Speeds are estimates for a single request — one conversation at a time — calculated from memory bandwidth, model size and quantisation. Real throughput varies with the inference runtime and its version. Figures published by hardware vendors measure many simultaneous requests and are much higher.

With 32B parameters, FLUX.2 lands in the range a serious desktop card can handle once the weights are compressed. 132 of the cards we track can run it.
At the low end, a RTX A4500 handles it — 20 GB, at Q3_K_M, for about 22.9 tokens per second.
At the other end, a B200 generates roughly 106 tokens per second on it, on the strength of 8,000 GB/s of memory bandwidth.
Where it came from
FLUX.2 was published by Black Forest Labs, in Germany, in November 2025. The organisation is categorised as industry.
It works in Image generation, and is recorded as doing image generation.
Because its weights were released, nothing about running it depends on a provider staying available — it is yours once downloaded.
Understanding the speeds
The median result is around 20.7 tokens per second; 103 cards produce text faster than most people read it.
Every weight participates in every token here, so bandwidth is the whole story: the ranking below is effectively a ranking of memory throughput.
Without the attention layout on record, the memory column is an approximation. It is close enough to choose hardware by, and least reliable at long context.
Step by step
How to choose a GPU for FLUX.2
The table above has already assessed every card we hold specifications for against this model. Getting to your answer takes six steps.
-
01
Read the memory figure first
The table lists every card that can hold FLUX.2 — around 16.3 GB at Q3_K_M. That figure, not the card's headline performance, is what decides whether it runs.
-
02
Match the context to your actual use
Longer conversations cost memory on top of what the weights need. Move the slider to your real working length before trusting any row for FLUX.2.
-
03
Decide how much compression you will accept
Compression is what makes FLUX.2 fit smaller cards, at some cost in accuracy — Q3_K_M on the smallest card that fits. A minimum quality removes the ones that go too far.
-
04
Rank by throughput rather than spec sheet
The speed ordering for FLUX.2 is effectively an ordering by memory bandwidth, which is why the B200 tops it at 106 tok/s.
-
05
Read the fit column last
A tight fit runs FLUX.2 but leaves nothing spare for a longer conversation; comfortable has headroom. If you expect to grow the context, buy for comfortable.
-
06
Open the card you have settled on
Each card page repeats this sweep for every model we hold. It answers what else the hardware is good for, beyond FLUX.2.
Answers
FLUX.2 — common questions
Why does the quantisation differ between cards for FLUX.2?
A larger card holds a more accurate copy. Across the cards that run FLUX.2, 5 compression levels are used; the floor control above pins it to one.
How accurate are these FLUX.2 speed estimates?
These are estimates with real error bars. The fastest result here, 64–169 tok/s on the B200, could reasonably land anywhere in its published range depending on which runtime you use.
What GPU do I need to run FLUX.2?
The smallest card in our catalogue that holds FLUX.2 is the RTX A4500, with 20 GB of memory. It runs the model at Q3_K_M using about 16.3 GB, and produces roughly 22.9 tokens per second. 132 cards in total can run it.
How fast is FLUX.2 on a GPU?
It depends on the card. The quickest we calculate is a B200 at about 106 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 103 of the cards that can run FLUX.2 clear that.
How much VRAM does FLUX.2 need?
About 16.3 GB at Q3_K_M compression, which is what the smallest card that runs it uses. Less compression needs more: the figures in the memory column above are recalculated for each card, because each one holds the least-compressed version it can.
Can I run FLUX.2 on a 24 GB GPU?
Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q4_K_M, using about 20.1 GB and generating roughly 40.9 tokens per second — a tight fit.
Is FLUX.2 open source?
Its weights are published, so FLUX.2 can be downloaded and run on your own hardware. Note that open weights is not the same as open source in the full sense — it says nothing about the training data, the training code, or the commercial terms attached.
How many parameters does FLUX.2 have?
FLUX.2 has 32B parameters. "32B parameter flow matching transformer" (https://github.com/black-forest-labs/flux2, README; https://bfl.ai/blog/flux-2). That figure is the total, and it is what decides how much memory the model needs — roughly half a gigabyte per billion at the compression most people use.
Who created FLUX.2?
FLUX.2 was published by Black Forest Labs, based in Germany, categorised as industry.
When was FLUX.2 released?
FLUX.2 was published in November 2025.
What is FLUX.2 used for?
FLUX.2 works in Image generation, and is recorded as handling image generation. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.
Where can I download FLUX.2?
The weights for FLUX.2 are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.
Can I run FLUX.2 if it does not fit in my GPU?
Partly. Layers that do not fit sit in system memory and run at a fraction of the speed, so a mostly-offloaded FLUX.2 is rarely worth using — the nearest miss we calculate is short by 5.7 GB. Every figure here assumes the whole model is on the card.
Would two GPUs run FLUX.2 faster?
Two cards buy memory rather than speed. That matters for FLUX.2 only if one card cannot hold it — 132 can, so a second adds little.
The other direction
Looking at it from the other side?
This page starts from the model. If you already own a card and want to know everything it will run, start from the hardware instead.
