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

# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("SwissNeuron/Qwen3.8-27B-SwissNeuron-Derisked-FP8")
model = AutoModelForMultimodalLM.from_pretrained("SwissNeuron/Qwen3.8-27B-SwissNeuron-Derisked-FP8", device_map="auto")

            {"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=40)

Qwen3.8-27B-SwissNeuron-Derisked-FP8

FP8 dynamic quantization of SwissNeuron/Qwen3.8-27B-SwissNeuron-Derisked.

Source revision: repaired direct-answer SFT + fresh latest-SFT DWM α=0.1
Format: compressed-tensors W8A8 FP8 dynamic
Weight quantization: static FP8
Activation quantization: dynamic per-token FP8
Gated-DeltaNet linear-attention modules, vision tower, MTP draft head, embeddings, and LM head remain BF16 for compatibility and stability
Active config retains factor-4 YaRN to 1,048,576 tokens; validate extreme-context quality for your workload

Runtime

Use a current vLLM/Transformers stack with Qwen3.8 (Qwen3_5ForConditionalGeneration) and compressed-tensors support. FP8 compute requires recent NVIDIA GPUs; Hopper, Ada, and Blackwell are suitable.

vllm serve SwissNeuron/Qwen3.8-27B-SwissNeuron-Derisked-FP8 \
  --tensor-parallel-size 1 \
  --trust-remote-code

Thinking modes

The repaired checkpoint supports both modes through the included chat template:

tokenizer.apply_chat_template(messages, enable_thinking=True, add_generation_prompt=True)

Set enable_thinking=False for lower-latency direct answers.

Limitations

This is a quantized derivative. Re-evaluate critical workloads and long-context retrieval rather than assuming BF16 parity. The underlying model and release notes are documented in the source repository.
