Mini toolsGPT 4.1 nano
By OpenAI
Model family: GPT
GPT-4.1 nano is optimized for environments where speed, cost, and footprint are critical. With a dramatically smaller parameter count, it can run efficiently on mobile devices, laptops, or cost-constrained cloud instances. It’s capable of everyday reasoning, summarization, text transformation, and lightweight Q&A, but is not designed for the deepest analytical or coding tasks that its larger siblings handle.
Nano supports structured outputs and function calls, enabling it to fit into agent frameworks and automation pipelines even in resource-restricted deployments. Typical applications include mobile chat assistants, customer service bots, embedded copilots in apps, and real-time automation tasks where responsiveness matters more than exhaustive reasoning.

Warp is probably the best CLI on the Mac Platform, even better when you are in the middle of that complex linux string and you think How do I...just ask the AI and it will give you that answer you forget all those years ago.
