What was claimed
Qwen-Image-2.1 can now run locally on 12GB VRAM [...] The 7B model performs on par with Nano Banana 2.0. For higher quality, Dynamic FP8 on just 6GB VRAM
Our verdict
InaccurateThe vLLM recipe shows FP8 peak memory in the tens of GB, not 6GB. Other sources also place practical FP8 or FP16 usage far above 6GB, so this statement is not supported. This comparison appears in an Unsloth social post, but the provided sources do not include an independent benchmark or methodology. A separate article gives score comparisons, but it is not the same as proving “on par” in a rigorous sense. (Only 1 of 3 AI systems responded.)
