Pythia 1.4B -- 500 Facts via Neural Reclamation

This model has 500 novel facts from 2023-2024 written directly into its weights using jBlaze's Neural Reclamation pipeline. No fine-tuning. No adapters. No gradient-based training loop. Direct weight surgery on MLP output projections.

These are facts the base model could not possibly know -- Pythia 1.4B was trained on data through early 2023. The implanted knowledge covers AI releases (GPT-4, Claude 3, Llama 2, Gemini), world events (2024 Paris Olympics), sports results, scientific breakthroughs, and more.

Results

Pass LR Steps Recall General PPL
Pass 1 2e-3 20 165/500 (33%) Baseline Baseline
Pass 2 7e-4 20 434/500 (87%) Stable Stable
Pass 3 3e-4 20 489/500 (98%) Stable Stable

489 out of 500 facts recalled at 98% accuracy. PPL held flat across all three passes. General knowledge probes stable throughout. Language coherence 5/5.

250 facts reached perfect 100% recall. The full 500 at 98%.

Why This Matters

Gradient-based training (LoRA, fine-tuning) destroyed this same model rapidly:

Method Facts Survived General Cap Perplexity
Gradient (LoRA v1) 50 10.0% 459.6
Gradient (LoRA v2, conservative) ~125 35.0% 96.5
Neural Reclamation (this model) 489 Stable Stable

LoRA v1 with standard settings killed the model at 50 facts. LoRA v2 with every conservative setting collapsed at 125 facts. Neural Reclamation loaded 489 facts with zero degradation.

The Pipeline

Neural Reclamation works in stages:

  1. Erase targeted knowledge from MLP weight matrices using contrastive activation direction projection
  2. Stabilize the hollowed model by writing back essential general knowledge
  3. Write novel facts into the freed representational capacity
  4. Passidation (3-pass rerun) -- rerun all facts at tapering learning rates. Self-balancing: forgotten facts have high loss and get pushed hard, already-learned facts have near-zero loss and are barely touched.
