Deepwen 3.6 (BF16)

Deepwen 3.6 is a fine-tuned derivative of Qwen/Qwen3.6-35B-A3B (MoE: 35B total / ~3B active), specialized for AAA GameDev 3D production workflows: procedural geometry, hard-surface shape language, and Blender/Unreal asset pipelines.

What the model has

  • Advanced thinking (DeepSeek style) — the model reasons before it answers. Its thinking comes from two sources:
    • Supervised reasoning training: the model was trained with full reasoning chains as part of the target, enabling deep analysis before responding.
    • Reasoning-effort control: a chat template ported from deepseek-ai/DeepSeek-V4-Flash-0731, with three effort levels — low (default), xhigh, and max ("Beyond maximum — exhaustive, relentless... do not stop reasoning until you have independently verified the solution from multiple angles").
  • Procedural 3D generation — explicit blockout gating before high-poly, conditional lightmap workflows, combinatorial validation, non-destructive pipelines.
  • Hard-surface shape language — stance/relational design, primary volume architecture, motif propagation, panel breakup.
  • Multi-skill asset workflows — Blender modifier-driven gear recipes, tooth profile generation, PBR game-prep, layered lighting legibility.
  • Design & UI expertise — modern interface design, layout systems, component architecture, visual hierarchy, accessibility, and production-ready UI patterns.

Improvements over the base model

Capability Improvement
Procedural generation blockout_gate: PARTIAL → PASS; conditional_lightmap: FAIL → PASS
Replay safety base competence suite 6/6 intact (no regressions)
Shape / hard-surface no catastrophic flips across held-out objects
Blender gear recipe modifier_workflow, tooth_profile_generation, game_prep_uv_pbr, non_destructive_order
Lighting layered lighting legibility (bounce and ambient)
Design & UI modern layout systems, component architecture, visual hierarchy, accessibility

Format

  • safetensors, bfloat16 (26 shards, ~67 GB)
  • Base dtype: bf16; Mamba SSM tensors in f32
  • Includes the full model (no MTP layers stripped at this level)

Usage

Standard transformers / vLLM / SGLang loading:

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("quimmedes/Deepwen-3.6-bf16", torch_dtype="bfloat16")
tok = AutoTokenizer.from_pretrained("quimmedes/Deepwen-3.6-bf16")

To enable advanced thinking at maximum effort:

{
  "messages": [{"role": "user", "content": "..."}],
  "chat_template_kwargs": {"reasoning_effort": "max"}
}

Quantized versions

GGUF quantizations with MoQ (mixed) tensor types are published in:

quimmedes/Deepwen-3.6 — levels Q2.5 (IQ2_XXS), Q3, Q4.5, Q5, Q6, Q8, all without MTP (733 tensors), plus vision mmproj (BF16/F16).
