# Training

Transitional training recipes for Timmy's sovereign model. These files are
useful as reference configs and export helpers, but they are not the canonical
home of Timmy's lived training data.

Canonical data should live in `timmy-home` under gameplay trajectories,
research artifacts, and `training-data/` exports such as DPO pairs.

## Install

```bash
pip install axolotl mlx-lm lm-evaluation-harness pyyaml
```

## Commands

```bash
make train-local    # LoRA on Apple Silicon (MLX) — free, ~30 min on M3 Max
make train-cloud    # QLoRA on cloud GPU (Axolotl) — ~$1/run on A100
make eval           # Standard benchmarks via lm-eval-harness against Ollama
make vibes          # Hand-picked prompts → human review (the sacred test)
make ingest         # Pull heartbeat trajectories into training data
make curated        # Regenerate curated exemplar dataset
make convert        # Convert merged data to MLX train/valid format
make help           # Show all targets
```

## Status

This directory exists to avoid re-growing a bespoke training harness while the
system boundary is being cleaned up.

- Keep thin recipes and export helpers here only when they directly support the
  Hermes sidecar.
- Keep generated data, DPO pairs, and other lived artifacts in `timmy-home`.
- Prefer deleting stale pipeline code over expanding it.

## What's proprietary

The data (curated exemplars, preference pairs, trained weights) is proprietary. The configs and process are open.

## Training Results (March 2026)

### timmy:v0.1-q4

| Detail | Value |
|--------|-------|
| Base model | mlx-community/Hermes-3-Llama-3.1-8B-4bit |
| Training data | 1,214 samples from Hermes session DB |
| Method | LoRA rank 8, 16 layers, lr 2e-6, 1000 iters |
| Peak memory | 7.8 GB (Apple Silicon) |
| Best val loss | 2.134 (iter 800) |
| Final model | timmy:v0.1-q4 in Ollama (4.9GB, Q4_K_M) |
| Inference speed | ~48 tok/s on M3 Max |

### Key Insight

The base model's RLHF priors override LoRA on crisis/faith — the most important parts of SOUL.md. Fix: inference-time grounding (inject SOUL.md crisis protocol) + larger pure-Timmy corpus over time.
