Available in Ailoot inputs, outputs and options are listed for the selected method below. Riverflow 2.5 Pro is the Pro profile of Sourceful’s Riverflow 2.5 image generation and editing family, aimed at creative work where control and final image quality matter. A text brief can create a visual, while reference images supply the product, artwork or scene to edit. The family’s distinguishing approach plans several editing steps, reviews candidates and corrects them toward the requested result rather than treating the first image as the complete workflow. For a campaign image, prepare the product references and brand direction before describing the scene. Specify the product features that distinguish one SKU from another, the arrangement, lighting and space needed for copy. A useful brief can place three labelled products into one coherent composition while keeping their colours, sizes and visible identity distinct. For a single-product lifestyle scene, identify which reference provides the object and which supplies the mood or setting, then state what should be preserved during the transformation. Riverflow 2.5 adds a custom scoring rubric to its reasoning and review process. Describe the criteria that matter to the artifact: product identity, label readability, composition, scene plausibility or the amount of space for a headline. After editing steps, the reasoning model can assess candidates against that rubric and decide how to continue. A packaging-oriented result and an expressive campaign visual need different review priorities, so keep the generation instruction separate from the criteria used to judge it. Thinking effort controls how much iterative work and how strict a review the family applies before accepting an image. The 2.5 producer workflow ranges from low to xhigh: lower effort supports early exploration, while more effort is useful when the brief needs additional refinement. More internal review does not remove the need to inspect the finished asset. For a demanding product layout, make the important details and acceptance criteria explicit so extra editing work has a clear goal. Font Control accepts up to two custom font files and uses the supplied lettering, spacing and weight as guidance. Provide the exact words to render, the role of each text block and the corresponding font reference. A headline and a short supporting caption can use different fonts without leaving the typographic hierarchy implicit. Inspect the actual letters and numbers in the output, particularly where a package label or product name identifies the item, rather than treating a font reference as proof that every glyph is correct. The 2.5 family provides normal, solid-colour and transparent background output modes, including transparent PNG for compositing, with export options at 1K, 2K and up to 4K. Select the artifact for its placement: a cutout for assembly into another design, a controlled solid background for consistent product sets or a completed scene for a campaign. Prepare the output shape and text placement together so increasing delivery detail does not solve a composition that puts the main subject in the wrong place. Pro remains distinct from the Fast profile and from the earlier Riverflow 2.0 generation. The 2.5 family builds on 2.0’s multi-step foundation with deeper review control, custom judging and expanded background and export choices. A useful final review compares the image with the product references, rubric and typography, then changes the specific instruction or criterion responsible for a mismatch. Keep the selected image with its brief and references so the next edit can refine the same creative direction rather than losing its established identity. **Ailoot Ultra · Images** `POST /v1/images/generations` `sourceful/riverflow-v2.5-pro` [`sourceful/riverflow-v2.5-pro`](https://ailoot.ai/models/en/#m=sourceful%2Friverflow-v2.5-pro&route=Ultra&caller=sourceful%2Friverflow-v2.5-pro&fmt=images) Sourceful /`sourceful/riverflow-v2.5-pro` ### Overview Riverflow 2.5 Pro is Sourceful’s quality-focused image generation and editing profile for product and campaign creative.

The final charge is calculated from the cost recorded for the original generation. Measured output duration and forecast quantities are not the final billable quantity. Tariff references do not add request options. Supported parameters are listed for the selected method. Fast mode Not specified When fast mode is selected Flex mode Not specified When flex mode is selected Maximum reasoning effort Not specified When maximum reasoning effort uses the default adjustment #### Estimated rates for comparison #### Prices by configuration Match each charge to the conditions shown.
