nerif 0.9.4

LLM powered Python

Nerif

Program with both Python and Natural Language.

LLMs can be tricky to work with. They sometimes give overly formal responses or get confused when they're unsure, making them challenging to use in real applications.

That's why we built Nerif - a simple tool that connects LLMs with Python code. We want to make it better than existing tools like Langchain and Dify.

Nerif helps you:

• Control exactly how LLMs work in your code
• Convert LLM responses into usable data formats
• Track performance with metrics like cost and success rate

Our goal is to make LLMs easier to use for developers, turning complex AI capabilities into practical programming tools.

How to install

Pre-requisite

• Python >= 3.9
• Environment variable OPENAI_API_KEY or other LLM API keys, for more details, see here
• Set default model and embedding model with NERIF_DEFAULT_LLM_MODEL and NERIF_DEFAULT_EMBEDDING_MODEL, for more details, see here

Example:

export OPENAI_API_KEY=`your_api_key`
export NERIF_DEFAULT_LLM_MODEL=gpt-4o
export NERIF_DEFAULT_EMBEDDING_MODEL=text-embedding-3-small

Install

pip install nerif

QuickStart

from nerif.core import nerif
from nerif.model import SimpleChatModel

model = SimpleChatModel()
# Default model is `gpt-4o`

# Use nerif judge "natural language statement"
if nerif("the sky is blue"):
    print("True")
else:
    # Call a simple model
    print("No", end=", ")
    print(model.chat("what is the color of the sky?"))
