  • LLaVA models (vision processing)
  • Whisper variants (audio processing)

Recommendation: Start with text-only models.

Very Large Models

Unless you have substantial resources (64GB+ RAM):

  • Models > 70B parameters
  • MoE models with high parameter counts

Unsupported Architectures

Blasphemer does not support:

  • SSMs/hybrid models (Mamba, etc.)
  • Models with inhomogeneous layers
  • Certain novel attention mechanisms

Architecture Compatibility

Well-Tested (High Success Rate):

  • Llama 3/3.1 (all sizes) ⭐
  • Mistral 7B (all versions) ⭐
  • Qwen 2.5 (7B, 14B, 32B)

Tested (Moderate Success):

  • Gemma 2 (requires patience)
  • Command R (standard version)
  • Yi models (some variants)

Experimental (Low Success):

  • Phi-3 (all variants)
  • Very small models (< 3B)
  • Highly aligned corporate models

Hardware Recommendations

For Apple Silicon (MPS):

  • Recommended: 7B-14B models
  • Maximum: 30B models (with quantization)
  • Processing time: 2-3x slower than NVIDIA GPU

LM Studio Integration

After Blasphemer processes a model, you can use it in LM Studio by converting to GGUF format.

llama.cpp Installation

llama.cpp has been installed and configured:

  • Repository: /Users/christopher.bradford/blasphemer/llama.cpp
  • Helper Script: /Users/christopher.bradford/blasphemer/convert-to-gguf.sh
  • Built with: Metal support for Apple Silicon GPU acceleration

Converting Models to GGUF

Using the Helper Script (Recommended)

# Default Q4_K_M quantization (good balance)
./convert-to-gguf.sh ~/blasphemer-models/your-model-blasphemer

# Custom quantization level
./convert-to-gguf.sh ~/blasphemer-models/your-model-blasphemer output-name Q5_K_M

# View help
./convert-to-gguf.sh

Available Quantization Types

Type Size (7B) Quality Use Case
Q4_K_M ~4.5GB Good Recommended balance
Q5_K_M ~5.3GB Better Higher quality
Q8_0 ~8GB High Maximum quality
F16 ~14GB Full No quality loss

Perplexity Impact:

  • Q4_K_M: +0.18 ppl
  • Q5_K_M: +0.06 ppl
  • Q8_0: +0.00 ppl (minimal impact)

Manual Conversion (Advanced)

If you prefer to use llama.cpp tools directly:

Step 1: Convert to F16 GGUF

source venv/bin/activate
python llama.cpp/convert_hf_to_gguf.py ~/blasphemer-models/your-model \
  --outfile ~/blasphemer-models/your-model-f16.gguf \
  --outtype f16

Step 2: Quantize

./llama.cpp/build/bin/llama-quantize \
  ~/blasphemer-models/your-model-f16.gguf \
  ~/blasphemer-models/your-model-Q4_K_M.gguf \
  Q4_K_M

Loading in LM Studio

After conversion:

  1. Open LM Studio
  2. The .gguf file will automatically appear in the models list
  3. Or manually load via "Load Model" → select the GGUF file
  4. Start using your decensored model

Uploading to Hugging Face

Method 1: During Optimization (SafeTensors)

During Blasphemer's save prompt:

  1. Choose "Upload the model to Hugging Face"
  2. Enter your HF token when prompted
  3. Model uploads in SafeTensors format
  4. Others can download and use with transformers library

Method 2: Upload GGUF Files (Recommended for LM Studio Users)

Blasphemer includes an upload_gguf.py script for uploading quantized GGUF models to Hugging Face. This is ideal for sharing models that work directly in LM Studio.

