ChatGPT

ChatGPT is OpenAI's conversational AI assistant and, through its Business and Enterprise tiers, a governed workspace for deploying frontier models across an organisation. It combines chat, voice, image generation, Deep Research and an agentic mode with admin controls, SSO, audit logs and permission-aware connectors to internal document stores, removing the need for every team to build its own assistant.

ChatGPT is OpenAI's conversational AI assistant, released 30 November 2022 and now the most widely used AI product in the world, reaching 900 million weekly active users by February 2026. It exposes OpenAI's frontier models — GPT-5.5 and GPT-5.6 as of mid-2026, with GPT-4.5, o3 and GPT-5 retired on OpenAI's own schedule — through a chat interface, voice mode, image generation, Deep Research and an agentic Agent mode that browses and executes multi-step tasks. For organisations the relevant products are ChatGPT Business and ChatGPT Enterprise rather than the consumer tiers. Both add an admin console, SAML SSO, SCIM provisioning, role-based access control, audit logging and a contractual commitment that business data is not used to train OpenAI models by default. Enterprise adds a HIPAA business associate agreement on request, Enterprise Key Management, US or EU data residency, a Compliance API, priority access to new models and no per-user message caps. Company knowledge connectors — SharePoint, Google Drive, Dropbox, Box, Teams, Gmail, Slack, GitHub and Linear — let answers cite internal documents while respecting source-system permissions; OpenAI began renaming connectors to apps in December 2025. The commercial shape is unusual: Business is self-serve at $20–25 per seat with a two-seat minimum, while Enterprise is quote-only, typically $45–75 per seat per month with a reported 150-seat minimum and annual prepayment, putting the practical entry point near $108,000 a year. Enterprise now accounts for more than half of OpenAI's revenue, which passed a $40 billion annualised run rate in 2026.

• ✓
  Company knowledge connectors

  Syncs SharePoint, Google Drive, Dropbox, Box, Teams, Gmail, Slack, GitHub and Linear so answers cite internal documents while honouring each source system's existing permissions.

• ✓
  Admin console with SSO and SCIM

  Centralised workspace administration with SAML single sign-on, SCIM provisioning, role-based access control and department-level usage analytics for IT owners.

• ✓
  Agent mode and Deep Research

  Runs multi-step browsing and analysis tasks autonomously, returning cited research reports rather than a single-turn answer, which is what most analyst work actually needs.

• ✓
  Enterprise data controls

  Business data is excluded from model training by default, with AES-256 encryption at rest, TLS 1.2+ in transit, audit logs and configurable retention.

• ✓
  Enterprise Key Management and data residency

  Customer-managed encryption keys plus US or EU data residency options for regulated buyers, though enabling EKM turns off the synced connectors.

• ✓
  Custom GPTs and shared workspace assets

  Teams publish org-wide custom GPTs and shared prompt templates so a working configuration spreads instead of being rebuilt by every department.

• •
  Sanctioned assistant rollout

  IT replaces unmanaged personal ChatGPT accounts with an SSO-governed workspace, regaining visibility over what corporate data employees are pasting into an AI tool.

• •
  Internal knowledge retrieval

  Employees ask policy, product or process questions and receive answers cited to the SharePoint and Drive documents they are already permitted to open.

• •
  Contract and document triage

  Legal and procurement teams summarise long agreements and flag clause deviations for human review, cutting first-pass reading time on routine paperwork.

• •
  Research and competitive briefings

  Strategy teams use Deep Research to compile multi-source market briefings with inline citations, replacing several hours of manual tab-by-tab searching.

• •
  Engineering assistance through Codex

  Developers delegate test generation, refactors and code review passes to Codex agents, billed from a usage pool above the included baseline.

Business is self-serve at $20/seat/month billed annually or $25 monthly with a two-seat minimum, and OpenAI cut that by $5 in April 2026. Enterprise publishes no list price at all: 2026 procurement reporting converges on $45-75 per seat per month, around $60 typical, with a reported 150-seat minimum and annual prepayment — a practical floor near $108,000 a year even if only fifty people need it. Volume discounts of roughly 10-25% are reported above 300 and 500 seats, with a further 5-15% for multi-year terms. Budget separately for Codex consumption above the included baseline, which is hard to forecast without pilot data, and for custom integrations to systems with no native connector, commonly $10,000-$50,000+. There is no free trial of Enterprise; Business is the closest self-serve path.
