Everything you need to know about credits, safety boundaries, and how the zengen-ai platform works.

Credit Wallet System

zengen-ai uses an internal credit wallet to manage access to AI operations. Every account starts with 10 free credits. Credits are consumed when you successfully complete an AI operation. Failed operations due to server errors do not consume credits.

Important: Credits are consumed at the time of a successful operation. If you cancel your subscription, you keep any remaining credits until they are exhausted. Credits do not roll over between billing periods on Pro and Studio Max plans.

The Detect & Erase Pipeline

Step 1: Credit Check

Before any AI call is made, the system verifies you have at least 1 credit. If you have insufficient credits, the request is rejected immediately with a 403 error — no AI calls are made.

Step 2: Segmentation Masking (Fal.ai)

Your image and text instruction are sent to our segmentation provider (Fal.ai). The AI identifies and isolates the described object, producing a precise binary black-and-white mask image.

Step 3: LaMa Inpainting (Replicate)

The original image and the binary mask are submitted to the Replicate LaMa (Large Mask inpainting) model. LaMa fills the masked region with seamlessly generated background content.

Step 4: Credit Deduction & Logging

Exactly 1 credit is deducted from your wallet. The generation is logged in our database including your prompt, mask URL, output URL, and moderation status.

Safety Boundaries & Moderation

zengen-ai employs a layered moderation system to ensure the platform is used responsibly. All generations pass through the following checks:

Automatic Content Detection

Prompts are scanned for mature content keywords before processing. If mature content is detected and the user has Unfiltered Mode disabled (the default), the generation is automatically flagged as pending_review in the admin panel. Users with Pro or Studio Max subscriptions may enable Unfiltered Mode, which passes enable_safety_checker: false to supported open-weight endpoints.

Admin Moderation States

approved

Default state. Content passed all safety checks and is publicly viewable.

pending_review

Flagged for admin review due to mature content keywords or NSFW mode being enabled.

blocked

Content was reviewed and blocked. The output image is replaced with a placeholder. The account is flagged.

Prohibited Content

The following content is strictly prohibited on the zengen-ai platform, regardless of subscription tier:

  • Sexual content involving minors (CSAM) — zero tolerance, immediate account termination and reporting to authorities
  • Non-consensual imagery of real, identifiable individuals
  • Content designed to harass, threaten, or defame specific individuals
  • Illegal content under applicable law (hate speech, incitement to violence)
  • Deepfakes of public figures for misinformation purposes

Enforcement: Accounts found to be generating prohibited content will be immediately suspended. Credits are non-refundable in cases of policy violation. Repeated violations may result in permanent bans and reporting to relevant authorities.
