{"servers":[{"url":"https://api.modellix.ai/api/v1/google/imagen-4.0-ultra-generate-001"}],"post":{"description":"[Core Function] Imagen 4.0 Ultra is Google's premium text-to-image model optimized for the highest quality and instruction alignment. [Strengths] It delivers ultimate photorealistic detail, superior texture rendering, and extremely strict adherence to complex, multi-part prompt instructions, supporting up to 2K resolution. [Best For] Highly recommended for high-end commercial marketing assets, professional design, intricate artistic compositions, and scenarios where precise instruction-following is paramount. [Limitations] Do NOT use this model if you need instant/real-time generation, native image editing (inpainting/outpainting), or negative prompts. It is the most expensive tier in the Imagen family. [Routing] Choose this model when the user demands the absolute highest quality, ultimate detail, or has highly complex prompt instructions. Otherwise, default to standard Imagen 4.0 or Imagen 4.0 Fast.","operationId":"imagen40UltraGenerate001Async","requestBody":{"content":{"application/json":{"examples":{"portrait":{"summary":"Portrait with person generation","value":{"aspectRatio":"3:4","imageSize":"2K","personGeneration":"allow_adult","prompt":"Studio portrait of a professional businessperson, confident smile"}},"ultra_quality":{"summary":"Ultra quality generation","value":{"prompt":"Cinematic still from a sci-fi film, astronaut on alien planet, volumetric lighting"}}},"schema":{"properties":{"aspectRatio":{"default":"1:1","description":"Image aspect ratio","enum":["1:1","3:4","4:3","9:16","16:9"],"example":"16:9","type":"string"},"imageSize":{"description":"Output image resolution","enum":["1K","2K"],"example":"1K","type":"string"},"personGeneration":{"default":"allow_all","description":"Person generation policy","enum":["dont_allow","allow_adult","allow_all"],"example":"allow_all","type":"string"},"prompt":{"description":"Image description text","example":"A golden retriever playing fetch on the beach at sunset","minLength":1,"type":"string"},"sampleCount":{"default":1,"description":"Number of images to generate per request","example":1,"maximum":4,"minimum":1,"type":"integer"}},"required":["prompt"],"type":"object"}}},"required":true},"responses":{"200":{"content":{"application/json":{"example":{"code":0,"data":{"get_result":{"method":"GET","url":"https://api.modellix.ai/api/v1/tasks/task-mno345"},"model_id":"google/imagen-4.0-ultra-generate-001","status":"pending","task_id":"task-mno345"},"message":"success"},"schema":{"properties":{"code":{"description":"Response code, 0 indicates success","example":0,"type":"integer"},"data":{"description":"Detailed data about the submitted asynchronous task.","properties":{"get_result":{"description":"API information to query the task result","properties":{"method":{"description":"HTTP method","example":"GET","type":"string"},"url":{"description":"Full URL to query the task result","example":"https://api.modellix.ai/api/v1/tasks/task-abc123","type":"string"}},"type":"object"},"model_id":{"description":"Model ID in `provider/model` format","example":"google/nano-banana","type":"string"},"status":{"description":"Task status","enum":["pending","processing"],"example":"pending","type":"string"},"task_id":{"description":"Unique task identifier for polling","example":"task-abc123","type":"string"}},"required":["status","task_id","model_id"],"type":"object"},"message":{"description":"Response message","example":"success","type":"string"}},"required":["code","message","data"],"type":"object"}}},"description":"Task submitted successfully"},"400":{"content":{"application/json":{"example":{"code":400,"message":"Invalid parameters: parameter 'prompt' is required"},"schema":{"properties":{"code":{"description":"Error code (equals HTTP status code)","example":400,"type":"integer"},"message":{"description":"Error message in format 'Category: detail'","example":"Invalid parameters: parameter 'prompt' is required","type":"string"}},"required":["code","message"],"type":"object"}}},"description":"Invalid request parameters"},"401":{"content":{"application/json":{"example":{"code":401,"message":"Authentication failed: invalid API key"},"schema":{"properties":{"code":{"description":"Error code (equals HTTP status code)","example":400,"type":"integer"},"message":{"description":"Error message in format 'Category: detail'","example":"Invalid parameters: parameter 'prompt' is required","type":"string"}},"required":["code","message"],"type":"object"}}},"description":"Unauthorized -
