-> [!NOTE]
-> ### ARCHITECTURE SELECTION GUIDE — MINIPLUS V2 & V2.1 EDITIONS
-> This repository hosts the **MiniPlus V2** edition of **KAT-Coder-V2.5-Dev**. Our releases are precision-engineered for specific hardware budgets and memory topologies. **V2 is NOT obsolete or "worse"; each edition serves distinct inference requirements:**
->
-> - **MiniPlus V2 (High Theoretical Layer Protection):** On paper, V2 provides extra protective envelopes on edge layers (10 layers in `IQ3_S` + `IQ4_NL` shared experts + `Q8_0` attention gates). However, **in practical inference benchmarks—even across extreme long-context windows exceeding +160K tokens—there is virtually NO perceptible difference in quality or reasoning compared to V2.1.**
-> - **MiniPlus V2.1 (System RAM Streaming Specialist with Deep Context):** Specially prepared to run **totally or partially in system RAM (DDR4/DDR5)** across large codebase contexts (up to 256k tokens). By replacing non-linear codebooks with linear `Q3_K` edge experts, keeping `Q8_0` attention gates, and upgrading shared foundation experts to `Q5_K` across all 40 layers, **it completely eliminates AVX2 CPU dequantization stalls (+24 to 28+ tok/s streaming)**. Depending on your processor and memory bandwidth (DDR4/DDR5), **streaming generation in system RAM can be almost as fast as having everything in VRAM**, while supporting deep context reserving GPU VRAM for the codebase KV cache while model weights stream from system RAM. It provides this massive RAM streaming acceleration for **only approx. 100 MB more**, which is completely negligible in system RAM.
->
-> **Which one should you choose? (Official Recommendation: V2.1)**
-> - **⭐ PRIMARY RECOMMENDATION — [KAT-Coder-V2.5-Dev APEX-I-MiniPlus V2.1](https://huggingface.co/IsValorum/KAT-Coder-V2.5-Dev-APEX-I-MiniPlus-V2.1-GGUF):** For virtually all users and deployments, **V2.1 is the strictly recommended release**. Empirically verified on WikiText-2, V2.1 achieves an outstanding **Perplexity of 5.5045 ± 0.1330** (ΔPPL ≈ +0.06 from unquantized baseline (approx. 5.44)), matching the token fidelity of **Q5_K / Q6_K** class quantizations while weighing only **approx. 14.7 GB** (same footprint as Q3_K_M). Furthermore, it completely eliminates AVX2 CPU stalls, providing blistering **+24 to 28+ tok/s streaming** under system RAM offload.
-> - **MiniPlus V2 Legacy:** Maintained for architectural transparency and users seeking specialized configurations for their workflow.
->
-> *Both editions are handcrafted and vastly outperform flat 3-bit quants and generic community APEX-I-Mini releases.*
-> To explore or download the **V2.1** edition of KAT-Coder-V2.5-Dev optimized for system RAM streaming, visit:
-> **[IsValorum/KAT-Coder-V2.5-Dev-APEX-I-MiniPlus-V2.1-GGUF](https://huggingface.co/IsValorum/KAT-Coder-V2.5-Dev-APEX-I-MiniPlus-V2.1-GGUF)**
-> [!WARNING]
-> ### DO NOT CONFUSE APEX-I-MINIPLUS WITH GENERIC COMMUNITY APEX-I-MINI!
-> **Regardless of release version (whether V1, V2, or V2.1), NEVER confuse handcrafted APEX-I-MiniPlus builds with generic community APEX-I-Mini releases:**
-> - **Generic Community APEX-I-Mini:** Uniformly compresses all core MoE experts down to aggressive 2-bit `IQ2_S` (dropping below the critical quality floor), leaves the sensitive token output head unarmored at 3-bit `Q3_K_M`, and compresses attention projections down to `Q3_K`. In deep reasoning models, this triggers severe perplexity spikes, syntax errors, and broken code brackets.
-> - **Handcrafted APEX-I-MiniPlus (All Editions by IsValorum):** Every single MiniPlus release—from V1 and V2 to V2.1—is a custom tensor-by-tensor architecture that preserves uncompressed `F32` router gates, armors the token output head in high-precision `Q6_K`, safeguards attention gates in `Q8_0`, and keeps core reasoning experts at or above calibrated 3-bit (`IQ3_XXS`/`IQ3_S`). Even our earlier builds vastly outperform generic community APEX recipes and flat 3-bit quants.

