MultiO

MultiO gives you every top AI model — GPT, Claude, Gemini, Grok and Llama — under one subscription instead of five. With Auto routing, each message goes to the most cost-efficient model that can handle it, or pin a flagship. Every message carries a receipt showing its exact token charge, and Compare lets you ask three models side by side. Plus deep research, image/video generation, live voice, a GitHub code assistant, and a developer API. Free trial: 3,000,000 tokens, no card. Pro is $20/month.
