Installation

pip install reminix-llamaindex

This will also install reminix-runtime as a dependency.

Quick Start

from llama_index.core.chat_engine import SimpleChatEngine
from llama_index.llms.openai import OpenAI
from reminix_llamaindex import serve_agent

llm = OpenAI(model="gpt-4o")
engine = SimpleChatEngine.from_defaults(llm=llm)
serve_agent(engine, name="my-chatbot", port=8080)

For more flexibility (e.g., serving multiple agents), use wrap_agent and serve separately:

from llama_index.core.chat_engine import SimpleChatEngine
from llama_index.llms.openai import OpenAI
from reminix_llamaindex import wrap_agent
from reminix_runtime import serve

llm = OpenAI(model="gpt-4o")
engine = SimpleChatEngine.from_defaults(llm=llm)
agent = wrap_agent(engine, name="my-chatbot")
serve(agents=[agent], port=8080)

Your agent is now available at:

• POST /agents/my-chatbot/invoke - Execute the agent

Example with RAG

from llama_index.core import VectorStoreIndex, SimpleDirectoryReader
from llama_index.llms.openai import OpenAI
from reminix_llamaindex import wrap_agent
from reminix_runtime import serve

# Load documents and create index
documents = SimpleDirectoryReader("./data").load_data()
index = VectorStoreIndex.from_documents(documents)

# Create a chat engine with the index
engine = index.as_chat_engine(llm=OpenAI(model="gpt-4o"))

# Wrap and serve
agent = wrap_agent(engine, name="rag-chatbot")
serve(agents=[agent], port=8080)
