AI21 Labs
DEVELOPER / CODING
PROMPT
API customers own all prompts and inputs submitted to AI21 Labs models. AI21 Labs processes inputs to generate text outputs.
OUTPUT
API customers own the outputs generated by AI21 models. AI21 Labs does not assert IP over API outputs.
TRAINING
The AI21 Labs Website ToS grants AI21 a 'worldwide, irrevocable, non-exclusive, royalty-free, perpetual, sublicensable (through multiple tiers), and transferable right and license' to use 'Your Content' for AI21's business. However, the Privacy Policy explicitly states: 'not use data obtained from these APIs to develop, improve, or train any machine learning or AI models beyond the user's own personalized experience.' This API-specific no-training commitment materially limits the broad website ToS license for API customers. The website ToS covers non-commercial personal use of the website; enterprise API governed by separate agreements.
COMMERCIAL
Commercial use is fully permitted for API customers. AI21's Jurassic models and Wordtune are used commercially.
