# Sequential-Scaled-Critic-Llama3.2-3B

[🌐 Project Page](https://recursivemas.github.io) | [💻 Code](https://github.com/RecursiveMAS/RecursiveMAS) | [📄 Paper](https://arxiv.org/abs/2604.25917)

**RecursiveMAS** is a multi-agent framework that scales agent collaboration through **latent-space recursion**. It treats a multi-agent system as a unified recursive computation, where heterogeneous agents iteratively exchange, refine, and evolve their latent states across recursion rounds. 

In the **Sequential-Scaled** setting, this **Critic Agent** is responsible for reviewing and refining the initial plan produced by the Planner Agent, which is then passed to the Solver Agent for final solution generation.

## Model Details

| Item | Description |
|---|---|
| **Model** | Sequential-Scaled-Critic-Llama3.2-3B |
| **Collaboration Style** | Sequential-Scaled |
| **Agent Role** | Critic Agent |
| **Base Model** | [Llama-3.2-3B-Instruct](https://huggingface.co/meta-llama/Llama-3.2-3B-Instruct) |

⚠️ **Note:** This checkpoint is a **role-specific agent** in [RecursiveMAS](https://arxiv.org/abs/2604.25917), rather than a standalone model intended for plain-text generation. 

## Usage

To use this model within the RecursiveMAS framework, you can load the entire multi-agent system as follows:

```python
from system_loader import load_mas_system

# Load the whole MAS pipeline
mas = load_mas_system(
    style="sequential_scaled",
    device="cuda",
    trust_remote_code=True,
)

planner = mas.agents["planner"].model
critic = mas.agents["critic"].model
solver = mas.agents["solver"].model
```

For detailed setup and inference instructions, please refer to the [GitHub repository](https://github.com/RecursiveMAS/RecursiveMAS).
