Lytix supports capturing custom LLM traces (e.g. not associated with any SDK or API call). This is useful if you have custom models you’d still like to track. 
from lytix_py import lytix


@lytix.trace(modelName="nodeCli")
async def getResponse(logger):
    modelOutput = "Paris is the capital of France"

    # Set our defined params however we want
    lytix.setMessage("Some user input", "user")
    lytix.setMessage(modelOutput, "assistant")

    # Optional values
    lytix.setUserIdentifier("testUser")
    lytix.setSessionId("testSession")

    return modelOutput
