{"servers":[{"url":"https://api.modellix.ai/api/v1/minimax/hailuo-2.3-fast-i2v"}],"post":{"description":"[Core Function] Hailuo 2.3 Fast I2V is a high-speed, cost-effective image-to-video generation model. [Strengths] It excels at generating videos from images much faster and at roughly 50% lower cost than the standard 2.3 model, while still maintaining the 2.3 architecture's strength in human motion. [Best For] Highly recommended for: rapid prototyping, batch social media creation, and cost-sensitive video generation pipelines. [Limitations] Do NOT use this model for text-to-video (it only accepts image inputs). Do NOT use when absolute maximum visual fidelity is the primary requirement. [Routing] Choose this model when the user emphasizes 'fast', 'quick', or 'cost-effective' image-to-video generation. For maximum quality, use the standard Hailuo 2.3 I2V.","operationId":"minimaxHailuo23FastI2VAsync","requestBody":{"content":{"application/json":{"examples":{"basic":{"summary":"Quick video generation","value":{"fast_pretreatment":true,"first_frame_image":"https://example.com/image.jpg","prompt":"Quick animation test"}}},"schema":{"properties":{"duration":{"default":6,"description":"Video duration in seconds","enum":[6,10],"example":6,"type":"integer"},"fast_pretreatment":{"default":false,"description":"Fast pretreatment mode (only effective when prompt_optimizer=true)","example":false,"type":"boolean"},"first_frame_image":{"description":"First frame image URL or Base64 Data URL","example":"https://example.com/image.jpg","minLength":1,"type":"string"},"prompt":{"description":"Video content description, supports camera control instructions","example":"Quick animation test","maxLength":2000,"minLength":1,"type":"string"},"prompt_optimizer":{"default":true,"description":"Enable automatic prompt optimization","example":true,"type":"boolean"},"resolution":{"default":"768P","description":"Video resolution","enum":["768P","1080P"],"example":"768P","type":"string"}},"required":["first_frame_image"],"type":"object"}}},"required":true},"responses":{"200":{"content":{"application/json":{"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","example":"model-123","type":"string"},"status":{"description":"Task status","enum":["pending","processing"],"example":"pending","type":"string"},"task_id":{"description":"Unique task identifier","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":{"examples":{"invalid_duration":{"summary":"Invalid duration value","value":{"code":400,"message":"Invalid parameters: duration must be one of [6, 10]"}},"invalid_image":{"summary":"Invalid image format or size","value":{"code":400,"message":"Invalid parameters: image size exceeds 20MB or format not supported"}},"invalid_resolution":{"summary":"Invalid resolution for duration","value":{"code":400,"message":"Invalid parameters: 10 seconds duration only supports 768P resolution"}},"missing_first_frame":{"summary":"Missing required first_frame_image","value":{"code":400,"message":"Invalid parameters: parameter 'first_frame_image' 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 'first_frame_image' 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 'first_frame_image' is required","type":"string"}},"required":["code","message"],"type":"object"}}},"description":"Unauthorized -
