How this was valued: Face value of the documented general signup credit. No period normalization is shown because its expiry is not public, and the separate approval-only institutional program is excluded.

Approved institutions can receive additional inference access for up to one year, but the program does not publish a monetary allowance.

Not privateReviewed

Current free-service terms expressly allow storage, service improvement, AI research, and model training with inputs and outputs.

Plan Scope
Upstage free API tier under the May 2026 terms and August 2026 privacy policy; paid, promotional, async, console, and third-party models differ.
Prompt Retention
Free-service request and response data may be stored through the end of service provision or another separately notified period for delivery, improvement, and AI research. The general paid API rule is no storage except operationally necessary state.
Response Retention
Same free-tier policy; asynchronous results are stored for 30 days, while request data remains until completion.
Ordinary Logging
Service usage records, access logs, and IP addresses are retained for three months; account, transaction, and support records have longer statutory periods.
Model Training
Current terms expressly allow free-service input and output data to be used for AI research and development, including training. Paid API data is not trained on without separate consent.
Product Improvement
Free-tier input and output data may be used for service quality improvement and R&D. Paid API content requires separate consent for logging or improvement.
Human Or Operator Access
Stored free-tier data can be accessed for service delivery, improvement, research, safety, and legal compliance under Upstage and subprocessor controls.
Subprocessors And Routing
Some services use third-party AI providers whose policies govern content. Current privacy disclosures list Azure, OpenAI, Fireworks, and other overseas subprocessors with feature-specific retention.
Deletion Controls
Free data is destroyed when its stated retention or service-provision period ends; membership withdrawal deletes many account resources, subject to legal records. No free-tier immediate content-deletion control is documented.
Caveat
Older Upstage API terms said API data was not stored or trained on, but the current May 2026 terms create an explicit free-service exception. Do not apply the older no-training summary to today's free tier.
