Detailed scores

Credit model 4.5

Method: inferred · Scored:

Pay-per-generation pricing at $0.003 per 512x512 image is cited in notes, but no public pricing page was found among provided URLs, so unit costs are not independently verifiable.

Censorship transparency 2.5

Method: observed · Scored: · Source

ToS require users be 18+ and list prohibited activities, yet the platform hosts NSFW-oriented checkpoints like Babes and Realistic Vision without any explicit content policy reconciling this in the visible terms.

Persistence 2.0

Method: inferred · Scored:

Neither the ToS nor the privacy notice excerpt describes conversation history, generation history storage, or user-controllable memory settings for this API hosting service.

Data retention 4.0

Method: observed · Scored: · Source

The privacy notice has a dedicated 'HOW LONG DO WE KEEP YOUR INFORMATION' section title but the provided text cuts off before stating any concrete retention duration or deletion-on-request process.

Exit terms 2.5

Method: observed · Scored: · Source

Section 13 'TERM AND TERMINATION' exists in the ToS table of contents, but no visible clause specifies online cancellation, refund policy, or data export options for users.

Pros

  • Pay-per-generation pricing model, cited at roughly $0.003 per 512x512 image, allows granular cost control for API users
  • A privacy notice includes a dedicated section addressing how long user information is retained, indicating at least a documented intent to address data retention
  • Access to multiple Stable Diffusion checkpoints (SD1.5, SDXL) and I2V video generation gives developers flexibility in model choice
  • A 99.9% reliability SLA is advertised alongside low-cost GPU infrastructure, aimed at consistent service uptime

Cons

  • The ToS impose an 18+ requirement and prohibited-activity rules but do not clearly reconcile this with the platform hosting NSFW-oriented checkpoints like Babes and Realistic Vision
  • No description of conversation or generation history storage, nor of user-controllable memory settings, was found in the reviewed materials
  • The ToS reference a 'TERM AND TERMINATION' section in the table of contents, but no visible clause specifies cancellation steps, refunds, or data export options
  • The privacy notice's retention section is incomplete in the reviewed text, cutting off before stating a concrete retention duration or deletion process
  • No public pricing page was found to independently verify the cited pay-per-generation unit costs

Review

Sink In is a Stable Diffusion API hosting platform that gives developers access to multiple model checkpoints, including SD1.5 and SDXL, for programmatic image generation at 512x512 resolution. The service also offers video generation models via image-to-video (I2V) functionality, positioning it as an infrastructure layer for building applications on top of Stable Diffusion rather than a consumer-facing chat or art tool. Access is provided through pay-per-generation pricing, cited in notes at approximately $0.003 per 512x512 image, though no public pricing page was found among the reviewed sources to independently confirm current unit costs. The entry price is listed at $0.00, consistent with a freemium structure where users pay only for the generations they run. The platform advertises a 99.9% reliability SLA and low-cost GPU infrastructure as core selling points for developers who need consistent uptime. Beyond features and pricing, the available documentation leaves several operational questions open: the privacy notice includes a section titled on data retention duration, but the provided text cuts off before specifying an actual retention period or a deletion-on-request process. Similarly, the Terms of Service reference a termination section in their table of contents, yet no visible clause details cancellation steps, refunds, or data export options. The ToS also require users to be 18 or older and list prohibited activities, but the platform simultaneously hosts NSFW-oriented checkpoints such as Babes and Realistic Vision without a clear content policy reconciling this in the visible terms. There is no description in the reviewed materials of conversation or generation history storage, nor of any user-controllable memory settings.

Verdict: Sink In offers a functional API hosting service for Stable Diffusion image and video generation with a pay-as-you-go pricing model starting at $0.00 entry cost. However, gaps in publicly visible documentation around data retention specifics, termination and refund terms, and content policy reconciliation with hosted NSFW checkpoints leave several user-facing questions unanswered.
