ChatGPT for business: plans, models and practical evaluation
ChatGPT supports research, drafts and work with files. Choose according to the access route, approved data and effort needed to produce a checked result.

Models and access
OpenAI lists GPT-5.6 and GPT-6 Pro in ChatGPT. Availability depends on plan, interface, rollout and workspace permissions. Access in Work or Codex does not automatically mean identical access in Chat. Check the current model guide for your account.
Compare actual costs
Free, Go, Plus, Pro, Business and Enterprise differ in access and limits. Check the current total price, currency, taxes, billing period, seats and extra usage with the provider. A ChatGPT subscription is not general API credit. Compare cost per approved result, including human rework.
Data and permissions
OpenAI does not train on Business, Enterprise or API business data by default. This is not blanket privacy clearance: separately check the contract, permitted data, retention, region, apps and permissions. Zero Data Retention is not a general feature of every ChatGPT plan.
Your practical evaluation
Sources checked 16 September 2026. Editorial guide without our own benchmark score. Linked reports may have different review dates.
- Choose three approved tasks: summarize a document with references, analyze a spreadsheet and draft a customer response.
- Use identical inputs and acceptance criteria; record model, plan, settings and date.
- Measure factual errors, source coverage, numerical accuracy and correction time. Open citations and check whether they support the claim.
- Require human approval before external sending or business-system changes. Test costs, permissions and failure cases before rollout.
