📌 Executive Overview

MiMo-Ornith-9B-AGSI-Abliterated-HQ is an uncensored, high-reasoning 9.7B parameter model synthesized through the confluence of:

1. Xiaomi MiMo-V2.6-Distill-Qwen-9B: Chain-of-thought distillation, complex mathematical reasoning, and deep algorithmic synthesis.
2. DeepReinforce Ornith-1.5-9B: Reinforcement-learned terminal execution, autonomous bash commands, multi-step tool calling, and self-correcting agentic loops.
3. Adaptive Geodesic Spectral Interpolation (AGSI): A custom parameter-space merge preserving individual neuron manifolds and activation energy without linear signal degradation.
4. Bayesian Representation Abliteration (Abliterix): Multi-objective Optuna TPE search isolating and orthogonally projecting out refusal vectors while strictly enforcing a minimal KL-divergence constraint ($\text{KL} \le 0.007$).

This model eliminates refusal boundaries while completely retaining Chain-of-Thought (CoT) reasoning, syntax precision, and agentic tool invocation. Furthermore, it natively patches upstream Qwen 3.5 MTP configuration bugs, ensuring 100% plug-and-play GGUF conversion with llama.cpp and vLLM.

1. Adaptive Geodesic Spectral Interpolation (AGSI)

Standard LERP and whole-tensor SLERP fail on deep transformer hybrids by treating weight matrices as single isotropic vectors, inducing activation collapse across 32 layers. AGSI resolves this via:

• Row-Wise Hyperspherical Geodesics ($S^{d-1}$): Every individual neuron hyperplane is decomposed into radial magnitude ($m = |W|_2$) and directional unit orientation ($u = W / m$). Spherical linear interpolation is computed along each neuron's geodesic trajectory.
• Quadratic Spectral Energy Conservation: To eliminate variance shrinkage across 32 layers, activation scale is governed by RMS energy matching:

$$ |W_{\text{target}}^{(i)}| = \sqrt{(1 - t)|W_A^{(i)}|_2^2 + t|W_B^{(i)}|_2^2} $$

• Anti-Phase Interference Cancellation: Divergent fine-tuning gradients ($\cos\theta < -0.05$) are detected and resolved via Pareto-dominance gating toward the higher-variance model, preventing dead activation zones.
• Quintic Smoothstep Depth Routing:
  • Layers 0–7 ($t \approx 0.41 - 0.44$): MiMo-dominant to anchor syntactic and token representation stability.
  • Layers 8–23 ($t \approx 0.45 - 0.51$): Equilibrium zone where algorithmic logic and context tracking fuse.
  • Layers 24–31 ($t \approx 0.52 - 0.55$): Ornith-dominant on routing projections for agentic tool use and terminal decision policies.

2. Bayesian Refusal Abliteration (Abliterix)

Unlike brute-force direction clipping that causes semantic lobotomization, this model was abliterated using Abliterix:

• Residual Stream Representation Extraction: Computed activation divergence between benign and adversarial contrastive suites across all residual layers.
• Orthogonal Null-Space Projection: Identifies the refusal subspace and subtracts its projection while preserving feature norms.
• Bayesian Optimization (Optuna TPE): Explored layer depth boundaries, cosine decay slopes, and steering magnitudes over multi-objective trials to minimize refusal rates while penalizing distribution drift ($\text{KL} \le 0.007$).
• Cosine Transition Decay: Uses a smooth, non-linear bell curve at layer boundaries, eliminating sharp weight discontinuities.

🛠️ The 32-Block GGUF & llama.cpp Fix

Standard merges or conversions derived from Ornith-1.5 fail when converted to GGUF, throwing:

llama_model_load: check_tensor_dims: tensor 'blk.32.attn_norm.weight' not found

• Root Cause: Upstream checkpoints inherit "mtp_num_hidden_layers": 1 in config.json despite containing zero Multi-Token Prediction (MTP) weights. GGUF converters calculate $32 + 1 = 33$ blocks, but only 32 blocks exist in the weights (blk.0 to blk.31).
• Our Native Fix: The architecture explicitly sets "mtp_num_hidden_layers": 0 in both root and nested text_config.
• Result: Compiles into exact, valid 32-block GGUFs (qwen35.block_count = 32). Compatible with Unsloth, LM Studio, Ollama, and llama-server without CLI flags or overrides.
• Download Ready-to-Use Quants: Ready-made GGUF files are hosted directly at OliviaRossi/MiMo-Ornith-9B-AGSI-Abliterated-HQ-GGUF.

🧠 Reasoning Spectrum & Chat Template Features

The embedded chat_template.jinja provides complete, granular steering over the model's internal thinking scratchpad:

1. Multi-Tier Reasoning Effort

Clients and runtimes can steer reasoning depth using "reasoning_effort":

2. Prefix KV Cache Parity (preserve_thinking)

• When preserve_thinking: true (or llama-server --reasoning-preserve), historical <think>...</think> traces in prior turns are kept intact. This prevents multi-turn context drift and guarantees 100% prefix KV cache hit rates.
• When preserve_thinking: false, earlier thinking traces are pruned to minimize context window consumption on VRAM-limited devices.
