- Base Architecture:
Qwen3_5MoeForConditionalGeneration(40 layers, 256 fine-grained micro-experts with intermediate dimension 512, 8 active per token) + Vision Projector. - Active Parameters: approx. 3.2B active parameters per token.
🔬 Comparative Quantization Analysis (vs. Flat Quants & Generic APEX)
Also, don't confuse APEX-I-MiniPlus-V2 with a generic baseline APEX-I-Mini. Traditional APEX-I-Mini drops core experts aggressively to 2-bit IQ2_S and leaves output.weight at 3-bit Q3_K_M, which creates a noticeable perplexity hit on complex reasoning tasks. V2 was specifically re-engineered to avoid that quality floor (keeping core experts at calibrated IQ3_XXS, output in Q6_K, shared expert in non-linear IQ4_NL, and routers in F32).
To put the numbers in perspective: this cuts nearly 2 GB off a flat 3-bit quant (approx. 15.6 GB), and weighs only about approx. 1 GB more than a generic APEX-I-Mini (approx. 12.5 GB). For that single extra gigabyte of VRAM, you get a massive jump in reasoning and syntactic stability.
Take a look at the tensor-by-tensor comparison table below to inspect the exact architectural differences and see why this specific allocation is optimal. That's specifically what this was built for:
| Architectural Component | Generic Automated Quants (Flat Q3_K_S / IQ3_S) |
Generic APEX-I-Mini (Baseline Recipe) | Our Handcrafted APEX-I-MiniPlus-V2 (IsValorum) | Perceived Quality & Real-World Impact |
|---|---|---|---|---|
Output Head (output.weight) |
Flat IQ3_S / Q3_K_S (approx. 3.44 BPW) |
Inherits base type Q3_K_M (approx. 3.44 BPW unarmored) |
Q6_K (approx. 6.56 BPW uncompromised) |
Eliminates Syntax & Vocabulary Hallucinations: Low-bit output heads cause tokenizer classification noise, breaking code indentation, brackets ({}, []), math symbols, and domain terms. Q6_K preserves near-FP16 output classification. |
Expert Routers (ffn_gate_inp.weight) |
Blindly quantized to 3-bit / unoptimized | Inherits base type Q3_K_M (approx. 3.44 BPW compressed) |
F32 uncompressed (32.0 BPW, 2 MB/layer) |
Zero Router Drift: In micro-expert models, even minuscule quantization errors in router logits misdirect tokens to wrong experts. Retaining uncompressed F32 guarantees 100% routing fidelity with virtually zero memory overhead (approx. 80 MB total). |
Attention & Language (attn_output, attn_qkv) |
Flat IQ3_S / Q3_K_S |
Q3_K on 34 middle layers (L3–36), Q4_K on 6 edge layers |
Q6_K for attn_output, IQ3_S for attn_qkv |
Contextual Retrieval Precision: Generic APEX reduces attention and language projections to Q3_K across 85% of layers. Our V2 build protects attention output in high-precision Q6_K and uses calibrated non-linear IQ3_S, ensuring flawless needle-in-a-haystack retrieval across deep 128k–256k context windows. |
Attention Gates (attn_gate.weight) |
Blindly compressed to 3-bit | Compressed to Q3_K (middle) / Q4_K (edges) |
Q8_0 (8.50 BPW) |
Attention Head Stability: Attention gates modulate query-key routing across hybrid attention layers. Keeping them in 8-bit prevents attention crosstalk and hallucination over long contexts. |
Shared Foundation Expert (ffn_*_shexp) |
Flat IQ3_S / Q3_K_S (3.44 BPW) |
Linear Q4_K (middle) / Q5_K (edges) |
IQ4_NL (4.50 BPW non-linear codebook) |
Foundational Knowledge Armor: The shared expert executes for 100% of tokens. In 256 micro-expert models, IQ4_NL non-linear codebooks preserve heavy-tailed outlier representations far better than standard linear quantization. |
| Core MoE Layers (Middle: 10–29) | Flat IQ3_S / Q3_K_S (uniform bit-rate across all layers) |
Aggressive IQ2_S (2.50 BPW) |
IQ3_XXS (3.06 BPW) + calibrated imatrix |
Above the Quality Threshold: Generic 2-bit IQ2_S baselines drop below the critical quality floor for 35B MoEs, resulting in perplexity spikes on reasoning tasks. Our IQ3_XXS with imatrix achieves deep compression (272 MiB → 98 MiB per block) without sacrificing logic. |
| Edge MoE Layers (Layers 0–9 & 30–39) | Flat IQ3_S / Q3_K_S (no layer-wise gradient) |
Q3_K (limited to first/last 5 layers only: L0–4, L35–39) |
IQ3_S (expanded to 10 input & 10 output layers) |
Protected Ingestion & Synthesis: Half of the model's layers (10 at input, 10 at output) form a non-linear armored envelope, preventing prompt misunderstanding and token degeneration across 256 micro-experts. |
Multimodal Vision (mmproj) |
Often omitted, or left as uncompressed FP16 (approx. 900 MB) |
Often omitted or separate uncompressed FP16 |
Bundled Q8_0 (582 MB) with 27 critical F32/F16 fallbacks |
Saves approx. 320 MB VRAM with Zero Loss: Handcrafted quantization preserves normalization and bias tensors in F32/F16, ensuring razor-sharp OCR, DOM viewport reading, and coordinate detection without visual noise. |
| Normalization & Biases | Often degraded | Standard | F32 uncompressed |
Numerical Stability: Prevents cumulative floating-point underflow/overflow across deep 40-layer computation. |
