Think Fast with GPT-5 Nano
The smallest, fastest model in the GPT-5 family — perfect for instant answers, real-time chat, and everyday AI tasks at ultra-low cost
Instant Answers Without the Wait
GPT-5 Nano is built for the moments when you need a response right now. Whether you're asking a quick factual question, looking up something mid-conversation, or need a fast first draft of a short message, Nano delivers with the speed and accuracy you expect from the GPT-5 family. It skips the processing overhead of larger models while maintaining the same quality instruction-following that GPT-5 is known for, making every interaction feel snappy and natural rather than slow and deliberate.
Handles Everyday Tasks With Ease
The vast majority of things people use AI for on a daily basis don't require a frontier-scale model. Summarizing a paragraph, rewording a sentence, answering a trivia question, translating a phrase, checking grammar, or drafting a quick reply to an email — GPT-5 Nano handles all of these with the same quality you'd expect from a much larger model, at a fraction of the cost and latency. Inside Chat Smith, Nano is your go-to for anything routine that just needs to get done quickly and correctly.
Real-Time Conversations That Stay Sharp
GPT-5 Nano's low latency makes it ideal for the kind of back-and-forth conversations where waiting a few extra seconds would break the flow. It keeps up with rapid exchanges, maintains context across multiple turns, and gives you coherent, accurate follow-ups even in extended dialogue. Whether you're brainstorming ideas, working through a quick problem, or just having a casual exchange with an AI assistant, Nano keeps the conversation moving at a pace that feels natural and responsive.
Native Vision for Text and Image Tasks
GPT-5 Nano supports native vision, meaning you can send an image alongside your message and get an intelligent response that considers both the visual and textual content together. Upload a photo, a screenshot, a chart, or a scanned document and ask about it — Nano analyzes the image and provides accurate, contextually aware answers. This makes it genuinely useful for visual tasks without having to switch to a larger model, keeping things fast and cost-effective for everyday multimodal interactions.
400K Context That Keeps Up With You
Despite being the smallest in the GPT-5 family, Nano supports a 400,000-token context window — large enough to hold long conversation histories, process substantial documents, or work through extended tasks without losing track of earlier details. You won't hit a wall mid-conversation or have to repeat yourself because the model forgot what was discussed earlier. For daily use and real-time applications, this context capacity makes Nano a genuinely capable companion rather than a limited shortcut model.
