# 12% Pruned, 61.0 HUMANEVAL (base 62.2)

**Qwen2.5-Coder-7B** recovered to within calibration tolerance of the unmodified base via KL-distillation compensation LoRA.

- **HUMANEVAL**: 61.0 (base 62.2, Δ -1.2)
- **HUMANEVAL+PLUS**: 53.0 (base 53.7, Δ -0.7)

**Qwen2.5-Coder-7B** with cryptographic provenance via the [ForgeAlloy](https://github.com/CambrianTech/forge-alloy) chain of custody. Scores **61.0 humaneval** against the unmodified base's **62.2**, recovered to within calibration tolerance after head pruning + distillation. Ships with the per-problem evaluation outputs so the score is independently verifiable.


## Benchmarks

| Benchmark | Score | Base | Δ | Verified |
|---|---|---|---|---|
| **humaneval** | **61.0** | 62.2 | -1.2 | ✅ Result hash |
| **humaneval_plus** | **53.0** | 53.7 | -0.7 | ✅ Result hash |


## What Changed (Base → Forged)

| | Base | Forged | Delta |
|---|---|---|---|
| **Pruning** | None | 12% heads (activation-magnitude) | **-12%** params ✅ |
| **compensation-lora** | None | rank=16 | q_proj, k_proj, v_proj, o_proj... |
| **Pipeline** | | prune → lora → lora → eval | 1 cycles |

## Runs On

| Device | Format | Size | Speed |
|--------|--------|------|-------|
| **NVIDIA GeForce RTX 5090** | fp16 | — | Verified |
| MacBook Pro 32GB | fp16 | 8.0GB | Expected |
| MacBook Air 16GB | Q8_0 | ~4.0GB | Expected |
| MacBook Air 8GB | Q4_K_M | ~2.5GB | Expected |
| iPhone / Android | Q4_K_M | ~2.5GB | Expected |

## Quick Start

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("continuum-ai/v2-7b-coder-compensated",
    torch_dtype="auto", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("continuum-ai/v2-7b-coder-compensated")

inputs = tokenizer("def merge_sort(arr):", return_tensors="pt").to(model.device)
output = model.generate(**inputs, max_new_tokens=200)
print(tokenizer.decode(output[0], skip_special_tokens=True))
```


## Methodology

Produced via head pruning, LoRA fine-tuning, KL-distillation compensation against the unmodified teacher. Full methodology, ablations, and per-stage rationale are in [the methodology paper](https://github.com/CambrianTech/continuum/blob/main/docs/papers/PLASTICITY-COMPACTION.md) and the companion [`MODEL_METHODOLOGY.md`](MODEL_METHODOLOGY.md) in this repository. The pipeline ran as `prune → lora → lora → eval` over 1 cycle on NVIDIA GeForce RTX 5090.

## Limitations

- This model is currently a methodology demonstration rather than a Pareto-optimal artifact at any specific hardware tier. For production code workloads on smaller hardware, the unmodified Qwen2.5-Coder-7B at standard quantization (Q4_K_M / Q5_K_M / Q8_0) may be a better fit pending the larger Qwen3.5+ forges that exercise the pruning dimension where this methodology actually wins.
- Validated on HumanEval / HumanEval+ for English-language Python code completion. Performance on other programming languages, code paradigms (functional, embedded, kernel), or code-adjacent domains (SQL, regex, shell) has not been measured.
- Ships as fp16 only. GGUF quantization tiers (Q5_K_S / Q3_K_M / Q2_K) are not yet published for this artifact; the per-tier comparison from the development log showed base+quant dominates v2+quant at every VRAM tier on the same 7B base, which is why the methodology validation here uses fp16 and the production GGUF publishes are reserved for the Qwen3.5+ forges where the dimension flips.
- Vision modality not yet wired in. The Continuum sensory architecture treats vision as first-class for personas, but this 7B coder artifact is text-only.
