What GPU do I need to run ponpoke/flux2-klein-9b-uncensored-text-encoder?
8.2B parameters, published in F16. View on Hugging FaceGated
Set up flux2-klein…red-text-encoderflux2-klein-9b-uncensored-text-encoder is published by ponpoke on Hugging Face, with 35,776 downloads and 496 likes to date. It's a Qwen3ForCausalLM model built for text-to-image, published natively in F16, and gated: you'll need to accept the model's terms on Hugging Face before downloading weights.
VRAM required & cheapest live GPU fit
Required VRAM = weight size at each precision, plus a fixed overhead for activation memory and allocator fragmentation. Diffusion and video models carry no KV-cache. The real driver of extra memory is output resolution and frame count, which this flat overhead does not model. Full formula and assumptions: methodology.
| Precision | Weight size | Required VRAM | Cheapest live fit | GPUs needed | Est. $/hr (full fit) |
|---|---|---|---|---|---|
| FP16 | 15.3 GB | 18.3 GB | RTX A5000 | 1 | $0.176/hr |
| FP8 (quantized) | 7.6 GB | 9.2 GB | RTX 5060 Ti | 1 | $0.110/hr |
| INT4 (quantized) | 3.8 GB | 4.6 GB | RTX 5060 Ti | 1 | $0.110/hr |
A GPU is only matched to a row if its hardware supports that precision, and the primary recommendation is always a single-GPU fit when one exists.
INT4 requires a quantized checkpoint actually published for this model, check its Hugging Face page before relying on this row.
Cheapest way to run flux2-klein-9b-uncensored-text-encoder at its published (F16) precision: 1× RTX A5000, at $0.176/hr per GPU ($0.176/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
flux2-klein-9b-uncensored-text-encoder: common questions
Does flux2-klein-9b-uncensored-text-encoder fit on a 24 GB GPU?
Yes. At FP16 it needs 18.3 GB of VRAM, so a 24 GB card holds it with 5.7 GB to spare. A 16 GB card is not enough for it at FP16.
Do I need approval to download flux2-klein-9b-uncensored-text-encoder?
Yes. ponpoke gates this repository on Hugging Face, so you have to accept its terms with a signed-in account before the weights will download. It does not change the 18.3 GB the model needs once you have them.
What is the least VRAM flux2-klein-9b-uncensored-text-encoder can run in?
4.6 GB, at INT4 (quantized), which fits a 6 GB card, against 18.3 GB at FP16. That row assumes an INT4 checkpoint has actually been published for this model, so check its Hugging Face page before planning around it.
Does quantizing flux2-klein-9b-uncensored-text-encoder lower the GPU bill?
Yes. At FP16 the cheapest live fit is one RTX A5000 at $0.176/hr. At FP8 (quantized) it drops to one RTX 5060 Ti at $0.110/hr, provided a quantized checkpoint exists for it.
