Open source
AI tools for developers who live in the terminal.
Terminal-native AI agents from Calliope Labs, built for developers who live in the command line. Open source, multi-model, and designed to get out of your way.
Calliope AI CLI
One command to install. One command to run.
Install globally, run anywhere, use any model. First run walks you through setup, or bring a key and go.
Philosophy
The best AI tools feel like extensions of yourself.
AI should integrate into your workflow, not demand that you change it. Our open source tools meet you where you already are, in the terminal, with first-class multi-model support and zero lock-in.
Use Claude, GPT, Gemini, Mistral, or local models through Ollama. Switch providers mid-conversation. Your tools, your models, your choice.
CLI features
Multi-model AI in your terminal.
Multi-model
Claude, GPT, Gemini, Mistral, Ollama, and more. Switch between providers seamlessly.
Switch providers
Change AI providers with a single command: /provider anthropic, /provider openai, /provider google.
Autonomous loops
Run tasks to completion with /loop. Let the AI work until the job is done.
Persona modes
Calliope AI (creative), Professional, or Minimal. Choose the personality that fits your workflow.
Tool execution
Shell commands, file operations, and structured reasoning. Full system integration.
God mode
Run without permission prompts for trusted tasks. Maximum throughput when you need it.
Autonomous loops
Run complex tasks until completion.
The loop runs your prompt repeatedly, and each iteration sees the previous work. It stops when it outputs the completion promise or hits the iteration ceiling. Ideal for refactoring, migrations, or any task that needs several passes to finish.
Multi-model gateway
One gateway, twelve-plus providers.
The CLI runs on a unified model gateway. Hot-swap providers without code changes, and use the best model for each task.
Open core
MIT licensed. No lock-in.
Fork it, modify it, self-host it. Your code, your data, your choice. The CLI stays yours, forever.
The open source tools are the on-ramp to the wider platform. When your team needs governed, deployed, supported AI in production, that is where open core comes in.
