Affordable Flux Kontext API — AI Image Editing with Context Awareness

Flux Kontext is Black Forest Labs' context-aware image generation and editing family. Describe an edit in natural language and the model preserves the image's subject, lighting, proportions, and style unless you ask it to change them.Muapi exposes Dev, Pro, Max, and Effects variants through one asynchronous REST contract, covering both text-to-image and image-to-image workflows.

What is Flux Kontext?

Flux Kontext is Black Forest Labs' context-aware image generation and editing family. Instead of treating an input as isolated pixels, it reads the full semantic context before applying a change, helping objects stay proportional, lighting remain consistent, and the original style survive unless explicitly changed.

The family supports both image-to-image and text-to-image workflows across Dev, Pro, and Max tiers, plus the Effects variant for stylistic transformations. All variants use Muapi's asynchronous submit-and-poll API.

Key Features

Context-aware editing

Understand the full semantics of an image before making changes, keeping edits coherent, proportionate, and lighting-consistent.

Dev, Pro, and Max tiers

Choose open-weight experimentation, production speed and quality, or maximum fidelity for professional image work.

Text-to-image and image-to-image

Generate fresh images from prompts or edit existing images with natural-language instructions across the family.

Effects variant

Transform photos into cinematic, artistic, and creative styles with a single text description.

Natural-language instructions

Describe the desired change without masks, selection tools, or a large set of editing parameters.

One REST integration

Use the same Muapi authentication, task lifecycle, billing, and result polling for every Kontext variant.

Flux Kontext use cases

Product photo editing

Change backgrounds, lighting, materials, or small product details while preserving the original composition.

Creative content generation

Move from a rough prompt to polished campaign imagery with a tier matched to the required quality and speed.

Brand asset creation

Create consistent variations for ads, social posts, and ecommerce catalogs from a shared visual direction.

Photography enhancement

Retouch or relight a photo using plain language while keeping the subject and scene structure intact.

Style transfer and effects

Apply a defined cinematic, illustrative, or artistic treatment through the Effects variant.

Quick Start — Flux Kontext API Code Examples

Submit a prompt and, for image editing, an image URL. Muapi returns a request ID immediately; poll the standard prediction result endpoint for the output URL.

Image-to-image edit

curl -X POST https://api.muapi.ai/api/v1/flux-kontext-pro-i2i \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"Make the sky dramatic and stormy", "image_url":"https://example.com/photo.jpg"}'

# Response: {"request_id":"REQUEST_ID"}
curl https://api.muapi.ai/api/v1/predictions/REQUEST_ID/result \
  -H "x-api-key: YOUR_API_KEY"

Use a Kontext i2i endpoint when you want to preserve an existing image and apply a natural-language instruction.

Text-to-image generation

curl -X POST https://api.muapi.ai/api/v1/flux-kontext-pro-t2i \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"A futuristic city at sunset, ultra detailed, cinematic lighting"}'

# Response: {"request_id":"REQUEST_ID"}
curl https://api.muapi.ai/api/v1/predictions/REQUEST_ID/result \
  -H "x-api-key: YOUR_API_KEY"

Use a Kontext t2i endpoint to create a new image from a prompt without an input image.

Frequently Asked Questions

What is Flux Kontext?

Flux Kontext is Black Forest Labs' context-aware image generation and editing model family. It understands the full context of an image and edits, transforms, or regenerates it from natural-language instructions.

What is the difference between Flux Kontext Dev, Pro, and Max?

Dev is the open-weight option for research and low-cost experimentation. Pro offers higher quality and faster generation for production. Max delivers the highest fidelity and prompt adherence for professional image work.

What is Flux Kontext image-to-image versus text-to-image?

Image-to-image takes an existing image and an edit instruction, then returns a modified version. Text-to-image generates a new image from a prompt alone.

What is Flux Kontext Effects?

Effects is a stylistic variant for cinematic, artistic, and creative transformations. Describe the target visual style and Muapi returns a transformed image.

How do I get a Flux Kontext API key?

Create a Muapi account, generate an API key, and call the flux-kontext-dev-i2i, flux-kontext-pro-i2i, or flux-kontext-max-i2i endpoints. The same key works across the family.
