# Instruction Residuals

This repository contains instruction residuals (delta weights) computed as the parameter-wise difference between `ibm-granite/granite-4.0-h-tiny` and `ibm-granite/granite-4.0-h-tiny-base`.

Apply these residuals to the base model to reconstruct the instruction-tuned weights without retraining.


## Usage

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
from residuals import Residuals

base = AutoModelForCausalLM.from_pretrained("ibm-granite/granite-4.0-h-tiny-base")
tok = AutoTokenizer.from_pretrained("ibm-granite/granite-4.0-h-tiny-base")

res = Residuals.from_pretrained("residuals/granite-4.0-h-tiny")
res.apply(base, base_tokenizer=tok)
```

## Files
- **model.safetensors**: Serialized residual tensors (safetensors format).
- (optional) **model.safetensors.index.json** + shard files `model-00001-of-000N.safetensors`, ... for multi-part weights.
- **config.json**: Residuals metadata and provenance.
- **tokenizer files**: Saved tokenizer for compatibility.

## About this format
These are additive residuals (task vectors). Applying them to the base model's parameters reconstructs the instruction-tuned model.

## Tools
Generated with the `residuals` Python package. Install via: `pip install residuals`.
