ChatGPT Plus vs Business: Models, Context, Data and Workspace Compared

Compare ChatGPT Plus and Business using OpenAI's official pricing pages: models, context window, Codex, data training, team workspace and connectors, plus what to watch for with ready-made accounts.

Short answer: pick Plus for personal daily use, custom GPTs and memory; pick Business if you need your data kept out of training or want to connect work tools like Slack and GitHub. Facts below come from OpenAI's official pricing pages, checked in November 2026.

What each plan is

Plus: a personal plan, positioned by OpenAI for advanced work and productivity.

Business: one seat in a team workspace, aimed at teams of 2 to 200 with central admin and billing.

Models and context

Plus gets the GPT-6 reasoning models with a 256K total reasoning context window.

A Business standard seat gets models such as GPT-6.1 Sol and GPT-6 Astra with flexible usage under workspace rules; reasoning context is also 256K, with about 320 pages of input.

Both include Codex and ChatGPT Work. OpenAI says that from December, Business usage is a shared limit across ChatGPT and Codex.

Data and privacy

Plus: conversations may be used to improve models by default; you can turn this off in settings.

Business: OpenAI does not train on your business data by default, and SAML SSO and MFA are supported.

What only Business adds

Connectors for Google Workspace, Slack, GitHub, Microsoft 365 and more.

Shared projects so teammates work in the same project.

Workspace agents for custom team workflows.

Where Plus suits individuals better

Custom GPTs, scheduled tasks and expanded memory and context.

Deep research and image generation limits are plenty for one person.

The account is yours alone, with no workspace rules.

Buying a ready-made account

A Business account is a seat in a workspace: do not add members, or you may be removed with no refund.

For either plan, change the password and replace 2FA right after signing in, and never turn 2FA off.

Current plans and warranty are listed on the product page.

A quick way to decide

List the three things you do most. If they are personal writing, study and research, choose Plus; if you want to plug company docs or code repositories into ChatGPT, or need data kept out of training, choose Business. Test the context window with this prompt:
