Generate photorealistic images from text descriptions using Pony models. Pony models are known for their vibrant, high-quality outputs with excellent prompt adherence. See available [schedulers](/image-generation/pony-models/scheduler) for Pony models. ## Request Make a `POST` request to the endpoint below with the required parameters. ```bash theme={null} POST https://modelslab.com/api/v6/images/text2img ``` ### Body ```json json theme={null} { "key": "your_api_key", "model_id": "pony-realism", "prompt": "ultra realistic close up portrait ((beautiful pale cyberpunk female with heavy black eyeliner)), blue eyes, shaved side haircut, hyper detail, cinematic lighting, magic neon, dark red city, Canon EOS R3, nikon, f/1.4, ISO 200, 1/160s, 8K, RAW, unedited, symmetrical balance, in-frame, 8K", "negative_prompt": "blurry, low quality, distorted, deformed", "width": "1024", "height": "1024", "samples": "1", "num_inference_steps": "31", "safety_checker": "no", "seed": null, "guidance_scale": 7.5, "scheduler": "DPMSolverMultistepScheduler", "use_karras_sigmas": "yes", "algorithm_type": "sde-dpmsolver++", "clip_skip": "2", "webhook": null, "track_id": null } ``` ## OpenAPI ````yaml image-generation/pony-models/openapi.json POST /text2img openapi: 3.1.0 info: title: ModelsLab Pony Models Image Generation API description: >- API for AI-driven image generation using Pony models, including text-to-image, image-to-image, and inpainting capabilities. license: name: MIT version: 6.0.0 servers: - url: https://modelslab.com/api/v6/images description: Pony Models Image Generation API v6 server security: [] paths: /text2img: post: summary: Text-to-Image description: Creates an image from a text prompt using a Pony model. requestBody: required: true content: application/json: schema: $ref: '#/components/schemas/TextToImageRequest' responses: '200': description: Text-to-image generation response content: application/json: schema: oneOf: - $ref: '#/components/schemas/ImageGenerationSuccessResponse' - $ref: '#/components/schemas/ImageGenerationProcessingResponse' - $ref: '#/components/schemas/ImageGenerationErrorResponse' '400': $ref: '#/components/responses/StandardErrorResponse' '401': $ref: '#/components/responses/StandardErrorResponse' '500': $ref: '#/components/responses/StandardErrorResponse' components: schemas: TextToImageRequest: type: object required: - key - model_id - prompt properties: key: type: string description: Your API Key used for request authorization. model_id: type: string description: >- The ID of the Pony model to be used.
