The Nox model family
Nox runs on a small family of purpose-built models. Each one is tuned for a different kind of question — from fast everyday answers to deep, cited research and real-time voice. Here's what each model does, what it's best at, and which plan you'll find it on.
Models
Nox Light 1.1
Fast, everyday health answers
Light 1.1 is the model behind everyday Nox chats. It is tuned for speed and clarity: ask a health question and get a direct, easy-to-read answer, usually in seconds. It is the default model on every plan, including Free.
Available on every plan, including Free.
Nox Thinking 1.1
Deeper reasoning for complex questions
Thinking 1.1 is Nox's reasoning model. Instead of answering immediately, it works through a question methodically — weighing several factors, spotting connections, and structuring its response — which makes it the better choice when a question has several moving parts.
Available on Pro and MAX.
Nox Agent 1.2 (Beta)
Deep research with live web sources
Nox Agent 1.2 (beta) is built for research. Instead of a single reply, it plans out a question, gathers information, and comes back with a clear answer plus resource cards you can open — each with a title, source, and link.
Available on Pro and MAX. Currently in beta.
Nox Voice 1.2 (Beta)
Talk to Nox in real time
Nox Voice 1.2 (beta) turns Nox into a live, phone-call-style conversation, built on leading conversational voice AI technology. Just talk and Nox replies in a natural voice, in real time — no typing.
Available on MAX. Currently in beta.
