Flux 1.1 Pro vs Flux 2 Pro
Generated on PixelDojo. Produced by PixelDojo's generation pipeline.
Flux 1.1 Pro costs 1 credit per image and returned our landscape test in about 18 seconds. Flux 2 Pro costs 1.5 credits at its 1 megapixel default and took about 29 seconds on the same prompt. Flux 1.1 Pro is the cheaper, faster text-to-image option. Flux 2 Pro costs more but is the only one of the two that can edit an existing image from a reference. We sent the same storm-light rice valley prompt to both on August 26, 2026 and kept the first result from each.

Price, speed, and what each one actually rendered
Price
Flux 1.1 Pro is a flat 1 credit per image. Flux 2 Pro is 1.5 credits at its 1 megapixel default, but drops to 1 credit at its 0.5 megapixel tier, which matches Flux 1.1 Pro's price at a smaller size.
Measured speed
Flux 1.1 Pro finished in about 18 seconds. Flux 2 Pro took about 29 seconds on the identical prompt, roughly 60 percent longer. Both numbers move with queue load.
Only one of them edits an existing image
Flux 2 Pro accepts up to 10 reference image URLs alongside the prompt for multi-image editing, restyling, or compositing. Flux 1.1 Pro is text-to-image only and has no reference-image input at all. If the job starts from a photo you already have, Flux 1.1 Pro is not an option.
What Flux 1.1 Pro's output looked like
A wide establishing shot: terraced rice fields dropping away into a misty valley, dramatic storm clouds with sunbeams breaking through, and a hiker in a red jacket rendered small and distant on a ridge trail in the upper right of the frame. The scale read as epic but the hiker himself carried little detail.
What Flux 2 Pro's output looked like
The same storm light and sunbeams, but the hiker sat much closer in frame: visible hiking pole, backpack, and a red rain jacket with the hood up, walking directly along a flooded terrace edge with the water reflecting the sky. A small village was visible in the distance. The extra proximity gave the shot more usable subject detail for the same brief.
Resolution control
Flux 2 Pro exposes four resolution tiers, 0.5 through 4 megapixels, each priced separately. Flux 1.1 Pro has no separate resolution setting; output size follows the aspect ratio you pick from its 9 presets.
One prompt, two Flux tiers, same day. Flux 1.1 Pro: 1 credit, about 18 seconds. Flux 2 Pro: 1.5 credits, about 29 seconds.
How It Works
How we ran the comparison, so you can repeat it:
Send the identical prompt to both
We used the same storm-light rice valley prompt, word for word, on Flux 1.1 Pro and Flux 2 Pro at their default settings, on August 26, 2026.
Keep the first result from each
No retries, no reroll. Flux 1.1 Pro returned in about 18 seconds for 1 credit. Flux 2 Pro returned in about 29 seconds for 1.5 credits.
Decide on editing, not just price
If the job only ever starts from a text prompt, Flux 1.1 Pro is cheaper and faster. If it needs to work from a reference photo, Flux 2 Pro is the only one that can.
