# RWKV-Seed-OSS-36B-hxa079

**Acknowledgment**

This project received computational resources and technical support from **Recursal.AI**. I'm deeply grateful for their support!

This is an experimental model that converts most of the Transformer LLM to RWKV linear attention based on the **RADLADS** method.

## Model Overview

* **Model Name:** RWKV-Seed-OSS-36B-hxa079
* **Architecture:** RWKV “hxa079+” hybrid — RWKV-Attention strategically interleaved with NoPE FullAttention
* **Base Model:** ByteDance-Seed/Seed-OSS-36B-Instruct
* **Model Revision:** alpha
* **Parameters:** ~37.1B
* **Context Window (Passkey):** 130k

---

## Architecture Details

* **RWKV Layers:** Interleaved RWKV blocks based on the `hxa079` design
* **Transformer Layers:** Placed at strategic depths to enhance long-context performance
* **Hybrid Design:**

  * RWKV provides temporal decay and efficient recurrent-style state handling
  * NoPE (No Positional Embedding) FullAttention augments global reasoning without redundant positional encoding
* **LoRA Customization:**

  * Rank Decay: 448
  * ICLR: 192
  * Value Residual Mix: 128
  * Key Residual Mix: 128
  * Gate: 576
* **RoPE Usage:** Enabled (`use_rope: true`), aligning positional encoding with RWKV blocks

## Key Hyperparameters

* Hidden Size: 5120
* Intermediate Size: 27,648
* Head Dimension: 128
* Attention Heads: 80
* Key/Value Heads: 8
* Hidden Layers: 64
* Max Position Embeddings: 524,288
* Activation: SiLU
* Dropout: 0.1 (residual & attention)
* Bias: Disabled for MLP & Attention Output

## Evaluation

Performance evaluation is ongoing. The model shows promising results in:
-   Maintaining base model capabilities while achieving linear attention efficiency
-   Significantly improved needle-in-haystack task performance compared to pure RWKV architectures
-   Competitive performance on standard language modeling benchmarks
-   mmlu: 78.39%(Base 82.41%)
-   gsm8k: 86.88%(Base93.93%) with gentoken=2048
-   passkey 130k+(Base 500k)

## Usage with Hugging Face Transformers

need install flash-linear-attention
```bash
pip install flash-linear-attention
```

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "OpenMOSE/RWKV-Seed-OSS-36B-hxa079"

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto",
    trust_remote_code=True,
)

tokenizer = AutoTokenizer.from_pretrained(model_name)

prompt = """There is a very famous song that I recall by the singer's surname as Astley.
 I can't remember the name or the youtube URL that people use to link as an example url.
 What's song name?"""
messages = [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": prompt},
]
text = tokenizer.apply_chat_template(
    messages, tokenize=False, add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

generated_ids = model.generate(**model_inputs, max_new_tokens=512)
generated_ids = [
    output_ids[len(input_ids) :]
    for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]

response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]

```
