faq · straight answers
Can FLUX.1 dev run on 2x RTX 3090 (48GB)?
FLUX.1 dev needs 10GB+ and exceeds 2x RTX 3090 (48GB). Try a smaller quant or model. Model context 0k. Compare with all models or re-check with your exact specs on the bench.
What if it OOMs?
Unload with ollama stop, cap layers --num-gpu 28, cut context to 2k. See the OOM fixer on the homepage.
Q4 or Q8 on this rig?
Start Q4. Bigger model at Q4 beats smaller at Q8. Only go Q8 if 2GB+ headroom remains.
How fast will it be?
Slower than GPU — this combo needs offload. Pick a smaller model for interactive chat.
Is Non-commercial commercial-safe?
Non-commercial — check terms before commercial use. Filter commercial-safe on the bench.
