Install Weave:
pip install weave
-
Import and initialize:
import weave weave.init("my-project-name")
-
Trace your functions:
@weave.op() def my_function(): # Your tracked code! pass
You can trace any function using weave.op()
- from api calls to OpenAI, Anthropic, Google AI Studio etc to generation calls from Hugging Face and other open source models to any other validation functions or data transformations in your code you'd like to keep track of.
Decorate all the functions you want to trace, this will generate a trace tree of the inputs and outputs of all your functions:
import weave
weave.init("weave-example")
@weave.op()
def sum_nine(value_one: int):
return value_one + 9
@weave.op()
def multiply_two(value_two: int):
return value_two * 2
@weave.op()
def main():
output = sum_nine(3)
final_output = multiply_two(output)
return final_output
main()
import weave
import json
from openai import OpenAI
@weave.op()
def extract_fruit(sentence: str) -> dict:
client = OpenAI()
response = client.chat.completions.create(
model="gpt-3.5-turbo-1106",
messages=[
{
"role": "system",
"content": "You will be provided with unstructured data, and your task is to parse it one JSON dictionary with fruit, color and flavor as keys."
},

Interested in pulling back the hood or contributing? Awesome, before you dive in, here's what you need to know.
We're in the process of 🧹 cleaning up 🧹. This codebase contains a large amount code for the "Weave engine" and "Weave boards", which we've put on pause as we focus on Tracing and Evaluations.
The Weave Tracing code is mostly in: weave/trace
and weave/trace_server
.
The Weave Evaluations code is mostly in weave/flow

The goal is to allow researchers to have a baseline of how well their model and entire inference pipeline is doing against different harm categories and to be able to compare that baseline to future iterations of their model. This allows them to have empirical data on how well their model is doing today, and detect any degradation of performance based on future improvements.
