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.

ChatGPT Images is powered by the new GPT Image 1.5 model. It delivers precise edits that preserve lighting and facial likeness, stronger instruction following, and 4x faster generation. Available now in ChatGPT and via API.

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.

Group chats are now in ChatGPT. You can add friends, family, or coworkers to a shared conversation to collaborate, plan, and create together with AI. It's separate from your private chats.

GPT-5.1 Instant and Thinking are trained using the same stack as OpenAI's reasoning models, so they score higher on factuality and complex problem-solving than GPT-5, while also introducing a more natural, conversational tone. We think many people will find that GPT-5.1 does a better job of bringing IQ and EQ together, but one default clearly can’t meet everyone’s needs.
