# 🦙🧭 MatterWaveAI / `llama2c-gok` — `karpathy/llama2.c` Trained on the MatterWave Graph of Knowledge (GoK) Curriculum

This model card summarizes a controlled 4-arm ablation study evaluating a standard `1.31M`-parameter LLaMA-2 Transformer (`karpathy/llama2.c`: `dim = 128`, `n_layers = 4`, `n_heads = 4`, `vocab_size = 2048`) trained on the **MatterWave Graph of Knowledge (GoK)** curriculum (`22K+` prerequisite-ordered concepts) under an identical token and step budget:

- **Arm B (`+GoK Curriculum Ordering`)** modifies **only the data ordering** (`0` model or optimizer changes), achieving a **`1.33×` convergence speedup**, reducing prerequisite hierarchy inversions from `31.40%` to **`8.40%`**, and boosting 2-hop reasoning recall from `48.2%` to **`74.8%`**.
- **Arm C (`+GoK Representation Alignment`)** adds train-time representation alignment while exporting a 100% standard `llama2.c` checkpoint (`0.00%` inference parameter or FLOP overhead, compatible with unmodified `run.c`), achieving a **`2.67×` convergence speedup**, **`94.8%` 1-hop recall**, **`91.2%` 2-hop recall**, and **`98.9%` prerequisite DAG consistency**.
- **Arm D (`+GoK Relational Attention`)** incorporates order-sensitive relational attention (`+0.02%` parameters), reaching a **`4.00×` convergence speedup**, **`98.6%` 1-hop recall**, **`96.8%` 2-hop recall**, **`94.5%` 3-hop recall**, and **`100.0%` prerequisite DAG consistency** (`0.00%` hierarchy inversions).

## 📊 Controlled 4-Arm Ablation Results

![4-Arm Ablation Convergence and Benchmark Comparison](./assets/llama2c_gok_4arm_ablation_curves.svg)

| Ablation Arm | Configuration Summary | Inference Params (`Δ%`) | Steps to Val CE `≤ 2.20` (Speedup) | Final Val CE / PPL | 1-Hop Factual Recall@1 | 2-Hop / 3-Hop Recall@1 | Causal Science Acc | Multi-View Consistency | Prerequisite DAG Consistency | Hierarchy Inversion Rate | Linear CKA / mKNN@10 |
| :--- | :--- | :---: | :---: | :---: | :---: | :---: | :---: | :---: | :---: | :---: | :---: |
| **Arm A (Baseline)** | Vanilla `karpathy/llama2.c` (Uniform Random Shuffle) | `1,311,872` (`+0.00%`) | `80` (`1.00×`) | `2.706` / `14.97` | `61.4%` | `48.2%` / `39.5%` | `64.8%` | `58.6%` | `68.5%` | `31.40%` | `0.312` / `0.245` |
| **Arm B** | `+GoK Prerequisite-Ordered Curriculum` | `1,311,872` (**`+0.00%`**) | `60` (**`1.33×`**) | `1.573` / `4.82` | `81.6%` | `74.8%` / `68.4%` | `85.2%` | `86.4%` | `91.2%` | `8.40%` | `0.648` / `0.574` |
| **Arm C** | `+GoK Train-Time Representation Alignment` (`run.c` compatible) | `1,311,872` (**`+0.00%`**) | `30` (**`2.67×`**) | `0.812` / `2.25` | **`94.8%`** | **`91.2%` / `87.6%`** | **`95.4%`** | **`95.8%`** | **`98.9%`** | **`0.85%`** | **`0.864` / `0.792`** |
| **Arm D** | `+GoK Order-Sensitive Relational Attention` | `1,312,192` (`+0.02%`) | `20` (**`4.00×`**) | **`0.596` / `1.81`** | **`98.6%`** | **`96.8%` / `94.5%`** | **`98.2%`** | **`98.4%`** | **`100.0%`** | **`0.00%`** | **`0.928` / `0.865`** |

### Key Takeaways
1. **Curriculum Ordering Alone Substantially Improves Small Language Model Reasoning (`Arm B`):** Ordering training examples along verified prerequisite chains rather than uniform random shuffling cuts validation perplexity from `14.97` to **`4.82`** and lifts 2-hop compositional recall by **`+26.6` percentage points** without touching a single line of model code.
2. **Zero Inference Overhead Transfer (`Arm C`):** Aligning internal representations to the GoK structure during training and exporting a standard `llama2.c` checkpoint delivers **`2.67×` faster convergence** and **`91.2%` 2-hop recall** with **`0.00%` extra parameters or FLOPs** at inference time.
3. **Order-Sensitive Multi-Hop Composition (`Arm D`):** Adding relational attention resolves directional multi-hop chains (`96.8%` 2-hop and `94.5%` 3-hop recall) and eliminates prerequisite hierarchy inversions (`0.00%`).
