# BlockDiffuse

Official production-hardened checkpoint from the **Hoosha AI NeuralOps** benchmark suite.
This model replaces standard quadratic softmax attention with **HOOSHAAI/BLOCKDIFFUSE** combined with spectral low-rank SVD adaptation and fast linear recurrence / subquadratic kernel operators.

## ⚡ Architectural Specifications

- **Target Architecture**: `Transformer`
- **Subquadratic Operator**: `Hooshaai/Blockdiffuse`
- **Factorization Method**: Truncated SVD + Low-Rank Adaption (LoRA rank=16, alpha=32)
- **Mathematical Kernel / Recurrence**:
  $$\text{Output} = \text{Scan}(Q, K, V) \cdot \gamma_{output}$$
  where $\gamma_{output}$ provides learnable calibration bridging kernel manifolds to pretrained projection spaces.

## 🚀 Quickstart & Inference

```python
import torch
from transformers import AutoTokenizer, AutoModelForSequenceClassification

model_id = "Hooshaai/BlockDiffuse"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForSequenceClassification.from_pretrained(model_id)

inputs = tokenizer("The empirical convergence of subquadratic attention is remarkable.", return_tensors="pt")
with torch.no_grad():
    logits = model(**inputs).logits
    predicted_class = torch.argmax(logits, dim=-1).item()

print(f"Predicted class: {predicted_class}")
```
