        ]
    },

        ]
    },
]
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)

Thanks for the interest. We’ve already started rebuilding it with the 3.6 architecture.

Have you taken a look at the APEX quantization option? I wonder if you could provide the darwin-qwen3.6 with an APEX option, as the model size is reduced significantly, but it retains most of its capabilities.

Thanks for the suggestion — great point!

Yes, we've been looking at APEX quantization for MoE
models, and since Darwin-35B-A3B-Opus is built on the
Qwen3.5 MoE architecture that APEX has been benchmarked
on (showing remarkable results — even beating F16
perplexity in some cases), it's a natural fit.

We're planning to release APEX variants in the following
tiers over the next 1-2 weeks:
• APEX Quality (21 GB) — maximum accuracy
• APEX Balanced (22 GB) — Q8_0 quality, smaller
• APEX I-Quality — diverse imatrix calibration
• APEX Mini (~12 GB) — consumer 16GB VRAM friendly

Will announce once uploaded. Thanks for bringing this
up — it's exactly the kind of feedback that helps us
prioritize community needs.

(Note: you mentioned "darwin-qwen3.6" — our current
Darwin MoE series is built on Qwen3.5-A3B; we'll note
this naming convention clearly in the APEX release.)
