License Library Merge Method

Architecture Experts Layers

A four-way MoE merge of the Qwen 35B-A3B architecture, fusing task vectors from three specialized fine-tunes into a base anchor via DARE-TIES with sinusoidal depth modulation.

Designed specifically to consolidate software engineering, code synthesis, and agentic tool execution capabilities. Multimodal vision weights and Multi-Token Prediction (MTP) heads were stripped to reduce VRAM footprint and maximize throughput during coding tasks.

Composition

Jackrong/Qwopus3.6-35B-A3B-Coder serves as the base anchor (W₀); the remaining three models contribute task vectors at the listed weights.

Model Role Task Weight (α)
Jackrong/Qwopus3.6-35B-A3B-Coder Base anchor (W₀) 1.00
ornith-ai/Ornith-1.5-35B-A3B Donor (D₁) 0.30
Kwaipilot/KAT-Coder-V2.5-Dev Donor (D₂) 0.25
Qwen/Qwen-AgentWorld-35B-A3B Donor (D₃) 0.20

Merge Methodology

For each floating-point parameter, a task delta is computed per donor kk:

Δk=DkW0 \Delta_k = D_k - W_0

DARE pruning. A Bernoulli mask at retention density pp zeroes out low-magnitude updates; surviving values are rescaled by p1p^{-1}:

Δ~k=1p(ΔkMk),MkBernoulli(p) \tilde{\Delta}_k = \frac{1}{p} \left(\Delta_k \odot M_k\right), \quad M_k \sim \text{Bernoulli}(p)

TIES sign election. A consensus sign Γ\Gamma is computed via weighted vote across donors, and any donor update conflicting with it is dropped before averaging:

Γ=sgn(k=1KαkΔ~k) \Gamma = \operatorname{sgn}\left(\sum_{k=1}^K \alpha_k \tilde{\Delta}_k\right)

ΔTIES=k=1KαkΔ~kI(sgn(Δ~k)=Γ)k=1KαkI(sgn(Δ~k)=Γ)+ϵ \Delta_{\text{TIES}} = \frac{\sum_{k=1}^K \alpha_k \tilde{\Delta}_k \odot \mathbb{I}\left(\operatorname{sgn}(\tilde{\Delta}_k) = \Gamma\right)}{\sum_{k=1}^K \alpha_k \cdot \mathbb{I}\left(\operatorname{sgn}(\tilde{\Delta}_k) = \Gamma\right) + \epsilon}

Depth-scaled reconstruction. The merged weight is reconstructed as:

Wfinal=W0+λ(l)ΔTIES W_{\text{final}} = W_0 + \lambda(l) \cdot \Delta_{\text{TIES}}

where the layer scaling factor λ(l)\lambda(l) across decoder layer index l[0,39]l \in [0, 39] is defined as:

λ(l)=β(0.5+0.5sin(πl39)) \lambda(l) = \beta \cdot \left(0.5 + 0.5 \sin\left(\pi \frac{l}{39}\right)\right)

This keeps input/output projections closer to the base and applies the strongest task transfer to middle layers (l[12,28])(l \in [12, 28]).

  • Router protection: Gate weights use linear interpolation (~57% base, ~43% donors) rather than DARE to avoid destabilizing expert routing.
  • DeltaNet stability: Recurrent state kernels are excluded from DARE to prevent divergence in the linear-attention state space.
  • MTP removed: Multi-token-prediction heads beyond the 40 primary decoder blocks were stripped for standard CausalLM inference.

Chat Template

This model uses the Improved Chat Template for Qwen 3.x by Olivia Rossi to support multi-tier Chain-of-Thought (CoT) reasoning, dual-format agentic tool execution, automatic error-recovery heuristics, and strict token-waste elimination.

Need fast GPU inference? Running a 35B MoE with CPU offloading or on under-provisioned consumer RAM can result in low token throughput. If you lack a local 24 GB+ GPU and want faster inference, you can spin up an hourly instance on RunPod in one click to run llama-server with 100% layer offload. New accounts created through the link below receive bonus compute credits ($5–$500 on your first $10 top-up).

Deploy on RunPod

Affiliate Disclosure: If you register an account and load funds using this link, I receive a small commission and platform credits from RunPod at no extra cost to you. These earnings are directly reinvested into renting GPU compute for ongoing open-source model merging, testing, and evaluation. Thank you for your support!


Recommended Generation Parameters

For code generation and agentic task trajectories, avoid high temperatures to maintain routing stability and syntax validity.

Parameter Coding / Terminal Agent Creative Reasoning
Temperature 0.6 1.0
Top-P 0.95 0.95
Min-P 0.0 0.01
Repetition Penalty off 1.05
