Imagine a single control room that orchestrates the most advanced AI minds—OpenAI's GPT-4, Anthropic's Claude, Google's Gemini, and dozens of open-source models—all from one elegant configuration file. V-Sync Hub is not another AI wrapper; it's a meta-orchestrator that transforms your terminal into a universal AI command center. Think of it as the umbilical cord connecting your creative intent to the universe of artificial intelligence, with zero friction and maximum flexibility.
This repository is a complete reimagining of the original vsync concept, evolved into a production-ready ecosystem for developers, researchers, and power users who refuse to be locked into a single AI provider.
The AI landscape is exploding like a supernova—new models emerge weekly, APIs change, pricing fluctuates, and your workflow gets fragmented across a dozen dashboards. V-Sync Hub solves this by acting as the gravitational center of your AI toolkit. One config file, one terminal command, and you can:
- Route prompts to the cheapest or most capable model automatically
- Compare responses from 5 different models simultaneously
- Build complex chains where GPT-4 generates, Claude refines, and Gemini formats
- Maintain a single point of authentication and billing management

The diagram above represents V-Sync Hub's core architecture—a modular routing system that treats every AI model as a pluggable "muscle fiber" connected to your central "brain" (the config file). The Response Aggregator acts as the symphony conductor, ensuring every voice is heard and harmonized before delivery.
- Python 3.9+ or Node.js 18+
- API keys for at least one supported provider (OpenAI, Claude, or Gemini)
- 10 MB free disk space

V-Sync Hub uses the 2024-10-01 API version by default. Configure your API key via environment variable:
export OPENAI_API_KEY="sk-your-key-here"Supported models include gpt-4-turbo, gpt-4o, gpt-3.5-turbo, and fine-tuned variants. The adapter supports:
- Function calling with automatic schema generation
- Vision capabilities (image analysis)
- Structured outputs with JSON mode
- Embeddings integration for semantic search
Anthropic's Claude API is supported natively with their Message API (v1). Configure via:
export ANTHROPIC_API_KEY="sk-ant-your-key-here"Key features enabled:
