🦙 LlamaDeploy 🤖

LlamaDeploy (formerly llama-agents) is an async-first framework for deploying, scaling, and productionizing agentic multi-service systems based on workflows from llama_index. With LlamaDeploy, you can build any number of workflows in llama_index and then run them as services, accessible through a HTTP API by a user interface or other services part of your system.

The goal of LlamaDeploy is to easily transition something that you built in a notebook to something running on the cloud with the minimum amount of changes to the original code, possibly zero. In order to make this transition a pleasant one, you can interact with LlamaDeploy in two ways:

• Using the llamactl CLI from a shell.
• Through the LlamaDeploy SDK from a Python application or script.

Both the SDK and the CLI are part of the LlamaDeploy Python package. To install, just run:

pip install -U llama-deploy

Why LlamaDeploy?

1. Seamless Deployment: It bridges the gap between development and production, allowing you to deploy llama_index workflows with minimal changes to your code.
2. Flexibility: By using a hub-and-spoke architecture, you can easily swap out components (like message queues) or add new services without disrupting the entire system.
3. Fault Tolerance: With built-in retry mechanisms and failure handling, LlamaDeploy adds robustness in production environments.
4. Async-First: Designed for high-concurrency scenarios, making it suitable for real-time and high-throughput applications.

[!NOTE] This project was initially released under the name llama-agents, but the introduction of Workflows in llama_index turned out to be the most intuitive way for our users to develop agentic applications. We then decided to add new agentic features in llama_index directly, and focus LlamaDeploy on closing the gap between local development and remote execution of agents as services.

Quick Start with llamactl

Spin up a running deployment in minutes using the interactive CLI wizard:

# 1. Install the package & CLI
pip install -U llama-deploy

# 2. Scaffold a new project (interactive)
llamactl init

#    or non-interactive
llamactl init --name project-name --template basic

# 3. Enter the project
cd project-name

# 4. Start the control-plane API server (new terminal)
python -m llama_deploy.apiserver

# 5. Deploy the generated workflow (another terminal)
llamactl deploy deployment.yml

# 6. Call it!
llamactl run --deployment hello-deploy --arg message "Hello world!"
