OpenAI API vs Claude
OpenAI API (developer platform) and Claude (Anthropic's consumer AI) both allow commercial use of outputs; the two differ primarily in product surface and default training-data treatment.
Key differences
- OpenAI API is a developer API; Claude is a consumer chat product.
- OpenAI API does not use inputs for training by default. Claude consumer training behavior depends on the plan tier.
- Output ownership is assigned to the customer / user in both cases, subject to usage policies.
