# Deliberation-Outerlinks

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

We introduce **RecursiveMAS**, a multi-agent framework that scales agent collaboration through **latent-space recursion**. RecursiveMAS 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 **Deliberation-Style** setting, the Reflector Agent and Tool-Caller Agent collaborate through Outer RecursiveLink modules for iterative reasoning, tool-oriented execution, and refinement.

## Model Details

| Item | Description |
|---|---|
| Model | Deliberation-Outerlinks |
| Collaboration Style | Deliberation-Style |
| Component Role | Outer RecursiveLink Modules |
| Reflector-Toolcaller-Outerlink.pt | Reflector Agent → Tool-Caller Agent |
| Toolcaller-Reflector-Outerlink.pt | Tool-Caller Agent → Reflector Agent |

⚠️ **Note:** This checkpoint contains **Outer RecursiveLink modules** for [**RecursiveMAS**](https://arxiv.org/abs/2604.25917), rather than a standalone model intended for plain-text generation.  

## Sample Usage

To load the full Deliberation-Style system using these modules, you can use the high-level API provided in the [official repository](https://github.com/RecursiveMAS/RecursiveMAS):

```python
from system_loader import load_mas_system

# Load the deliberation style multi-agent system
mas = load_mas_system(
    style="deliberation",
    device="cuda",
    trust_remote_code=True,
)

reflector = mas.agents["reflector"].model
toolcaller = mas.agents["toolcaller"].model
```

For detailed execution commands on downstream tasks, please refer to the [GitHub repository](https://github.com/RecursiveMAS/RecursiveMAS).
