model-compose: Declarative AI Workflow Orchestrator

한국어 | 中文

---

🤖 Model-Compose

model-compose is a declarative AI workflow orchestrator inspired by docker-compose. It lets you define and run AI model pipelines using simple YAML files — no custom code required. Effortlessly connect external AI services (OpenAI, Anthropic, Google, etc.), run local AI models, integrate vector stores, and more — all within powerful, composable workflows.

No custom code. Just YAML configuration.

✨ Features

🎨 No-Code AI Orchestration

Define complex AI workflows entirely in YAML—no Python, no JavaScript, no coding required. Connect multiple AI services, models, and APIs through simple declarative configuration.

🔗 Universal AI Service Integration

Connect to any AI provider out of the box—OpenAI, Anthropic Claude, Google Gemini, ElevenLabs, Stability AI, Replicate, or any custom HTTP API. Mix and match services in a single workflow.

🤖 Agent Components

Build autonomous AI agents that use workflows as tools. Agents can reason, plan, and execute multi-step tasks by dynamically invoking other workflows—all defined declaratively in YAML.

✋ Human-in-the-Loop

Add approval gates and user input steps to any workflow with interrupt configuration. Workflows pause, prompt for human input via CLI, Web UI, or API, and resume seamlessly—perfect for review, moderation, and supervised AI pipelines.

🖥️ Local Model Execution

Run models from HuggingFace and other sources locally with native support for transformers, PyTorch, and model serving frameworks. Fine-tune models with LoRA/PEFT, train with custom datasets, all through YAML configuration.

⚡ Real-Time Streaming

Built-in SSE (Server-Sent Events) streaming for real-time AI responses. Stream from OpenAI, Claude, local models, or any streaming API with automatic chunking and connection management.

🔄 Advanced Workflow Composition

Build multi-step pipelines with conditional logic, data transformation, and parallel execution. Pass data between jobs with powerful variable binding—${input}, ${response}, ${env}, with type conversion and defaults.

🚀 Production-Ready Deployment

Deploy as HTTP REST API or MCP (Model Context Protocol) server by changing one line. Includes concurrency control, health checks, and automatic API documentation.

🎯 Event-Driven Architecture

HTTP Callback listeners for async workflows (image generation, video processing). HTTP Trigger listeners for webhooks and external events. Build reactive AI systems that respond to real-world events.

🌐 Smart Tunneling & Gateways

Expose local services to the internet instantly with ngrok, Cloudflare, or SSH tunnels. Perfect for webhook integration and public API deployment without complex networking.

🐳 Container-Native Deployment

First-class Docker support with runtime configuration, volume mounting, and environment management. Deploy to any cloud provider or Kubernetes cluster with minimal configuration.

🎨 Instant Web UI

Add a visual interface with just 2 lines—get Gradio-powered chat UI or serve custom static frontends. Test workflows, monitor executions, and debug pipelines visually.

🗄️ RAG & Vector Database Ready

Native integration with ChromaDB, Milvus, Pinecone, and Weaviate. Build retrieval-augmented generation (RAG) systems with embedding search, document indexing, and semantic retrieval.

🔧 Flexible Component System

Reusable components with multi-action support. Define once, use everywhere. Mix HTTP clients, local models, vector stores, shell commands, and custom workflows in any combination.

📦 Installation

pip install model-compose

Or install from source:

git clone https://github.com/hanyeol/model-compose.git
cd model-compose
pip install -e .

Requires: Python 3.9 or higher

---

🚀 Quick Start

Create a model-compose.yml:

controller:
  type: http-server
  port: 8080
  webui:
    port: 8081

workflows:
  - id: chat
    default: true
    jobs:
      - component: chatgpt

components:
  - id: chatgpt
    type: http-client
    base_url: https://api.openai.com/v1
    path: /chat/completions
    method: POST
    headers:
      Authorization: Bearer ${env.OPENAI_API_KEY}
    body:
      model: gpt-4o
      messages:
        - role: user
          content: ${input.prompt}

Create a .env file:

OPENAI_API_KEY=your-key

Run it:

model-compose up

Your API is now live at http://localhost:8080 and Web UI at http://localhost:8081 🎉
