# Mixture-Summarizer-Qwen3.5-2B
[🌐 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 introduced in [Recursive Multi-Agent Systems](https://huggingface.co/papers/2604.25917) 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 **Mixture-Style** setting, this **Summarizer Agent** integrates outputs from domain-specialized agents and produces the final response through recursive latent-space collaboration.
## Model Details
| Item | Description |
|---|---|
| Model | Mixture-Summarizer-Qwen3.5-2B |
| Collaboration Style | Mixture-Style |
| Agent Role | Summarizer Agent |
| Base Model | Qwen3.5-2B |
⚠️ **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 agent as part of the RecursiveMAS pipeline, you can load the system using the provided loader from the [official repository](https://github.com/RecursiveMAS/RecursiveMAS):
```python
from system_loader import load_mas_system
# Load the whole Mixture-Style MAS pipeline
mas = load_mas_system(
style="mixture",
device="cuda",
trust_remote_code=True,
)
# Access the specific summarizer model
summarizer = mas.agents["summarizer"].model
```