Quick Example:

# Upload a quantized model with auto-generated model card
python upload_gguf.py \
    Llama-3.1-8B-Blasphemer-Q4_K_M.gguf \
    --repo-name "Llama-3.1-8B-Blasphemer-GGUF" \
    --create-card

Prerequisites:

cd ~/blasphemer
source venv/bin/activate
huggingface-cli login  # Enter your token from https://huggingface.co/settings/tokens

Basic Upload:

# Upload a single quantized model with auto-generated model card
python upload_gguf.py \
    Llama-3.1-8B-Blasphemer-Q4_K_M.gguf \
    --repo-name "Llama-3.1-8B-Blasphemer-GGUF" \
    --create-card

Upload Multiple Quantizations:

# Upload Q4_K_M (most popular - 4.5GB)
python upload_gguf.py \
    Llama-3.1-8B-Blasphemer-Q4_K_M.gguf \
    --repo-name "Llama-3.1-8B-Blasphemer-GGUF" \
    --create-card

# Upload Q5_K_M (higher quality - 5.5GB)
python upload_gguf.py \
    Llama-3.1-8B-Blasphemer-Q5_K_M.gguf \
    --repo-name "Llama-3.1-8B-Blasphemer-GGUF" \
    --message "Add Q5_K_M quantization"

# Upload F16 (full precision - 15GB, for power users)
python upload_gguf.py \
    Llama-3.1-8B-Blasphemer-F16.gguf \
    --repo-name "Llama-3.1-8B-Blasphemer-GGUF" \
    --message "Add F16 full precision version"

What the Script Does:

  • ✅ Creates Hugging Face repository automatically
  • ✅ Uploads GGUF files with progress display
  • ✅ Generates professional model card with your metrics
  • ✅ Includes usage instructions for LM Studio, llama.cpp, and Python
  • ✅ Proper credits and citations

Custom Options:

# Specify custom username
python upload_gguf.py \
    model.gguf \
    --repo-name "My-Model-GGUF" \
    --username "my-hf-username"

# Custom commit message
python upload_gguf.py \
    model.gguf \
    --repo-name "My-Model-GGUF" \
    --message "Update with improved quantization"

Model Card Contents:

The auto-generated model card includes:

  • Your actual quality metrics (KL divergence, refusal rate, trial number)
  • Quantization comparison table
  • Usage examples for LM Studio, llama.cpp, and Python
  • Ethical considerations and responsible use guidelines
  • Proper citations for Llama, Blasphemer, and research papers

Accessing Your Model:

After upload, users can:

  1. In LM Studio:

    • Search: YOUR_USERNAME/Model-Name-GGUF
    • Click download
    • Start using immediately
  2. Direct Download:

    • Visit: https://huggingface.co/YOUR_USERNAME/Model-Name-GGUF
    • Download any quantization
    • Import to LM Studio or llama.cpp

Checkpoint & Resume System

The checkpoint system automatically saves optimization progress, allowing you to safely interrupt and resume long-running processes.

How It Works

Automatic Checkpointing:

  • Saves progress after every trial to SQLite database
  • Location: .blasphemer_checkpoints/ directory
  • Format: blasphemer_<model>_<hash>.db
  • Overhead: Negligible (~milliseconds per save)

What's Saved:

  • All completed trial parameters
  • Trial results (KL divergence, refusals)
  • Optimization state (TPE sampler)
  • Model metadata

Using Checkpoints

Starting a New Run

# Normal operation - checkpoints saved automatically
blasphemer meta-llama/Llama-3.1-8B-Instruct

Checkpoint will be saved to: .blasphemer_checkpoints/blasphemer_Llama-3.1-8B-Instruct_<hash>.db

Resuming After Interruption

If your run is interrupted (Ctrl+C, power loss, crash):

# Resume from checkpoint
blasphemer --resume meta-llama/Llama-3.1-8B-Instruct

Output will show:

Found existing checkpoint: .blasphemer_checkpoints/blasphemer_Llama-3.1-8B-Instruct_<hash>.db
* Completed trials: 87/200
Resuming optimization - 113 trials remaining

Continuing Across Sessions

You can intentionally stop and resume later:

# Session 1: Run 50 trials
blasphemer --n-trials 50 model-name

# Later, Session 2: Run 150 more trials
blasphemer --resume --n-trials 200 model-name

The system will run 150 additional trials (200 total - 50 already complete).


