> [!NOTE] > **Domain Specialization Warning:** Sovereign Mahiru MoE is structurally optimized for **cybersecurity, secure coding practices, and vulnerability detection**. Her underlying coding weights are aligned to resolve defensive security implementations (e.g., input sanitation, buffer overflow mitigations) rather than competitive algorithmic puzzle-solving (the focus of the HumanEval benchmark). > > The benchmark results below represent the performance of the **Q4 Quantized Model (Q4_K_M)** format running on Kaggle. Quantization reduces the precision of the model weights to 4-bits, which introduces slight logical degradation compared to the full precision version. # Sovereign Mahiru MoE: HumanEval Optimization & Routing Report --- ## Q4 Quantized Model (Q4_K_M) Performance Comparison | Configuration | Active Params/Token | Total Params | HumanEval Score (Direct Completion) | Correct Tasks | Avg.

Forcing Top-2 expert routing on a model trained/fine-tuned primarily for Top-1 routing leads to a known phenomenon in Mixture-of-Experts (MoE) architectures: 1. **Routing Calibration Mismatch:** In an MoE model, the gating network output weights are optimized to route to the single best expert (Top-1). When we force Top-2 routing at runtime, the second expert's output is mixed with the first expert's output using weights that were not calibrated during pretraining or instruction tuning. The secondary expert introduces **noise rather than cooperative signal**, leading to slight degradation in code synthesis coherence (dropping from 32.93% to 30.49%). 2. **Parameter Overlap & Dilution:** In Top-2 mode, the active parameter size per token increases from 3.0B to 5.8B. However, because the gating distribution has a steep entropy gradient (often putting >95% probability on the top expert), blending the second expert's representation dilutes the focused coding representation of the primary expert. 3. **Inference Latency & Speed:** Forcing Top-2 expert activation successfully leverages more computation per token (5.8B parameters), and the average generation speed remained highly efficient at ~32.8 tokens/sec on the Tesla P100. --- ## Recommendations & Next Steps 1. **Revert to Top-1 Active Routing for Coding Tasks:** For coding tasks where syntax precision is critical, the model performs better with its native, calibrated **Top-1 routing** configuration. We should keep `llama.expert_used_count` at its default value of `1`. 2. **Explore Soft-Gating Tuning:** If Top-2 routing is desired for broader knowledge retention, the router (gating) layers must be specifically fine-tuned under a Top-2 loss constraint rather than binary-patched at runtime. --- # Sovereign Mahiru MoE (3B) Q8_0 Precision Evaluation > [!NOTE] > The benchmark results below represent the performance of the **Q8 Quantized Model (Q8_0)** format running on Kaggle. It was evaluated using native **Llama-3 instruction templates** and a **multi-stage extraction pipeline** to prevent formatting/indentation degradation. ## Q8_0 Precision Performance Comparison | Configuration | Active Params/Token | Think Tag? | HumanEval Score | Correct Tasks | Avg. Speed (TPS) | Formatting/Syntax Errors | | :--- | :---: | :---: | :---: | :---: | :---: | :---: | | **Q8_0 Direct (Optimized)** | 3.0B | No | **48.78%** | 80 / 164 | **53.3 tokens/sec** | **1 / 84 failures** | | **Q8_0 Thinking (Optimized)** | 3.0B | Yes | **49.39%** | 81 / 164 | **52.5 tokens/sec** | **5 / 83 failures** | --- ## Key Improvements & Insights (Q8_0) ### 1. Accuracy Uplift (+16.46% absolute) By elevating quantization from Q4 to Q8_0 and enforcing correct template wrapping, the model's coding logic improved dramatically, raising scores from **32.93% to 48.78%** (Direct) and **49.39%** (Thinking). ### 2. Elimination of Formatting Noise By implementing a custom **robust multi-stage code parser** that searches character offsets in closed/unclosed markdown blocks, structural indentation errors dropped from ~35% of failure modes down to practically zero (1 in Direct, 5 in Thinking). ### 3. GPU Compilation Speedups Inference speed reached **53.3 TPS** on Tesla P100 GPUs, achieving a ~50% latency reduction over Q4 baselines due to highly optimized `llama-cpp-python` source builds. --- ## Q8_0 Failure Mode Breakdown ### 1. Direct Completion Failures (84 total) * **Assertion Failures (Logic incorrect):** 60 * **Runtime Exceptions:** 23 * **Syntax/Formatting Errors:** 1 ### 2. Thinking-Assisted Failures (83 total) * **Assertion Failures (Logic incorrect):** 56 * **Runtime Exceptions:** 22 * **Syntax/Formatting Errors:** 5 --- ## Important Evaluation Context & Latent Coding Potential To properly interpret these benchmark results, several factors regarding the model architecture and evaluation environment must be highlighted: 1. **Non-Specialized Generalist Architecture:** Sovereign Mahiru is a generalist Mixture-of-Experts (MoE) model. It was **not** fine-tuned on dedicated programming datasets, nor does it contain specialized coder/math expert weights (unlike models like DeepSeek-Coder or Qwen-Coder). That a generalist 3B active parameter model achieves ~49% accuracy shows strong underlying logical capability. 2. **Raw Zero-Shot Evaluation (No System Prompts or Cues):** The benchmark was performed with minimal, raw zero-shot direct completion tasks. No system prompt (e.g., *"You are an expert Python developer..."*), few-shot coding examples, or step-by-step thinking guidance was provided to bias or prime the model. 3. **No Execution Feedback or Agentic Verification:** This evaluation reflects a single-pass, feed-forward response. In interactive agent environments or systems employing self-correction loops (running syntax/test feedback through the model), scores are expected to be substantially higher. 4. **Greedy Sampling (Pass@1) Limitation:** We used strict greedy decoding (`temperature = 0.0`) for a single attempt. Standard benchmark methodology (e.g., Pass@10 or temperature sampling with consensus voting) typically yields a 10% to 15% increase in score by allowing the model to correct pathing errors over multiple attempts.