-### 🏅 Independent Benchmark of the APEX-I-MiniPlus Family (Occamy V2 Reference)
-> [!NOTE]
-> The benchmark below was performed on **Occamy-1.0 APEX-I-MiniPlus V2**, not on this specific model. It is included as independent evidence of the broader MiniPlus quantization approach.
-The **APEX-I-MiniPlus** quantization architecture powering this model was subjected to an extensive independent evaluation by Japanese AI researcher and evaluator [zephel01 (CoolZero)](https://note.com/zephel01/n/n71d3d7e6b70c?hl=en) on an **NVIDIA RTX 5090 (32GB)** workstation running `llama.cpp` CUDA `b11027` with FlashAttention (`-fa on -ctk q8_0 -ctv q8_0 -ngl 99`).
-The evaluation tested the APEX-I hybrid MoE engine across **348 unseeded trials** on SWE-bench style multi-file Python bug-fixing tasks with hidden `pytest` suites (`llmbench`):
-- **L6 Multi-File Code Generation (60 tasks):**
-  - **Context 32,768 (32K):** **93.3% Resolved** (46/60 tasks passed 5/5 consecutive trials; 20/20 on Easy–Hard).
-  - **Context 65,536 (65K):** **90.0% Resolved** (45/60 tasks passed 5/5 consecutive trials).
-  - **Match with 25–28 GB Models:** Matches or exceeds the resolution rate of full 25–28 GB models (such as `Ornith-1.5` and `Tiel-Coder` 35B-A3B) while consuming **over 10 GB less VRAM** (14.6 GB vs approx. 26 GB).
-- **Extreme Context VRAM Scaling (The Hybrid DeltaNet SSM Advantage):**
-  - **32K Context:** **14.6 GB** total VRAM allocation.
-  - **65K Context:** **15.1 GB** total VRAM allocation (only **+0.5 GB VRAM** added when doubling context!).
-  - *Architectural Explanation:* Because 30 of the 40 layers utilize Linear Attention / DeltaNet SSM ($O(1)$ constant recurrence memory), only the 10 full-attention anchor layers expand the KV cache. This proves empirically that **65,536 context runs 100% in VRAM on consumer 16GB GPUs (RTX 4080 / RTX 5080)** without offloading to system RAM.
-- **Measured Real-World Throughput:** Sustained single-stream generation of **approx. 247 – 251 tok/s** on NVIDIA RTX 5090.

-## 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. |
-| **Normalization & Biases** | Often degraded | Standard | **`F32` uncompressed** | **Numerical Stability:** Prevents cumulative floating-point underflow/overflow across deep 40-layer computation. |

-## Everyday Laptop Benchmarks (DDR4 / DDR5 RAM)
-### *Estimated Projections on Consumer Hardware*
-You do not need an expensive workstation to run a cutting-edge 35B Mixture-of-Experts coding model. Estimated throughput projections on a standard consumer laptop (Intel Core i5 / AMD Ryzen, 4GB/6GB Laptop GPU, 32GB DDR4/DDR5 RAM):
-- **GPU VRAM Allocation:** Uses only **approx. 3.8 GB VRAM** (fits effortlessly on budget 4GB/6GB laptop GPUs such as RTX 3050, 4050, or 2060).
-- **System Memory Offload:** Standard 32GB system RAM accommodates the remaining layers.
-- **Estimated Document / Code Ingestion (Prefill):** **300 to 450+ tokens/second** sustained across long prompt files.
-- **Estimated Streaming Generation:** **20 to 24+ tokens/second** sustained output across system RAM!
-> [!TIP]
-> **Pro Tip for Consumer Laptop Users:**
-> Because the bulk of the model runs from system memory in partial offload mode, standard autoregressive generation streams seamlessly at **20 to 24+ tokens/second** across everyday DDR4/DDR5 memory buses, perfectly sufficient for real-time IDE pair programming!

-## The 24GB Miracle: Full 256K Context Runs In VRAM!
-For developers running 24GB GPUs (RTX 3090, RTX 4090, or professional workstations), standard community 3-bit or 4-bit quants weigh 15.8 to 19.5 GiB in weights alone. When combined with KV cache and compute buffers for large codebases, they trigger immediate CUDA Out-Of-Memory crashes.
-**KAT-Coder APEX-I-MiniPlus-V2 fits massive contexts entirely within 24GB VRAM:**

