Blaxel Langgraph Agent

A template implementation of a conversational agent using LangGraph and GPT-4. This agent demonstrates the power of LangGraph for building interactive AI agents with tool integration capabilities.

Features

• Interactive conversational interface
• Tool integration support (including weather and search capabilities)
• Streaming responses for real-time interaction
• Built on LangGraph for efficient agent orchestration
• Easy deployment and integration with Blaxel platform

Prerequisites

• Python: 3.10 or later
• UV: An extremely fast Python package and project manager, written in Rust
• Blaxel CLI: Ensure you have the Blaxel CLI installed. If not, install it globally:

  curl -fsSL https://raw.githubusercontent.com/beamlit/toolkit/main/install.sh | BINDIR=$HOME/.local/bin sh

• Blaxel login: Login to Blaxel platform

  bl login YOUR-WORKSPACE

Installation

Clone the repository and install dependencies:

git clone https://github.com/beamlit/template-langgraph-py.git
cd template-langgraph-py
uv sync

Running the Server Locally

Start the development server with hot reloading:

bl serve --hotreload

Note: This command starts the server and enables hot reload so that changes to the source code are automatically reflected.

Testing your agent

You can test your agent using the chat interface:

bl chat --local blaxel-agent

Or run it directly with specific input:

bl run agent blaxel-agent --local --data '{"input": "What is the weather in Paris?"}'

Deploying to Blaxel

When you are ready to deploy your application:

bl deploy

This command uses your code and the configuration files under the .blaxel directory to deploy your application.
