            {"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("bespokelabs/Nimble-v4-max")
model = AutoModelForMultimodalLM.from_pretrained("bespokelabs/Nimble-v4-max", device_map="auto")
messages = [

            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
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)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Nimble-v4-max

Nimble-v4-max is a decision model made by Bespoke Labs, a fine-tune of Qwen/Qwen3.8-27B. Given a context and typed questions (a choice among options, a yes or no, or a score on ordered levels), it returns a probability for each option.

Decision Index 0.3, public suite: 68.46. The full run, the inference code and instructions are in bespokelabs/nimble-v4-max-decision-index.

How to run it

Use the inference code in bespokelabs/nimble-v4-max-decision-index (code/nimble/). It builds the prompts that schema_config.json pins by hash, reads each request with the attention pattern the model was trained with, and scores one token per option. Loading the weights as a plain chat model, or generating text, does not reproduce its answers.

The model needs about 55 GB in BF16, so it runs on one 80 GB or larger GPU.