-| :--- | :--- | :--- | :--- | :--- | :--- |
-| **32,768 (32k)** | `13.64 GiB` | `0.58 GiB` | `1.80 GiB` | **`16.02 GiB`** | Full offload on 24GB; partial on 16GB |
-| **65,536 (64k)** | `13.64 GiB` | `0.92 GiB` | `1.95 GiB` | **`16.51 GiB`** | Effortless fit on 24GB GPUs |
-| **131,072 (128k)**| `13.64 GiB` | `1.58 GiB` | `2.22 GiB` | **`17.44 GiB`** | Effortless fit on 24GB GPUs |
-| **262,144 (256k)**| `13.64 GiB` | `2.92 GiB` | `2.80 GiB` | **`19.36 GiB`** | **FULL 256K CODE REPO IN VRAM!** |
-*Note: Projections estimate approx. 4.64 GiB of headroom remaining on 24GB cards for system display buffers and tooling.*

+> [!NOTE]
+> ### ARCHITECTURE SELECTION GUIDE — MINIPLUS V2 & V2.1 EDITIONS
+> This repository hosts the **MiniPlus V2** edition of **KAT-Coder-V2.5-Dev**. Our releases are precision-engineered for specific hardware budgets and memory topologies. **V2 is NOT obsolete or "worse"; each edition serves distinct inference requirements:**
+>
+> - **MiniPlus V2 (High Theoretical Layer Protection):** On paper, V2 provides extra protective envelopes on edge layers (10 layers in `IQ3_S` + `IQ4_NL` shared experts + `Q8_0` attention gates). However, **in practical inference benchmarks—even across extreme long-context windows exceeding +160K tokens—there is virtually NO perceptible difference in quality or reasoning compared to V2.1.**
+> - **MiniPlus V2.1 (System RAM Streaming Specialist with Deep Context):** Specially prepared to run **totally or partially in system RAM (DDR4/DDR5)** across large codebase contexts (up to 256k tokens). By replacing non-linear codebooks with linear `Q3_K` edge experts, keeping `Q8_0` attention gates, and upgrading shared foundation experts to `Q5_K` across all 40 layers, **it completely eliminates AVX2 CPU dequantization stalls (+24 to 28+ tok/s streaming)**. Depending on your processor and memory bandwidth (DDR4/DDR5), **streaming generation in system RAM can be almost as fast as having everything in VRAM**, while supporting deep context reserving GPU VRAM for the codebase KV cache while model weights stream from system RAM. It provides this massive RAM streaming acceleration for **only approx. 100 MB more**, which is completely negligible in system RAM.
+>
+> **Which one should you choose? (Official Recommendation: V2.1)**
+> - **⭐ PRIMARY RECOMMENDATION — [KAT-Coder-V2.5-Dev APEX-I-MiniPlus V2.1](https://huggingface.co/IsValorum/KAT-Coder-V2.5-Dev-APEX-I-MiniPlus-V2.1-GGUF):** For virtually all users and deployments, **V2.1 is the strictly recommended release**. Empirically verified on WikiText-2, V2.1 achieves an outstanding **Perplexity of 5.5045 ± 0.1330** (ΔPPL ≈ +0.06 from unquantized baseline (approx. 5.44)), matching the token fidelity of **Q5_K / Q6_K** class quantizations while weighing only **approx. 14.7 GB** (same footprint as Q3_K_M). Furthermore, it completely eliminates AVX2 CPU stalls, providing blistering **+24 to 28+ tok/s streaming** under system RAM offload.
+> - **MiniPlus V2 Legacy:** Maintained for architectural transparency and users seeking specialized configurations for their workflow.
+>
+> *Both editions are handcrafted and vastly outperform flat 3-bit quants and generic community APEX-I-Mini releases.*
+> To explore or download the **V2.1** edition of KAT-Coder-V2.5-Dev optimized for system RAM streaming, visit:
+> **[IsValorum/KAT-Coder-V2.5-Dev-APEX-I-MiniPlus-V2.1-GGUF](https://huggingface.co/IsValorum/KAT-Coder-V2.5-Dev-APEX-I-MiniPlus-V2.1-GGUF)**
+> [!WARNING]
+> ### DO NOT CONFUSE APEX-I-MINIPLUS WITH GENERIC COMMUNITY APEX-I-MINI!
+> **Regardless of release version (whether V1, V2, or V2.1), NEVER confuse handcrafted APEX-I-MiniPlus builds with generic community APEX-I-Mini releases:**
+> - **Generic Community APEX-I-Mini:** Uniformly compresses all core MoE experts down to aggressive 2-bit `IQ2_S` (dropping below the critical quality floor), leaves the sensitive token output head unarmored at 3-bit `Q3_K_M`, and compresses attention projections down to `Q3_K`. In deep reasoning models, this triggers severe perplexity spikes, syntax errors, and broken code brackets.
+> - **Handcrafted APEX-I-MiniPlus (All Editions by IsValorum):** Every single MiniPlus release—from V1 and V2 to V2.1—is a custom tensor-by-tensor architecture that preserves uncompressed `F32` router gates, armors the token output head in high-precision `Q6_K`, safeguards attention gates in `Q8_0`, and keeps core reasoning experts at or above calibrated 3-bit (`IQ3_XXS`/`IQ3_S`). Even our earlier builds vastly outperform generic community APEX recipes and flat 3-bit quants.

