            {"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("JetBrains/Qwen3.8-3.6-27B-blend")
model = AutoModelForMultimodalLM.from_pretrained("JetBrains/Qwen3.8-3.6-27B-blend", 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)

Modifications to upstream Qwen material

This distribution contains files modified by JetBrains from Qwen models developed by Alibaba Cloud. This document records the modifications and identifies the affected model files; it accompanies the binary artifacts listed below.

Base model merge

This model is a 50/50 combination of Qwen3.6-27B and Qwen3.8-27B, created by linearly interpolating their checkpoint parameters. The configuration, tokenizer, processor, and chat template are retained from Qwen3.8-27B. Exact source revisions and merge settings are recorded in merge-manifest.json.

The interpolation uses float32 accumulation. Upstream sources:

Qwen/Qwen3.6-27B, revision 6a9e13bd6fc8f0983b9b99948120bc37f49c13e9, weight 0.5.
Qwen/Qwen3.8-27B, revision 1d4bf0f2ff6012fd82039f2fa52739d0dd7c60c0, weight 0.5.

Distribution-specific changes

The merged parameters were saved as a sharded Safetensors checkpoint with a corresponding tensor index. Configuration, tokenizer, processor, and chat template were retained from the pinned Qwen3.8-27B source.

Modified model artifacts

The following files contain the merged parameters and, where applicable, the format conversions described above. SHA-256 values identify the binaries to which this modification notice applies.
