Flux 2 Pro Image-to-Image vs FLUX Erase: Which Flux Editor for Which Edit

Flux 2 Pro Image-to-Image and FLUX Erase are both Black Forest Labs editors on VdoBloom, but they take opposite inputs: Flux 2 Pro takes a written instruction across one to eight images and costs 12 credits per run, while FLUX Erase takes no prompt at all — you paint over what you want gone and it costs 10 credits. If the edit can be described in a sentence, Flux 2 Pro is the right tool. If the edit is best described by pointing at a region, FLUX Erase is.

The one difference that decides everything

Most model comparisons come down to quality and price. This one does not. Flux 2 Pro Image-to-Image is an instruction editor: you upload source material, write what you want changed, and the model re-renders the frame according to that description. FLUX Erase is a mask-driven inpainter with no prompt field whatsoever. Its job is narrow and mechanical — remove the pixels you marked and reconstruct the area behind them from surrounding context.

That means the two models fail in different ways, which is more useful to know than which one scores higher. Flux 2 Pro can misread an instruction and change something you did not want touched. FLUX Erase cannot misread anything, because there is nothing to read — but it also cannot add. Ask it to replace a logo with a different logo and you will get a blank wall where the logo was, because replacement is not in its vocabulary.

Flux 2 Pro Image-to-Image: the describable edit

Flux 2 Pro accepts one to eight input images in a single job. That multi-image ceiling is the feature people underuse. Feeding several related frames lets the model draw on a shared subject or a consistent style across the set rather than treating each edit as an isolated guess.

It offers eight framing options — 4:3 (the default), 1:1, 3:4, 16:9, 9:16, 3:2, 2:3, and an auto mode. Auto is the one that matters for corrective work: instead of forcing your result into a preset frame, it matches the output to the source dimensions, so a targeted edit does not come back silently cropped or padded. Output resolution is 1K or 2K, and prompts can run from 3 to 5,000 characters.

The model carries a MODERATE content label on VdoBloom and a 4.1 community rating. Full spec detail lives on the Flux 2 Pro Image-to-Image model page.

FLUX Erase: the pointable edit

FLUX Erase is the cleanest object-removal path on the platform because it removes the language step entirely. In the image editor, selecting FLUX Erase changes the upload panel: you upload one source image, then a brush appears directly over it. You paint the areas you want erased, and the painted region becomes the mask that goes to the model. White means erase. There is no prompt box to fill in and no instruction to get wrong.

Under the hood the model is bfl:flux@erase, and it requires both the source and the mask — which is why the generate button stays disabled until the painted mask exists. It is rated 4.2 on VdoBloom and also carries a MODERATE content label.

Specs and credit cost side by side

New accounts get 10 free credits with no card, so a single FLUX Erase run fits inside the free allowance. Credit pricing below uses the Lite plan rate of $15 for 300 credits, which makes one credit $0.05.

Which one for which job

Remove a person, a sign, a cable, a watermark-shaped blob, a stray hand. FLUX Erase, every time. Two credits cheaper and structurally incapable of drifting into an area you did not select.

Change a colour, a material, a garment, a background mood. Flux 2 Pro. These are additive edits and need a prompt to define the target state.

Keep a subject consistent across several images. Flux 2 Pro, using its eight-image input. This is also why it appears in the pose variations tool, where consistency across a set is the entire point.

Deliver a 2K hero asset. Flux 2 Pro, at the 2K resolution tier. FLUX Erase has no resolution control — it works at whatever your source is.

Erase something, then fill the hole with something new. Both, in sequence. Erase first for a clean plate, then run that output through Flux 2 Pro with an instruction describing what belongs there. Two runs, 22 credits, $1.10 — and far more reliable than asking one model to do both at once.

A worked example

Say you have a product shot on a marble counter with a competitor’s bottle in the background and lighting that reads too cool.

Step one: open the editor, pick FLUX Erase, upload the shot, and paint over the background bottle. The mask goes to the model, the bottle disappears, and the counter and wall behind it are reconstructed. 10 credits.

Step two: switch to Flux 2 Pro, load the erased result, set aspect ratio to auto so the framing survives, set resolution to 2K, and prompt for warmer light and a softer shadow under the product. 12 credits.

Total: 22 credits, $1.10, two deterministic steps. The alternative — one Flux 2 Pro prompt asking for both the removal and the relight — costs 12 credits but will usually need two or three attempts, at which point it is the more expensive path and a less clean one.

When to pick neither

If your edit needs legible rendered text inside the image, Flux Kontext Max is the stronger member of the Flux family for typography and instruction adherence, at 10 credits. If you are starting from nothing rather than editing an existing frame, you want a generator instead — the image generation tab carries the text-to-image lineup. And if you need to extend a photo past its original borders rather than fix something inside it, FLUX Outpainting is the sibling model built for that, at 12 credits.

Whichever you pick, the credit cost for the run is shown before you generate, and one-time credit packs start at $2.49 for 75 credits that never expire — details on the pricing page. Paid plans also download watermark-free with commercial rights. When you upload a photo containing a real person, you need that person’s consent before editing it; the editor asks you to confirm this before it will run.

Frequently asked questions

Does FLUX Erase accept a prompt?

No. It is purely mask-driven. The service ignores any prompt text and reconstructs the painted region from surrounding image context alone. That is a design decision, not a limitation to work around — it is what makes the model predictable.

Is Flux 2 Pro Image-to-Image worth 2 more credits than FLUX Erase?

For removals, no — FLUX Erase does that job better and cheaper. For anything that adds, changes, or restyles content, Flux 2 Pro is the only one of the two that can do it at all, so the 12-credit cost is not really a premium over 10, it is a different product.

How many images can Flux 2 Pro edit at once?

Between one and eight per job. FLUX Erase takes exactly one source image plus the mask you paint on it.

Will FLUX Erase change the resolution or framing of my photo?

No. It works on the source you give it and returns the same frame with the masked region reconstructed. If you want a specific output size or ratio, that is a Flux 2 Pro job, where you choose 1K or 2K and one of eight aspect ratios including auto.

Can I use these on the free tier?

Yes. New accounts get 10 free credits with no card, which covers one FLUX Erase run. Flux 2 Pro at 12 credits needs a top-up — packs start at $2.49 for 75 credits and never expire.
