Black Forest Labs released the Flux 2 family in November 2025 and describes [pro] as top performance at an affordable price. Flux 2 Pro is the realism specialist on this platform — skin, light, material — and it accepts more reference images per call than any other model here. Hand Flux 2 Pro a prompt list and it renders the whole set in one pass.
One per line — each line is a separate prompt.
Drag & drop or click to upload — PNG / JPEG / WEBP / GIF, up to 10MB each.
Black Forest Labs split Flux 2 into variants with genuinely different jobs, and only one of them is built for volume at a sane cost. This page pins that one so every image in a run stays comparable.
The Flux 2 line runs from [max], strongest at editing consistency, instruction following and web grounding, through [flex], which exposes step and guidance controls for typography work, down to the open-weight [dev] and [klein], an Apache 2.0 distilled release from January 2026. Flux 2 Pro is Black Forest Labs' own balance point between production quality and price — what a hundred-row batch actually needs.
Independent reviews single out physical accuracy as the clearest edge Flux 2 Pro has: skin texture and pores, iris detail, individual hairs, believable depth of field. When a batch has to read as photography rather than illustration, Flux 2 Pro gets closest without a retouching pass afterwards.
In the Flux 1 generation, creating an image and editing one meant loading different checkpoints. Flux 2 unifies both in a single architecture, and Black Forest Labs says quality holds at the same level for generation and editing at 4MP. That matters in a batch: prompt-only rows and reference-driven rows leave Flux 2 Pro looking like one coherent set.
Everything below is read from the same generation configuration the batch form uses — credit cost per resolution tier, which tiers exist, how many aspect ratios Flux 2 Pro offers, the reference-image ceiling and the prompt length limit. Nothing here is typed by hand, so nothing here can go stale.
Switch the resolution tier on the form and the credit cost moves with it; this row always reflects the live configuration.
Flux 2 Pro rewards a run that starts from visual direction rather than from text, so the order of operations here is deliberately different from a prompt-only page.
Drop in the images that define the look — the product, the face, the lighting, the palette. Flux 2 Pro takes the largest reference stack of any model on BulkImagen, so you rarely have to pick which single reference matters most, and every row inherits the same direction.
One prompt per row, typed in or read out of a spreadsheet column. Flux 2 improved multi-part instruction following over the Flux 1 generation, so a row can carry framing, lens character and material notes together instead of being cut down to three keywords and hope.
Choose an aspect ratio and a resolution tier, read the credit total on the confirmation screen, and let Flux 2 Pro work. Finished images gather in one place; take the ZIP once the grid looks right, and send single rows back through with a tighter prompt if they missed.
Black Forest Labs points at product visualisation, brand-consistent asset production, virtual photography, marketing collateral and interface or poster work. Those are the jobs where realism plus a deep reference stack pays for a Flux 2 batch.
Stage a catalogue without booking a studio: one product, one lighting setup, a different scene per row. Flux 2 Pro's material rendering survives the tight crop a listing thumbnail forces, so a single Flux 2 run covers hero images and detail tiles from the same references.
Load the mood board once and let one Flux 2 batch carry that direction through every prompt in the list. What comes back is a set you can present as a campaign — same palette, same treatment, same person — rather than a folder of unrelated one-offs.
Casting, location, weather and time of day all become prompt text. Because Flux 2 Pro leans realistic by default — reviewers note it takes real effort to pull Flux 2 Pro away from photorealism — storyboard frames and virtual shoots come back looking shot rather than drawn.

Attach the references, paste the prompts, and let one Flux 2 batch render every frame from the same weights and the same visual direction. Keep the ones that land, take them down as a ZIP, and put the rest back through with a sharper prompt.
