How billing works
Your balance is in USD. When you add $5, you get exactly $5 worth of model usage at OpenRouter's published rates. We add nothing on top.
Prices change as OpenRouter updates them. For current per-model rates, see openrouter.ai/models. Or paste your own API key from any of the 20+ supported providers (OpenAI, Anthropic, Google, etc.) in Settings. No OpenYak account needed.

How does billing work?
Your balance is in USD. When you top up $5, you get $5 of model usage at the exact same token prices as OpenRouter. Zero markup — we're open-source.
Does my balance expire?
No. Your balance never expires and there's no subscription. Top up once, use anytime.
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, pay-as-you-go balance, 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.
