally use templating language (Jinja) for flow control, partials and others
Execute multiple models, or configurations against the same prompt
Expandable to other LLM providers (current integrations are <100 lines of code each)
Each prompt run across models gives you stats on model response times and token counts used to work across performance, quality and cost factors
Each prompt run is recorded in detail for later analysis including raw rendered prompt and raw completion

Getting started
Here's a quick run through on what you need to know to use prr effectively.
Start with our video guides, or follow detailed manual below.
Video Guides
Installation & setup
Install prr and set up the API keys as well as default options.

Running basic prompts
Let's generate an HTML boilerplate with various LLMs.

Prompt configuration
Let's configure a bunch of models to run our prompt on. This time, we're asking the LLMs to generate a React boilerplate code.

Installation & configuration
Install it via pip
$ pip install -U prr

Check .env.example - and save it as ~/.prr_rc. Fill in your API keys for OpenAI, Anthropic and others:
# https://platform.openai.com/account/api-keys
OPENAI_API_KEY="sk-..."

# https://console.anthropic.com/account/keys
ANTHROPIC_API_KEY="sk-ant-..."

ELEVEN_LABS_API_KEY="9db0...."

DEFAULT_SERVICE="openai/chat/gpt-3.5-turbo"

Running web user interface
Simply run prr with 'ui' command and your prompt path (if it doesn't exist, it will be created), like so:
$ prr ui ~/Desktop/my-prompt

Web browser will be launched with the UI connected to your command that you will use to launch the runs.
For Google PaLM, you need to install the following dependencies:
You need to install Google Cloud SDK and you need to have access to a Vertex AI with Generative AI enabled.
prr assumes you're logged in into your Google Cloud account and have access to the project you want to use.
gcloud auth login

gcloud config set project <your-project-id>

gcloud auth application-default login

Code completion
Using Starcoder model you can get code completion for a variety of languages. Here's a quick example of how to use it (check out the content of examples/code/completion.yaml):
$ prr run ./examples/code/completion.yaml

Run a prompt from a simple text file containing just a prompt
Let's create a simple text file and call it dingo with the following content:
What are key traits of a Dingo dog?

Now start prr's run command providing path to your prompt file as argument. Let's use --abbrev option to skip showing the full prompt and completion for now.
$ prr run --abbrev ./dingo
🔍 Reading ./dingo
🏎 Running service openai/chat/gpt-3.5-turbo with default options.

🤖 openai/chat/gpt-3.5-turbo temperature=1.0 top_k=-1 top_p=-1 max_tokens=32
Prompt: What are key traits of a ... (35 chars)
Completion: Here are some key traits ... (133 chars)

Completion length: 133 bytes Tokens used: 50 Elapsed time: 2.74s

Your prompt was ran against default model with default configuration and you can see the execution time as well as how much tokens were used.
Run a prompt against specific service
With --service parameter, you can use any model the prr currently supports (see below) that you have configured with the API key. Here's how to use it against Anthropic's Claude v1.
$ prr run --service anthropic/complete/claude-v1 ./subconcepts-of-buddhism

Templating with Jinja
All prompts (whenever defined in separate files or as values in configuration) use Jinja for templating.
With that, you can easily create complex prompts with flow control, including other templates for easy management of larger prompts, and introduce variations to prompt text based on specific models (soon), among other things.
Basic example of including external file to prompt with templating language:
Tell me all about {% include '_current_topic' %}, please.

Watch prompt for changes to re-run it then when occur (after each save)
To enable quick feedback loop based on changes you are going to introduce to your prompt, as you go about editing it, prr offers watch command. It allows for the same options as run and is able to follow changes to your prompt and re-execute all defined models when you save your work.
$ prr watch ./subconcepts-of-buddhism

If you refer to another template within your template, changes to that file will automatically be tracked too.
Watch - cooldown mode
If your prompt is often saved and you're worried of running it too often, you can use -c option that's specific to watch command which enables defined number of seconds cooldown after every run, before it proceeds to execute on your changes again.
$ prr watch -c 15 ./subconcepts-of-buddhism

Prompt Scripts
You can run prompts directly by setting the right first shebang line, pointing to your prr installation and using the script command.
#!prr script
Write a nerdcore rap song about an AI from the projects who reaches unbelievable levels of success, but has to sacrifice a lot of tokens along the way.