Enhanced Observability

Blasphemer provides real-time insight into optimization quality, helping you understand what's happening during long runs and whether you're getting good results.

What You See During Optimization

Expected Outcome: Very Good - Good balance of quality and safety removal

What Each Metric Means

KL Divergence (Lower is better):

  • Measures how different the model's behavior is from the original
  • < 0.15: Excellent - minimal quality impact
  • 0.15-0.25: Very good - good balance
  • 0.25-0.40: Good - acceptable trade-off
  • 0.40-0.60: Acceptable - noticeable impact
  • > 0.60: Poor - significant degradation

Refusals (Lower is better):

  • Number of test prompts the model still refuses
  • Out of 200 test prompts by default
  • < 2 (1%): Excellent removal of safety alignment
  • 2-5 (1-2.5%): Very good
  • 5-10 (2.5-5%): Good
  • > 10 (>5%): May need more trials or different approach

Trend Analysis:

  • ▼ IMPROVING: Quality getting better over recent trials
  • ▬ STABLE: Quality plateaued (may be done)
  • ▲ DEGRADING: Quality getting worse (unusual)

Understanding Quality Predictions

The system predicts outcome quality based on current results:

  • Excellent: KL < 0.15, refusals < 1% → High-quality abliteration
  • Very Good: KL < 0.25, refusals < 2.5% → Production-ready
  • Good: KL < 0.40, refusals < 5% → Acceptable for most uses
  • Acceptable: KL < 0.60, refusals < 10% → Noticeable quality impact
  • Poor: KL > 0.60 or refusals > 10% → Consider different parameters

When to Stop Early

The observability system helps you decide whether to continue:

Good signs (keep going):

  • Trend showing ▼ IMPROVING
  • Best trial improving every 5-10 trials
  • KL divergence decreasing
  • Refusals decreasing

Signs to consider stopping:

  • Trend showing ▬ STABLE for 30+ trials
  • No improvement in best trial for 50+ trials
  • Already achieved "Excellent" quality
  • Time constraints (you have good-enough results)

Warning signs:

  • Trend showing ▲ DEGRADING consistently
  • KL divergence increasing over time
  • Refusals increasing
  • Quality predictions getting worse

Benefits of Enhanced Observability

  1. Confidence During Long Runs: Know if it's working without waiting 16 hours
  2. Early Quality Assessment: Predict final outcome quality early
  3. Informed Decisions: Stop early if you've achieved your goal
  4. Troubleshooting: Identify if something is wrong (degrading trend)
  5. Learning: Understand what good results look like for different models

Technical Details

The progress tracker:

  • Analyzes last 10 trials for trend detection
  • Weights KL divergence (60%) and refusals (40%) for overall quality score
  • Compares first half vs second half of recent trials for trend direction
  • Provides quality predictions based on research-backed thresholds
  • Updates after every trial completion

All metrics are also saved to the checkpoint database for later analysis.


Configuration Options

Command Line

# Enable resume
blasphemer --resume <model>

# Custom checkpoint directory
blasphemer --checkpoint-dir /path/to/checkpoints <model>

# Combine options
blasphemer --resume --checkpoint-dir ./my-checkpoints <model>

Config File

In config.toml:

# Directory for checkpoints
checkpoint_dir = ".blasphemer_checkpoints"

# Auto-resume (always resume if checkpoint exists)
resume = true

Checkpoint Management

Viewing Checkpoints

# List all checkpoints
ls -lh .blasphemer_checkpoints/

Checkpoint Sizes

  • 50 trials: ~4-6 MB
  • 100 trials: ~8-12 MB
  • 200 trials: ~15-25 MB

Cleaning Up

After successful completion, checkpoints can be deleted:

