            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("aaronday3/gemma-4-31B-it-FP8-Dynamic")
model = AutoModelForMultimodalLM.from_pretrained("aaronday3/gemma-4-31B-it-FP8-Dynamic", device_map="auto")

            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },

	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)

gemma-4-31B-it-FP8-Dynamic

Dynamic FP8 quant of google/gemma-4-31B-it, produced with llm-compressor using the FP8_DYNAMIC scheme (per-tensor FP8 weights + dynamic per-token FP8 activations, no calibration data). Format is compressed-tensors (float-quantized), loadable natively by vLLM.

~33 GB on disk (vs ~62 GB bf16) -> fits a single 48 GB GPU. FP8 compute needs sm_89+ (Ada/Hopper): an L40S works, but an Ampere A6000 cannot run fp8 kernels.
Only the text decoder Linear layers are quantized. The vision tower and lm_head are kept in bf16 (small, precision-sensitive), so multimodal + output quality are preserved.
Self-quant so the provenance is trusted, and future serves skip the 62 GB pull + on-the-fly quant.

Serve with vLLM

vllm serve aaronday3/gemma-4-31B-it-FP8-Dynamic \
  --max-model-len 8192 --gpu-memory-utilization 0.90 --host 0.0.0.0 --port 8000