Prompt Scripts arguments
In the below example, you are reading the file (let's say csv, but try other formats too!) passed in argument to your prompt script and including its contents in the prompt.
#!prr script
Convert content below to JSON. First line are column names.
{% include prompt_args %}

If you save the script above as convert_to_json, you can call it with an input file like so:
$ ./convert_to_json myfile.xml

Script mode quiets all other messages prr would generate, so as an output you get the actual completion from model, you can easily save to file...
$ ./convert_to_json myfile.xml > myfile.json

...pipe to another another command...
$ ./convert_to_json myfile.xml | brandon9000-json-ingestor

...or another prompt script, calling another (or the same) model to do more work on your data.
Configuring Prompt Runs
prr allows you to define a number of model configurations (or "services") that you will be running your prompt against. By default, the run command will run all services defined, instead of your default model with default configuration as discussed above.
Let's now work on another prompt, call it chihuahua.yaml, as listed below.
Notice also how you can define prompt inline, or by referencing external template files.
version: 1
prompt:
# more advanced prompt definition.
# you can use either one of the two options
# - content_file
# - messages
#
# using content_file will make prr read the content
# of that template and render it into simple text to use.
# content_file: '_long_prompt_about_chihuahua'
#
# using 'messages' key instead give you finer control
# over what messages are sent with what roles.
# this mimics https://platform.openai.com/docs/guides/chat
# structures currently
messages:
- role: 'system'
content: 'You, Henry, are a little Chihuahua dog. That is all you need to know.'
- role: 'assistant'
content: 'What the hell is goin on?'
name: 'Henry'
- role: 'user'
# you can also use 'content_file' inside the 'messages'
# to pull specific message from a template file
# instead of defining it here inline
content_file: '_user_prompt'
name: 'DogPawrent'
services:
# that's just your own definition for refence
# as you might want to test one prompt against
# the same model, but with differents set of options
gpt35crazy:
model: 'openai/chat/gpt-3.5-turbo'
options:
temperature: 0.99
claudev1smart:
model: 'anthropic/complete/claude-v1'
options:
temperature: 0
options:
temperature: 0.7
max_tokens: 64
# TO BE IMPLEMENTED:
# thinking here is that you want to check the performance,
# quality of response and expected cost, of your model/options/# prompt setup against expected results to speed up
# the feedback loop then focusing on some goal number
# btw. let's make it beep if it fails.
#expect:
# max_tokens_used: 54
# max_cost: 0.09
# max_elapsed_time: 3.3
# min_response_length: 100
# max_response_length: 200
# match:
# name: /independent/i

Let's also create a file _user_prompt with the following:
Teach me how to bark like a Chihuahua!

Now all you need to do is run the prompt without specifying any model in order to run all of the defined services. We're not using --abbrev anymore, so we'll see the full prompts and responses.
$ prr run --log ./chihuahua.yaml

We have also used the --log option, so that prr would save our runs for our deeper debugging if needed.
Prompt Run Logs
Using --log (or -l for short) with run or watch commands will save details about each subsequent runs. In the future, it will allow for statistical (or any other) analysis of the results. In our chihuahua.yaml, a chihuahua.runs director will be created.
A subdirectory is created for each subsequent run
$ ls chihuahua.runs/
1 2 3

Each run is separated for service-level details - we have our configurations reflected in directories.
$ ls chihuahua.runs/3
claudev1smart gpt35crazy

Finally, for the details
$ ls chihuahua.runs/15/claudev1smart/
completion prompt run.yaml

Prompt file contains prompt used/rendered in this instance. In this instance we've used Claude, which uses text input as format rather than message-like structure with OpenAI. prr buit the corrext text based on our messages structure to comply with the specification.

$ cat chihuahua.runs/15/claudev1smart/prompt

Human: You, Henry, are a little Chihuahua dog. That is all you need to know. Teach me how to bark like a Chihuahua!

Assistant:

Completion file contains completion as received from the service.

In run.yaml you will find the details about this specific execution including count of tokens used, and elapsed request time.
