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

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("meta-llama/Llama-4-Scout-17B-16E-Instruct")
model = AutoModelForMultimodalLM.from_pretrained("meta-llama/Llama-4-Scout-17B-16E-Instruct", device_map="auto")

        ]
    },
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=256)

Are all of the differences in config.json between scout and maverick intended?

Specifically, scout has rope_scaling configured, use_qk_norm enabled, 10 times higher max_position_embeddings, only one interleaved_moe_layer_step and an empty array for no_rope_layers

~~At least the max_position_embeddings difference seems a bit suspicious, no?~~

Ups of course, for some reason in my mind I always thing maverick as the larger model has the longer context, even though that doesn't make much sense. The difference in rope scaling settings are due to the same thing then as well? I know people asking basic questions can be frustrating, but I'm just trying to eliminate as many things as possible because I can't get the model to run anywhere close to how it should be performing with default settings.

there's no problem at all about making basic questions. seems HF is the home of "taking as granted," i just wonder then why the platform says it's committed with education and democratization of AI, ML and NLP, if majority of answers, when any, are like that.
