GPT Image 1.5 API — Generation & Editing
The GPT Image 1.5 API hub brings text-to-image generation and instruction-based editing into one Muapi catalog. Choose low, medium, or high quality, use square or portrait/landscape outputs, and keep the same asynchronous request workflow for both endpoints.

$0.012–$0.432/imageWhat is the GPT Image 1.5 API?
GPT Image 1.5 is a two-endpoint image family on Muapi: gpt-image-1.5 generates images from prompts, while gpt-image-1.5-edit applies natural-language edits to one or more source images. Both endpoints share prompt, aspect-ratio, and quality controls.
The current schema supports 1:1, 2:3, and 3:2 outputs plus low, medium, and high quality. Generation accepts a required prompt; Edit requires a prompt and images_list with up to ten image URLs. Pricing varies by quality and aspect ratio: generation is $0.014–$0.300 per image and Edit is $0.012–$0.432 per image.
GPT Image 1.5 API capabilities
Complex prompt generation
Create coherent scenes, symbolic imagery, products, and cinematic concepts from detailed prompts.
Instruction-based editing
Change objects, backgrounds, lighting, or concepts while guiding the edit with natural-language instructions and source images.
Three aspect ratios
Choose 1:1, 2:3, or 3:2 for square, portrait, or landscape image outputs.
Quality-based pricing
Select low, medium, or high quality and pay according to the endpoint's verified quality and aspect-ratio cost strategy.
GPT Image 1.5 workflows
Concept and storyboard art
Generate complex scenes and imaginative worlds for storyboards, campaigns, and creative exploration.
Product and marketing variations
Use prompt generation for new product visuals and Edit for controlled background, lighting, or object changes.
Batch image editing
Pass up to ten source image URLs to the Edit endpoint when an instruction-driven workflow needs multiple references.
Quick start — GPT Image 1.5 API code examples
Submit a GPT Image 1.5 image task with your Muapi key, receive a request ID, and poll the shared predictions endpoint for the generated image URL.
1. Submit a GPT Image 1.5 job
curl -X POST https://api.muapi.ai/api/v1/gpt-image-1.5 \
-H "x-api-key: YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"prompt":"A glass observatory above a misty forest at sunrise","aspect_ratio":"16:9","quality":"medium"}'
# Response: {"request_id":"REQUEST_ID"}The example calls the generation endpoint with a prompt, aspect ratio, and medium quality. Switch to gpt-image-1.5-edit and include images_list for an edit.
2. Poll the result
curl https://api.muapi.ai/api/v1/predictions/REQUEST_ID/result \ -H "x-api-key: YOUR_API_KEY"
Poll until the task completes, then read the generated image URL from the result response.
GPT Image 1.5 API FAQ
Which GPT Image 1.5 endpoints are available?
Muapi lists gpt-image-1.5 for text-to-image generation and gpt-image-1.5-edit for instruction-based image editing.
What inputs does GPT Image 1.5 require?
Generation requires prompt. Edit requires prompt and images_list. Both endpoints accept aspect_ratio values of 1:1, 2:3, or 3:2 and quality values of low, medium, or high.
How many images can I provide to GPT Image 1.5 Edit?
The Edit schema accepts an images_list with up to ten image URLs. The prompt describes the requested transformation.
