Introduction
Complete guide to using Flux Kontext API - In-Context Image Editing on PoYo
Flux Kontext API - In-Context Image Editing on PoYo
Access Flux Kontext API instantly on PoYo. Use Black Forest Labs' Kontext Pro and Max models for prompt-driven image generation, single-image editing, text replacement, and scene-aware transformations with `png` or `jpg` output.
Available Flux Kontext API Models on PoYo
02
Flux Kontext Pro Edit
`flux-kontext-pro-edit` adds single-image editing. `image_urls` is required, and the current PoYo API uses only `image_urls[0]`.
03
Flux Kontext Max
`flux-kontext-max` is the premium variant for stronger prompt adherence and text-heavy creative work.
04
Flux Kontext Max Edit
`flux-kontext-max-edit` is the highest-control edit path when you care more about text fidelity and output precision than raw speed.
Key Features of Flux Kontext API
Official Kontext models from Black Forest Labs for prompt-driven generation and single-image editing.
01
Edit Images While Keeping the Scene Coherent
Black Forest Labs presents FLUX.1 Kontext as an in-context image generation family that can extract and modify visual concepts from an input image while keeping the result coherent. That is the practical reason to use it for edits that must preserve perspective, lighting, and the original scene structure.
- Rewrite or restyle a scene without rebuilding it
- Keep perspective and lighting more stable
- Use one uploaded image as the edit anchor
02
Strong Text Replacement and Visual Cleanup
Flux Kontext is a good fit for signage, packaging, storefronts, and other design-heavy images because it can update text and local visual elements without redrawing the whole frame. This is the kind of search intent users often have when they look for Flux Kontext Pro or Max.
- Change signs, labels, and packaging text
- Swap local visual elements with simple prompts
- Keep nearby layout details closer to the source
03
Pick Pro for Speed or Max for Higher Fidelity
Black Forest Labs positions Pro as the stronger everyday balance for fast iteration, while Max is the premium path when prompt adherence and typography quality matter more. On PoYo you can keep the same request shape and switch only the model name.
- Use Pro for faster everyday workflows
- Use Max for stricter prompt and text fidelity
- Keep the same `size` and `output_format` API shape
Who Can Benefit from Flux Kontext API?
01
Storefront and Signage Updates
Replace storefront signs, menu text, poster text, or packaging copy while keeping the source image composition recognizable.
02
Product and Packaging Teams
Use Flux Kontext to update labels, colors, or scene styling around a hero product image without fully regenerating the shot.
03
Marketing and Social Content
Iterate on campaign visuals quickly by changing styling, text, props, or local design details from one approved source image.
04
Profile and Portrait Editing
Handle hairstyle, clothing, expression, or background changes when you want the edited image to keep more of the original identity cues.
Flux Kontext Pro vs Flux Kontext Max on PoYo
Use this table when your main question is whether Flux Kontext Pro is enough or whether Flux Kontext Max is worth the extra cost for text-heavy and precision-sensitive work.
| Feature | Flux Kontext Pro | Flux Kontext Max |
|---|---|---|
| Best For | Fast everyday generation and editing | Higher-fidelity prompt and typography work |
| Editing Support | Yes | Yes |
| Input Image Handling | Edit models require image_urls[0] | Edit models require image_urls[0] |
| Output Format | png or jpg | png or jpg |
| Aspect Ratios | 1:1, 4:3, 3:4, 16:9, 9:16, 21:9, 16:21 | 1:1, 4:3, 3:4, 16:9, 9:16, 21:9, 16:21 |

PoYo API docs state that Flux Kontext edit models require `image_urls`, and only the first image is used.
How to Use Flux Kontext API on PoYo
Step 1: Create your API key
Sign up on PoYo and create an API key for the standard async image workflow.
Create API Key →
Step 2: Choose Pro or Max
Select a generation or edit model, then set `size` and `output_format`. If you use an edit model, upload one source image because the API currently uses only `image_urls[0]`.
Add Credits →
Step 3: Submit and poll the task
Send the request to the unified submit endpoint, store the `task_id`, and poll the standard status API until the task is `finished`.

Flux Kontext API Pricing: Pro and Max Options
Flux Kontext Pro / Pro Edit: 8 credits per image ($0.04).
Flux Kontext Max / Max Edit: 16 credits per image ($0.08).
Both tiers support generation and editing through the same async workflow, with `png` or `jpg` output and the same supported aspect ratios.
Frequently Asked Questions about Flux Kontext API
Which Flux Kontext models are available on PoYo?
PoYo supports `flux-kontext-pro`, `flux-kontext-pro-edit`, `flux-kontext-max`, and `flux-kontext-max-edit`, so you can choose between lower-cost iteration and higher-cost, higher-fidelity output.
What parameters does Flux Kontext API support?
Flux Kontext supports `size`, `output_format`, and edit-mode `image_urls`. Supported sizes are `1:1`, `4:3`, `3:4`, `16:9`, `9:16`, `21:9`, and `16:21`. `output_format` supports `png` and `jpg`.
Can I upload multiple images for Flux Kontext editing?
The current PoYo docs say edit models require `image_urls`, but only `image_urls[0]` is used. In other words, you should upload one source image for reliable behavior.
When should I choose Pro vs Max?
Choose Pro when you want a lower-cost, faster model for day-to-day prompt iteration. Choose Max when your work is more sensitive to prompt adherence, typography quality, and higher-fidelity results.
Is Flux Kontext mainly for generation or for editing?
It is built for both. The model family covers prompt-only generation and single-image editing, which is why it is useful for teams that want to move between new asset creation and source-image revision without switching providers.
Why Use PoYo for Flux Kontext API Access
01
Instant Model Access
Start with Flux Kontext Pro or Max immediately from one PoYo account instead of managing another provider-specific setup flow.
02
Simple Async Integration
Flux Kontext uses the same PoYo submit-and-poll workflow as other image models, which keeps integration complexity low.
03
Clear Tiered Pricing
Keep costs predictable with direct Pro and Max pricing, then switch models only when a task really needs higher prompt or text fidelity.
04
One Key for Cross-Model Workflows
Use the same PoYo account for Flux Kontext, Seedream, GPT Image, Nano Banana, and video models when your product needs more than one creative backend.
