06Role in a stackGeneral-purpose assistant baseline and multimodal draft criticLow-cost reasoning and coding assistant / API model option
07Best for
  • General-purpose drafting, critique, summarization, and multimodal exploration when you need the baseline assistant to compare against
  • Students who want one broad assistant for outlining, code help, file questions, images, audio, and study planning
  • Teams that can use Business/Enterprise controls rather than consumer chat for sensitive work
  • Workflows where connected services, GPTs/projects, Codex, and agents matter more than a narrow cited-search interface
  • Cost-sensitive API experiments where token price matters more than ecosystem polish
  • Coding and reasoning comparisons against ChatGPT, Claude, Gemini, Mistral, and OpenRouter routes
  • Developers who want OpenAI-/Anthropic-compatible endpoints for inexpensive model routing tests
  • Users who can keep sensitive or unpublished research out of consumer chat and standard API calls
08Avoid if
  • You need API-only usage and are evaluating API economics, not the chat subscription
  • Institutional data rules forbid consumer cloud processing or model-improvement use
  • You require no-training and retention guarantees without a Business, Enterprise, Edu, Healthcare, Teachers, or API agreement
  • Your deliverable is source-grounded research and you will not independently open and verify citations
  • Your institution bars sending research data to China-based AI services
  • You need clear enterprise data-residency, retention, or no-training guarantees for consumer chat
  • You want the most mature assistant ecosystem, integrations, admin controls, or procurement story
  • You cannot monitor model-name deprecations and API compatibility changes

Privacy facets

Where each tool is actually private.

Training on your dataPartialPartial: OpenAI may use your content from ChatGPT Free, Go, Plus and Pro to train its models by default. To opt out, turn off “Improve the model for everyone” in Settings > Data controls, or select “Do not train on my content” in OpenAI's Privacy Portal. ChatGPT Business, Enterprise, Edu and the API do not use inputs or outputs for training by default. If you send feedback, the entire conversation linked to it may still be used for training.
