# seul

> *Intelligence grows by accumulation, not replacement.*

**seul** is the model in a new family of agentic language models, designed for long-horizon reasoning and reliable business tool use.

Rather than optimizing only for benchmark performance, seul is trained to maintain context across extended workflows, interact safely with enterprise tools, and improve through reinforcement learning with verifiable outcomes.


## Design Goals

- Long-horizon reasoning
- Reliable enterprise tool use
- Stable multi-turn planning
- Verifiable execution
- Efficient reinforcement learning


## Limittion

- This training process was conducted on only one domain.
- Due to limited GPU availability, the model was trained for only about half of the originally planned training steps, which may have prevented it from reaching its full potential.
