Why This Model
Claude 4.7 Opus intelligence distilled into a locally runnable MoE, with abliteration for unrestricted research use:
- 256 experts, 3B active — extreme sparsity = extreme speed
- Claude 4.7 Opus distillation — latest Opus reasoning quality
- 262K native context — fits on single 96 GB GPU with FP8 KV
- VLM — vision fully functional (BF16 precision)
- Abliterated — no refusals, full capability for research and local deployment

Quantization Details
Recipe
recipe = QuantizationModifier(
targets="Linear",
scheme="NVFP4",
ignore=["lm_head", "re:.*visual.*", "re:.*mlp.gate$", "re:.*mlp.shared_expert_gate$"],
)
Calibration
- Dataset: HuggingFaceH4/ultrachat_200k (train_sft split)
- Samples: 512
- Max sequence length: 2048
moe_calibrate_all_experts=True— ensures all 256 experts receive calibration data

Requirements
- GPU: NVIDIA Blackwell (SM 120) — RTX 5090, 5080, 5070 Ti, RTX PRO 6000
- VRAM: ~22 GB minimum (text only), 96 GB for 256K context
- Software: vLLM nightly (cu130)
Notes
- Abliterated (uncensored). Use responsibly.
- Multimodal (vision) fully functional at BF16 precision.
- Gated DeltaNet + Attention hybrid architecture.
- NVFP4 is Blackwell-specific. Will not work on Ampere/Hopper.
- Use
--kv-cache-dtype fp8for 2x KV capacity at no quality cost.
