Logs and retention

Every request is logged with its input, output, credits and timing, and kept for a fixed period.

Every submission, including rejected ones, is visible under Settings → API Logs with its request id, input, output, credits and timing. The same data is available programmatically through GET /v1/generations.

What is stored

  • The request input with prompts truncated to 2,000 characters.
  • Inline data: images in your request are uploaded to our storage and the log stores the resulting URLs, not the base64 payload.
  • The output URLs, the credits charged, whether they were refunded, and how long the generation took.
  • The key that made the request, so a leaked key can be traced and revoked.

Retention

Completed and rejected request records become eligible for daily cleanup after 180 days. Pending generations and requests awaiting a billing review are retained until resolved. This cleanup removes request records; it does not delete generated files from your account library.