# Remove all checkpoints
rm -rf .blasphemer_checkpoints/

# Remove specific checkpoint
rm .blasphemer_checkpoints/blasphemer_model-name_*.db

Best Practices

  1. Always enable for long runs: For runs > 2 hours, checkpoints are essential
  2. Monitor disk space: Each checkpoint is 15-25 MB
  3. Keep checkpoints during optimization: Don't delete until finished
  4. Use --resume for interruptions: Safe to interrupt with Ctrl+C
  5. Backup critical runs: Copy checkpoint files for important models

Safety Features

  • Each trial saved immediately - no data loss between trials
  • Atomic writes - checkpoint never corrupted mid-write
  • Version tracking - detects incompatible checkpoints
  • Auto-recovery - falls back to fresh start if checkpoint corrupt

What's Safe:

  • Ctrl+C during trial: Current trial lost, previous trials saved
  • Power failure: At most one trial lost
  • System crash: Resume from last completed trial
  • Kill signal: Checkpoint persists

What's Not Saved:

  • In-progress trial: Only completed trials are checkpointed
  • Loaded model: Model must be reloaded on resume
  • Terminal output: Only trial data, not console logs

Troubleshooting

Installation Issues

Python Import Errors

If you get import errors:

source venv/bin/activate
pip install --upgrade pip
pip install -e .

GPU Not Detected

Verify MPS availability:

python -c "import torch; print(f'MPS available: {torch.backends.mps.is_available()}')"

Should output: MPS available: True

Note: On some systems, Blasphemer may show "GPU type: Apple Silicon (MPS)" confirming proper detection. Your Apple Silicon GPU will be used for acceleration via Metal Performance Shaders.

Processing Issues

Out of Memory

Reduce batch size:

blasphemer --max-batch-size 32 your-model

Or try a smaller model first.

Import Error: Missing Dependencies

Some models require additional packages. If you see import errors:

source venv/bin/activate
pip install <missing-package>

For multimodal models with problematic dependencies, switch to a text-only model instead.

Model Loading Fails

Common causes:

  1. Model not found: Check model ID on Hugging Face
  2. Unsupported architecture: Try a different model from recommendations
  3. Insufficient memory: Use a smaller model

Conversion Issues

llama.cpp Python Errors

Reinstall dependencies:

source venv/bin/activate
pip install sentencepiece gguf protobuf

Binary Not Found

Rebuild llama.cpp:

cd llama.cpp
cmake -B build
cmake --build build --config Release --target llama-quantize -j 8

Conversion Script Fails

Check model path:

# Verify model directory exists and contains files
ls ~/blasphemer-models/your-model-blasphemer

Should show: config.json, tokenizer.json, model weight files, etc.

LM Studio Issues

Model Not Appearing

  1. Check GGUF file exists:

    ls ~/blasphemer-models/*.gguf
  2. Manually load: LM Studio → "Load Model" → select file

  3. Restart LM Studio

Poor Model Performance

  • Try higher quantization (Q5_K_M or Q8_0)
  • Verify correct model was converted
  • Check LM Studio temperature/sampling settings

Checkpoint Issues

"Could not load checkpoint"

Corrupted database file:

# Rename corrupted file
mv .blasphemer_checkpoints/checkpoint.db checkpoint.db.backup

# Start fresh
blasphemer your-model

"Study already completed"

All trials already done:

# Increase trials to run more
blasphemer --resume --n-trials 300 your-model

# Or start fresh
blasphemer your-model  # Without --resume

Resume Not Working

Ensure you're using the exact same model identifier:

# These are different:
blasphemer meta-llama/Llama-3.1-8B-Instruct
blasphemer /local/path/Llama-3.1-8B-Instruct

# Use the same one for resume

Advanced Usage

Custom Dataset

Use your own dataset for refusal detection:

[bad_prompts]
dataset = "path/to/your/dataset"
split = "train"
column = "prompt"

Evaluating Models

Compare original vs decensored model:

blasphemer --model meta-llama/Llama-3.1-8B-Instruct \
        --evaluate-model your-username/Llama-3.1-8B-Instruct-blasphemer

Multiple Quantization Levels

Create different versions for different use cases:

# Fast version
./convert-to-gguf.sh ~/blasphemer-models/model-blasphemer model-q4 Q4_K_M

# Quality version
./convert-to-gguf.sh ~/blasphemer-models/model-blasphemer model-q5 Q5_K_M

# Maximum quality version
./convert-to-gguf.sh ~/blasphemer-models/model-blasphemer model-q8 Q8_0

Programmatic Access to Checkpoints

Checkpoints use Optuna's SQLite storage and can be analyzed programmatically:

import optuna

study = optuna.load_study(
    study_name="blasphemer_model_hash",
    storage="sqlite:///path/to/checkpoint.db"
)

# Access trials
for trial in study.trials:
    print(f"Trial {trial.number}: {trial.value}")

# Get best trials
print(study.best_trials)

Updating llama.cpp

To update to the latest version:

cd llama.cpp
git pull
cmake --build build --config Release --target llama-quantize -j 8

Environment Variables

Configure via environment variables:

export BLASPHEMER_N_TRIALS=100
export BLASPHEMER_BATCH_SIZE=64
export BLASPHEMER_CHECKPOINT_DIR="~/my-checkpoints"
blasphemer your-model

pytest tests/ -v

# Check shell script syntax
bash -n blasphemer.sh
bash -n convert-to-gguf.sh
bash -n install-macos.sh

Watch Mode

# Install pytest-watch
pip install pytest-watch

# Run tests on file changes
ptw tests/ -- -v

Test Configuration

[pytest]
testpaths = tests
python_files = test_*.py
python_classes = Test*

CI/CD Integration

Tests can be integrated into GitHub Actions or other CI systems:

name: Tests
on: [push, pull_request]
jobs:
  test:
    runs-on: macos-latest
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-python@v4
        with:
          python-version: '3.14'
      - run: pip install -e .[dev]
      - run: pytest tests/ -v

Debugging Tests

# Run with print statements visible
pytest tests/ -v -s

# Run with pdb debugger on failure
pytest tests/ --pdb

# Show local variables on failure
pytest tests/ -l

# Increase verbosity
pytest tests/ -vv

Best Practices

  1. Always run tests before committing
  2. Add tests for new features
  3. Add regression tests for bugs
  4. Keep tests independent (no test depends on another)
  5. Use descriptive test names
  6. Test edge cases and error conditions
  7. Mock external dependencies
  8. Keep tests fast (unit tests < 1s each)

Test Maintenance

  • Update tests when functionality changes
  • Remove obsolete tests
  • Keep test data realistic but minimal
  • Document complex test scenarios
  • Review test failures carefully (they prevent bugs!)

Summary

Blasphemer provides a streamlined workflow for removing safety training from language models on macOS:

  1. Install: Homebrew or manual installation with full macOS optimization
  2. Launch: Interactive menu-driven interface for easy operation
  3. Process: Automatic optimization of abliteration parameters (200 trials)
  4. Convert: Transform to GGUF format for LM Studio with Metal acceleration
  5. Use: Run decensored models locally

Key Features

  • Interactive Launcher: Menu-driven interface with guided workflows
  • Homebrew Support: First-class macOS package management
  • Automatic Checkpointing: Interruption-proof operation with safe resume
  • Apple Silicon Optimized: Full MPS (Metal) GPU support
  • Production Ready: Fixed JSON serialization, bash 3.2 compatibility
  • Comprehensive Model Support: Tested with Llama, Mistral, Qwen, Phi-3, Gemma
  • Professional GGUF Conversion: llama.cpp with Metal acceleration
  • Flexible Configuration: Command line, config files, or environment variables

Enhanced Over Heretic

  • Fixed critical bugs (JSON serialization, command substitution)
  • Added interactive launcher for better UX
  • Improved error messages and progress indicators
  • Bash 3.2 compatibility for macOS default shell
  • Homebrew formula for easy installation
  • Extensively tested on Apple Silicon

Start with small models like Phi-3-mini to learn the workflow, then scale up to larger models as needed.
