General AI models are powerful but often too broad for specific tasks. A service could let users fine-tune models on their data for specialized domains.
Create a web interface where users upload data, select base models, and get API access to their custom version. Charge per fine-tuning run and API calls.
Start with just Sonnet support, manually triggered fine-tuning jobs, and basic monitoring.
The risk is cloud providers eventually offering this natively - differentiate with specialized templates and vertical focus.
