# Latent Recurrent Depth Language Model

## Overview

The Latent Recurrent Depth Language Model (LRD-LM) is an experimental text-generation architecture designed to capture deeper contextual information through iterative, latent processing. Instead of generating verbose chain-of-thought sequences, LRD-LM refines its internal state over multiple recurrent iterations to improve text generation quality while keeping the parameter count modest.

## Architecture

The model is built around three key components:

- **Prelude Block:**  
  This block handles the initial processing by embedding input tokens and applying self-attention with positional encodings.

- **Recurrent Block:**  
  A core, weight-shared block that iteratively refines a latent state. By repeatedly processing the prelude output along with its own evolving state, the model effectively “thinks” over the input without outputting intermediate tokens.

- **Coda Block:**  
  The final block decodes the refined latent state into output token probabilities.

## Applications & Limitations

**Intended Uses:**
- **Text Generation:**  
  Generate creative text, dialogue, code, or other natural language content.
- **Research:**  
  Serve as a testbed for exploring novel architectures and techniques in language modeling.

**Limitations:**
- **Data Constraints:**  
  Trained on a small subset (first 1000 samples) of the Wikitext-2-raw-v1 dataset, which may limit its performance compared to models trained on larger corpora.
- **Performance:**  
  While it demonstrates the potential of latent recurrent depth, its overall performance is experimental and may not match state-of-the-art models.
- **Computational Overhead:**  
  The iterative processing introduces extra computation.
- **Bias:**  
  As with all language models, generated outputs may reflect biases present in the training data.

## Training Details

The model was fine-tuned on a subset of the Wikitext-2-raw-v1 dataset (first 1000 samples) using the AdamW optimizer and a cosine annealing learning rate scheduler. The training configuration and hyperparameters are provided in the accompanying code, and adjustments may be needed for improved performance.

## Usage

The model can be used for text generation via its integrated `generate()` method, which allows you to control parameters such as the maximum sequence length, number of recurrent iterations, temperature, and top‑k filtering.

### Example: Direct Inference

```python
from transformers import AutoModelForCausalLM, AutoTokenizer, AutoModel

# Load the model and tokenizer from the hub
model = AutoModelForCausalLM.from_pretrained("codewithdark/latent-recurrent-depth-lm")
tokenizer = AutoTokenizer.from_pretrained("codewithdark/latent-recurrent-depth-lm")

prompt = "In the realm of language modeling"
input_ids = tokenizer(prompt, return_tensors='pt').input_ids

# Generate logits using a specified number of recurrent iterations
logits = model(input_ids, num_iterations=3)

# Sample from logits to produce generated text
import torch
probs = torch.softmax(logits[:, -1, :], dim=-1)
next_token = torch.multinomial(probs, num_samples=1)
generated_ids = torch.cat([input_ids, next_token], dim=1)
generated_text = tokenizer.decode(generated_ids[0], skip_special_tokens=True)
clean_text = generated_text.replace('Ġ','')
print(generated_text)
```

### Alternative: Using the `generate()` Method

```python
from transformers import AutoTokenizer, AutoModel, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("codewithdark/latent-recurrent-depth-lm")
model = AutoModel.from_pretrained("codewithdark/latent-recurrent-depth-lm", trust_remote_code=True)

prompt = "In the realm of language modeling"
input_ids = tokenizer(prompt, return_tensors="pt").input_ids
generated_ids = model.generate(input_ids, max_length=50, num_iterations=10, temperature=0.5, top_k=50)
generated_text = tokenizer.decode(generated_ids[0], skip_special_tokens=True)
clean_text = generated_text.replace('Ġ','')
print(clean_text)

```
