Supply a scene description to create an illustration, product setting or visual concept. Its documented controls include image size, standard or hd quality, and watermark\_enabled; the response supplies image URLs that should all be saved. - [**Ailoot Ultra · Images** `POST /v1/images/generations` `cogview-4`](https://ailoot.ai/models/en/cogview-4/#method-0) About the model This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below. CogView 4 turns a written image brief into image outputs. Select cogview-4 in POST /v1/images/generations and supply prompt as a text string. The required inputs are model and prompt. Use the brief to describe the main subject, its placement, the surrounding scene and the visual treatment you want to evaluate. For a product setting, describe the object, the surface beneath it, the background and the direction of light. For an illustration, specify the characters or objects, the intended mood and the composition. If the image will sit beside a headline or product description, state where the composition should leave clear space. Review the result against those concrete requirements before using it in a layout. The CogView-specific size guidance lists 1024x1024, 768x1344, 864x1152, 1344x768, 1152x864, 1440x720 and 720x1440. Its custom-size guidance places each side between 512 and 2048 pixels, divisible by 16, with no more than 2^21 total pixels. Match the framing to the placement: a portrait illustration, a square product scene and a wide visual call for different compositions as well as different dimensions. quality accepts standard or hd, with standard documented as the CogView default. watermark\_enabled is a boolean with a documented default of true. An optional user\_id string identifies the end user and must contain 6 to 128 characters. Keep that identifier separate from the creative prompt. Changes to quality or size should accompany a clear intended use for the image, rather than replacing the description of what should appear. Generation returns a synchronous JSON response containing created and data. Each data\[\] item supplies a url. Download every returned image and keep the response with the brief and chosen settings; do not retain only the first item merely because a preview shows one image. The documented contract does not introduce a separate video-style job polling step for this image request. If the response is interrupted or incomplete, retain the original request information and received result before deciding whether a further creation request is appropriate. Ailoot stores these images as owned media assets and returns signed Ailoot links. Find the asset records through GET /v1/media/assets?family=image, following every next\_cursor. Read GET /v1/media/assets/{asset\_id} with each actual asset\_id to obtain its content\_url; read that same asset again if its signed link expires. **Ailoot Ultra · Images** `POST /v1/images/generations` `cogview-4` [`cogview-4`](https://ailoot.ai/models/en/#m=cogview-4&route=Ultra&caller=cogview-4&fmt=images) ZHIPU /`cogview-4` ### Overview CogView 4 is Zhipu's text-to-image model, available in Ailoot Ultra under the exact ID cogview-4.

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.
