Ptero
AI Chat with powerful models for free
Ptero is a free, open-source multi-model AI chat platform built around a simple browser interface. It provides access to several language-model families, including DeepSeek, Llama, Qwen, MiniMax, and Mistral. Users can switch models quickly to compare responses without creating an account. Conversations are stored locally in the browser rather than saved as server-side chat history.
