# Sequential-Light-Solver-Qwen2.5-Math-1.5B
[🌐 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 Sequential-Light setting, the Solver Agent is responsible for producing the final response based on the planning and critique information refined through RecursiveLink modules.
## Model Details
| Item | Description |
|---|---|
| Model | Sequential-Light-Solver-Qwen2.5-Math-1.5B |
| Collaboration Style | Sequential-Light |
| Agent Role | Solver Agent |
| Base Model | Qwen2.5-Math-1.5B |
⚠️ **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.
For detailed usage instructions, please refer to our [GitHub repository](https://github.com/RecursiveMAS/RecursiveMAS).
## Usage
To use this agent as part of the RecursiveMAS framework, you can load the entire system using the following code from the official repository:
```python
from system_loader import load_mas_system
mas = load_mas_system(
style="sequential_light",
device="cuda",
trust_remote_code=True,
)
planner = mas.agents["planner"].model
critic = mas.agents["critic"].model
solver = mas.agents["solver"].model
```
