# dirlora-v3

`dirlora-v3` is a LoRA-adapted model checkpoint built for concise, instruction-style text embedding with
aware of previous text and following text.

## Model details
- **Model type:** Causal Language Model (LoRA adapter)
- **Base model:** `Qwen/Qwen3-Embedding-0.6B`
- **Fine-tuning method:** LoRA / PEFT
- **LoRA config:**
  - Rank (`r`): `16`
  - Alpha (`alpha`): `{{alpha}}`
  - Dropout: `{{lora_dropout}}`
- **Training data:** subset of `wikitext 103` for PoC
- **Framework:** PyTorch + Hugging Face `transformers` + `peft`

## Intended use
Use this model for:
- text embedding
- experimenting direction/sequence aware embedding

## Not intended for
- any engineering solution

## Usage

```python
from sentence_transformers import SentenceTransformer

model = SentenceTransformer("npc0/Qwen3-Embedding-0.6B-OED")

sentences = [
    "The weather is lovely today.",
    "It's so sunny outside!",
    "He drove to the stadium."
]
embeddings = model.encode(sentences)

similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
```
## Limitations

- This is early stage PoC not converged but made progress comparing to previous versions
