How this was valued: The Lite plan's three independently documented monthly allowances are priced at IBM's current US rates. The 300K shared foundation-token pool is valued once against Granite 4H Small by assigning the envelope to costlier output tokens; other models and regional price differences are excluded.

This is a conservative subtotal because IBM's broader catalog uses model-specific token multipliers and regional prices.

What happens to your prompts?

PrivateReviewed

IBM says unsaved API prompts and outputs are not accessed, logged, stored, trained on, or used for improvement without permission.

Plan Scope
IBM watsonx.ai SaaS foundation-model inference; saved assets, prompt sessions, tuning data, and third-party models have additional state and terms.
Prompt Retention
IBM states it does not access, log, or store unsaved API prompts or outputs. Content deliberately saved as project assets is stored until the customer deletes it; temporary prompt-session assets can persist for 30 days.
Response Retention
Unsaved API outputs receive the same no-log and no-store treatment; saved results follow project and feature lifecycle controls.
Ordinary Logging
IBM retains account and service-usage metadata for operations, security, metering, support, and contractual obligations without treating unsaved prompt content as ordinary logs.
Model Training
IBM states customer prompts and outputs are not used to train foundation models or improve the service without permission.
Product Improvement
Unsaved prompts and outputs are excluded from service or model improvement; separately supplied feedback, tuning data, or expressly authorized data can be governed by their feature terms.
Human Or Operator Access
IBM says unsaved API prompts and outputs are not accessed. Saved assets and support cases can be accessed as needed under IBM Cloud security and contractual controls.
Subprocessors And Routing
IBM Cloud subprocessors and, where selected, third-party model providers may process data under the service terms and DPA; model-specific terms can add restrictions.
Deletion Controls
Customers can delete saved project assets; prompt-session assets expire after 30 days. Contract termination and personal-data rights follow IBM Cloud terms and privacy procedures.
Caveat
The strongest no-store statement applies to unsaved API requests. Prompt Lab history, projects, files, deployments, tuning data, support material, and third-party models can create separately retained state.
