• OpenAI API Model API Sold on its own

  Hosted API for OpenAI's text, image, audio and embedding models, billed per token.

• ChatGPT Gov Application

  A version of ChatGPT that US government agencies deploy in their own Microsoft Azure commercial or Azure Government cloud, so the agency manages its own security, privacy and compliance.

• OpenAI Daybreak Agent platform

Inside ChatGPT

• ChatGPT for Word Application Included with the parent

  ChatGPT in a Microsoft Word sidebar: drafts, revises and reorganizes the open document from notes or pasted source text, pulling in context from connected apps like Outlook, SharePoint, Google Workspace and Dropbox.

• ChatGPT for Excel Application Included with the parent

  ChatGPT in the Excel ribbon: builds and edits spreadsheets, formulas and formatting from plain-language requests, answers questions about what is in the workbook, and asks permission before changing it. OpenAI's own page bundles this with a separate ChatGPT for Google Sheets add-in; this record covers the Excel add-in only.

• ChatGPT for PowerPoint Application Included with the parent

  ChatGPT in the PowerPoint ribbon: creates new slides, rewrites and restructures an existing deck, and turns notes, documents or spreadsheets into presentation-ready content while keeping the output editable in PowerPoint.

Inside ChatGPT plans
