Open AI 发布了 GPT-5.4 Mini 和 Nano 两个模型 把 GPT‑5.4 能力下放到更快、更便宜的小模型，用来当“执行层”和子 Agent 主力。

GPT‑5.4 mini：

• 定位即时响应的代码助手

• 大模型规划 + mini 并行执行的子智能体

• 解析复杂 UI 截图的 computer use

• 代码、推理、多模态、工具使用都有明显提升

• 定位速度 / 成本敏感的简单任务

• 分类、数据抽取、排序

• 简单辅助的子 Agent

价格：

GPT‑5.4 mini：0.75 / 4.50 美元百万 Token

GPT‑5.4 nano：0.20 / 1.25 美元百万 Token

One Sentence Summary

OpenAI has unveiled GPT-5.4 Mini and Nano, two compact models that extend GPT-5.4's capabilities to faster, more affordable execution layers and sub-agents, targeting instant-response code assistance and speed/cost-sensitive simple tasks, respectively.

Summary

This tweet provides a detailed interpretation of OpenAI's recently launched GPT-5.4 Mini and Nano models. These two models are designed to deliver the powerful capabilities of GPT-5.4 to developers in a more efficient and economical manner, serving as the primary 'execution layer' and 'sub-agents'. GPT-5.4 Mini is positioned as an instant-response code assistant, excelling in large model planning with mini parallel execution for sub-agents, computer vision for analyzing complex UI screenshots, and showing significant improvements across coding, reasoning, multimodal understanding, and tool use. GPT-5.4 Nano, on the other hand, focuses on speed and cost-sensitive simple tasks such as classification, data extraction, and sorting. The tweet also compares their performance tiers (GPT-5.4 > GPT-5.4 Mini ≈ GPT-5.4 Nano > GPT-5 Mini) and provides comprehensive pricing information.
