OpenAI's GPT-5 Nano, released in August 2025, is a compact model designed for environments requiring rapid interactions and ultra-low latency. It operates with a context length of 400,000 tokens, handling both text and image inputs, and producing text outputs. This model is particularly suited for developer tools and real-time applications, offering a lightweight solution without sacrificing essential instruction-following and safety features. While its reasoning depth is less than larger models, it's an excellent choice for cost-sensitive projects needing efficient performance.

Prompt:
Write 150 words on how AI might positively upend work, leisure and creativity
AI promises to positively upend work, leisure, and creativity by acting as a capable partner rather than a distant substitute. In the workplace, smart assistants automate repetitive tasks, summarize complex reports, and illuminate unseen trends, freeing people to focus on strategy, mentorship, and meaningful problem solving. Teams can work across time zones with adaptive scheduling, while decision support tools reduce bias through data transparency and scenario testing. For leisure, AI personalizes experiences, curates content, and enables safer exploration of new hobbies, from travel itineraries to fitness coaching and language practice. In creativity, AI becomes a collaborative studio: suggesting prompts, composing drafts, refining styles, and running rapid iterations on prototypes. The result is a culture of experimentation, where risk is mitigated and iteration accelerates learning. When guided by ethics and human judgment, AI amplifies empathy, inclusivity, and skill development, helping people craft better work, richer leisure, and more expressive art today.
