OpenAI: GPT-5 Nano

GPT-5 Nano is the most compact and swift iteration within the GPT-5 ecosystem, specifically engineered for applications demanding high speed and minimal delay. It excels in scenarios like developer tools, real-time interactions, and environments where ultra-low latency is paramount. Despite its smaller size, it maintains core instruction-following and safety features, making it a reliable choice for efficient AI integration. This model is the direct successor to GPT-4.1-nano, offering a lightweight yet powerful option for cost-sensitive projects or applications requiring immediate responses. With a generous 400K token context window and a 4K token max output, it supports vision, functions, code, and streaming capabilities. Pricing is set at $0.05 per 1M input tokens and $0.40 per 1M output tokens, making it an accessible STARTER tier model on Multi AI.
