GPT-5.4 brings powerful reasoning, coding, and agentic workflows into one frontier model, now live in ChatGPT, API, and Codex. With GPT-5.4 mini (2x faster) and nano (lowest cost), build responsive AI systems for coding, subagents, and multimodal tasks. Featuring computer use, web search, and massive context, it’s designed for real-world, high-scale execution.

ChatGPT for Excel builds full spreadsheets from plain language, analyzes data across tabs and formulas, and updates your workbook in real time. It explains every change, links answers to the cells it touches, and asks before editing. Fix errors, spot patterns, and turn raw data into insights without switching tools. Same Excel. Smarter workflows.

GPT-5.4 Thinking delivers deeper web research, stronger context retention on long tasks, and 33% fewer factual errors than its predecessor. You can now interrupt the model mid-response and redirect it. No need to start over. Same intelligence. More control. Less token burn by default.

GPT‑5.2 is designed to unlock even more economic value for people; it’s better at creating spreadsheets, building presentations, writing code, perceiving images, understanding long contexts, using tools, and handling complex, multi-step projects.

One agent for everywhere you code—included in ChatGPT Plus, Pro, Business, Edu, and Enterprise plans.

For developers who live in the terminal and want ChatGPT‑level reasoning plus the power to actually run code, manipulate files, and iterate – all under version control. In short, it’s chat‑driven development that understands and executes your repo.

A new way to ask ChatGPT to do things for you at a future time. Whether it's one-time reminders or recurring actions, tell ChatGPT what you need and when, and it will automatically take care of it.

With ChatGPT in your pocket, you’ll find:

· Instant answers · Tailored advice · Creative inspiration · Professional input · Learning opportunities

Initial support for plugins in ChatGPT that are designed specifically for language models with safety as a core principle, and help ChatGPT access up-to-date information, run computations, or use third-party services.

Open AI has just announced plugins for ChatGPT. From now it will be possible to inject real-world and real-time data into the ChatGPT context. Some examples are available online for preview, and developers will have access to the API soon.
