How do cloud models work?
OpenYak does not resell model access. Use your own API keys, your own OpenRouter key, your ChatGPT subscription, or local models through Ollama.
What setup is required?
Download the desktop app, choose a local model or paste a provider key, and keep control on your machine.
What free models are available?
All free-tier models on OpenRouter, including Llama, Gemma, Mistral community models, and more. You can also run any model for free locally via Ollama.
Can I switch between modes?
Yes. You can use free models, your own API keys from 20+ providers, your ChatGPT subscription, or local Ollama models — all interchangeably. Switch anytime in settings.
Is my data private?
Yes. OpenYak is local-first. Your conversations and files are stored only on your machine. When using cloud models, only API calls to LLM providers leave your computer. When using local models via Ollama, nothing leaves your machine at all.