+### 🏅 Independent Benchmark of the APEX-I-MiniPlus Family (Occamy V2 Reference)
+> [!NOTE]
+> **External report:** [zephel01 independently benchmarked Occamy V2](https://note.com/zephel01/n/n71d3d7e6b70c?hl=en). The benchmark below was performed on **Occamy-1.0 APEX-I-MiniPlus V2**, not on this specific model. It is included as independent evidence of the broader MiniPlus quantization approach.
+The **APEX-I-MiniPlus** quantization architecture powering this model was subjected to an extensive independent evaluation by Japanese AI researcher and evaluator [zephel01 (CoolZero)](https://note.com/zephel01/n/n71d3d7e6b70c?hl=en) on an **NVIDIA RTX 5090 (32GB)** workstation running `llama.cpp` CUDA `b11027` with FlashAttention (`-fa on -ctk q8_0 -ctv q8_0 -ngl 99`).
+The evaluation tested the APEX-I hybrid MoE engine across **348 unseeded trials** on SWE-bench style multi-file Python bug-fixing tasks with hidden `pytest` suites (`llmbench`):
+- **L6 Multi-File Code Generation (60 tasks):**
+  - **Context 32,768 (32K):** **93.3% Resolved** (46/60 tasks passed 5/5 consecutive trials; 20/20 on Easy–Hard).
+  - **Context 65,536 (65K):** **90.0% Resolved** (45/60 tasks passed 5/5 consecutive trials).
+  - **Match with 25–28 GB Models:** Matches or exceeds the resolution rate of full 25–28 GB models (such as `Ornith-1.5` and `Tiel-Coder` 35B-A3B) while consuming **over 10 GB less VRAM** (14.6 GB vs approx. 26 GB).
+- **Extreme Context VRAM Scaling (The Hybrid DeltaNet SSM Advantage):**
+  - **32K Context:** **14.6 GB** total VRAM allocation.
+  - **65K Context:** **15.1 GB** total VRAM allocation (only **+0.5 GB VRAM** added when doubling context!).
+  - *Architectural Explanation:* Because 30 of the 40 layers utilize Linear Attention / DeltaNet SSM ($O(1)$ constant recurrence memory), only the 10 full-attention anchor layers expand the KV cache. This proves empirically that **65,536 context runs 100% in VRAM on consumer 16GB GPUs (RTX 4080 / RTX 5080)** without offloading to system RAM.
+- **Measured Real-World Throughput:** Sustained single-stream generation of **approx. 247 – 251 tok/s** on NVIDIA RTX 5090.

+## 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. |
+| **Normalization & Biases** | Often degraded | Standard | **`F32` uncompressed** | **Numerical Stability:** Prevents cumulative floating-point underflow/overflow across deep 40-layer computation. |

+## Everyday Laptop Benchmarks (DDR4 / DDR5 RAM)
+### *Estimated Projections on Consumer Hardware*
+You do not need an expensive workstation to run a cutting-edge 35B Mixture-of-Experts coding model. Estimated throughput projections on a standard consumer laptop (Intel Core i5 / AMD Ryzen, 4GB/6GB Laptop GPU, 32GB DDR4/DDR5 RAM):
+- **GPU VRAM Allocation:** Uses only **approx. 3.8 GB VRAM** (fits effortlessly on budget 4GB/6GB laptop GPUs such as RTX 3050, 4050, or 2060).
+- **System Memory Offload:** Standard 32GB system RAM accommodates the remaining layers.
+- **Estimated Document / Code Ingestion (Prefill):** **300 to 450+ tokens/second** sustained across long prompt files.
+- **Estimated Streaming Generation:** **20 to 24+ tokens/second** sustained output across system RAM!
+> [!TIP]
+> **Pro Tip for Consumer Laptop Users:**
+> Because the bulk of the model runs from system memory in partial offload mode, standard autoregressive generation streams seamlessly at **20 to 24+ tokens/second** across everyday DDR4/DDR5 memory buses, perfectly sufficient for real-time IDE pair programming!
