promptwatch.io python client to trace langchain sessions

Project description

PromptWatch.io ... session tracking for LangChain

It enables you to:

  • track all the chain executions
  • track LLM Prompts and re-play the LLM runs with the same input parameters and model settings to tweak your prompt template
  • track your costs per project and per tenant (your customer)

Installation

pip install promptwatch

Basic usage

In order to enable session tracking wrap you chain executions in PromptWatch block

from langchain import OpenAI, LLMChain, PromptTemplate
from promptwatch import PromptWatch

prompt_template = PromptTemplate.from_template("Finish this sentence {input}")
my_chain = LLMChain(llm=OpenAI(), prompt=prompt_template)

with PromptWatch(api_key="<your-api-key>") as pw:
    my_chain("The quick brown fox jumped over")

Here you can get your API key: http://www.promptwatch.io/get-api-key (no registration needed)

You can set it directly into PromptWatch constructor, or set is as an ENV variable PROMPTWATCH_API_KEY

Comprehensive Chain Execution Tracking

With PromptWatch.io, you can track all chains, actions, retrieved documents, and more to gain complete visibility into your system. This makes it easy to identify issues with your prompts and quickly fix them for optimal performance.

What sets PromptWatch.io apart is its intuitive and visual interface. You can easily drill down into the chains to find the root cause of any problems and get a clear understanding of what's happening in your system.

LLM Prompt caching

It is often tha case that some of the prompts are repeated over an over. It is costly and slow. With PromptWatch you just wrap your LLM model into our CachedLLM interface and it will automatically reuse previously generated values.

LLM Prompt Template Tweaking

Tweaking prompt templates to find the optimal variation can be a time-consuming and challenging process, especially when dealing with multi-stage LLM chains. Fortunately, PromptWatch.io can help simplify the process!

With PromptWatch.io, you can easily experiment with different prompt variants by replaying any given LLM chain with the exact same inputs used in real scenarios. This allows you to fine-tune your prompts until you find the variation that works best for your needs.

Keep Track of Your Prompt Template Changes

Making changes to your prompt templates can be a delicate process, and it's not always easy to know what impact those changes will have on your system. Version control platforms like GIT are great for tracking code changes, but they're not always the best solution for tracking prompt changes.

Unit testing

Unit tests will help you understand what impact your changes in Prompt templates and your code can have on representative sessions examples.
