+
+**RADLADS** (Rapid Attention Distillation to Linear Attention Decoders at Scale) introduces a novel protocol for rapidly converting softmax attention transformers into linear attention decoder models. This highly efficient process requires only 350-700 million tokens of distillation, which is less than 0.005% of the token count used to train the original teacher models.
+
+This repository provides the **RADRWKV7Qwen2.5-7B** model, a converted version from Qwen2.5. The RADLADS approach maintains quality remarkably close to the original transformer while achieving state-of-the-art downstream performance for linear attention models of their size. It enables significantly faster inference due to its constant-time inference per token.

+
+## ✨ Key Highlights
+
+*   **Efficient & Cost-Effective Conversion**: Converts large softmax attention transformers to linear attention models with minimal additional training tokens. Converting a 72B model costs less than $2,000 USD.
+*   **Quality Preservation**: Models converted using RADLADS maintain quality remarkably close to the original teacher transformer models.
+*   **State-of-the-Art Performance**: These models achieve state-of-the-art downstream performance across standard benchmarks for linear attention models of their size.
+*   **Faster Inference**: Leverages linear attention for constant-time inference per token, significantly boosting decoding speed.
+*   **New Architectures**: Introduces new RWKV-variant architectures (RAD-RWKV6 and RAD-RWKV7) optimized for linear attention.
+
+## How to use
+
+This model is compatible with the Hugging Face `transformers` library. Ensure `trust_remote_code=True` is set when loading the model due to custom architecture components.
+
+### Text Generation
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+import torch
+
+model_name = "recursal/RADRWKV7Qwen2.5-7B" # This model
+
+# Load model and tokenizer
+model = AutoModelForCausalLM.from_pretrained(
+    model_name,
+    torch_dtype=torch.bfloat16, # or torch.float16 if needed
+    device_map="auto",
+    trust_remote_code=True
+)
+tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True, use_fast=False)
+
+# Prepare input
+text = "The quick brown fox jumps over the lazy"
+input_ids = tokenizer.encode(text, return_tensors="pt").to(model.device)
+
+# Generate text
+generated_ids = model.generate(
+    input_ids,
+    max_new_tokens=50,
+    do_sample=False, # Set to True for sampling, adjust temperature/top_p
+    eos_token_id=tokenizer.eos_token_id,
+    pad_token_id=tokenizer.eos_token_id, # Or set to a specific pad_token_id if available
+)
+
+# Decode output
+output_text = tokenizer.decode(generated_ids[0], skip_special_tokens=True)
+print(f"Input: {text}
+Generated: {output_text}")
+```
