How this was valued: Conservative face value of the separately documented recurring platform balance. The advertised 30M Model API tokens are excluded because public pages do not reconcile them with token-priced litAI calls.

The signed-in billing page is authoritative; do not add the 30M-token claim to the $15 balance without confirming whether they are independent.

Reset
Free platform balance is topped up to $15 on the first of each month and does not accumulate.
Caveat
Public pages do not fully reconcile the 30M-token promise with token-priced litAI calls and the separate $15 balance; the signed-in billing page is authoritative.

What happens to your prompts?

Partially privatePartial review

Model-API retention, training, publisher access, and plan-specific protections are not documented fully.

Plan Scope
Lightning AI platform and hosted Model APIs; model publishers and deployed applications can add separate terms.
Prompt Retention
No Model-API-specific content retention period was found in the public legal or product documentation.
Response Retention
not documented
Ordinary Logging
Platform account, use, diagnostic, and security information may be collected; content logging is not clearly separated.
Model Training
No plan-specific commitment excluding free Model API inputs and outputs from training was found.
Product Improvement
General platform information may be used to operate and improve services; the treatment of inference content is unclear.
Human Or Operator Access
Lightning and the publisher/operator of a model endpoint may technically process content; no universal operator-access limitation is published.
Subprocessors And Routing
Requests run on Lightning infrastructure and can target third-party-published models or apps, creating a separate publisher trust boundary.
Deletion Controls
General account/privacy rights exist, but no per-request content deletion or TTL was found.
Caveat
Security and general legal policies do not establish a uniform privacy contract for every community Model API.
