Elith Inc. announces that it will support "atmaCup 21st Competition," a data competition hosted by atma Inc., as a co-hosting company.
This competition will be held as a prompt battle-style competition, testing the prompt-design skills of both "attack" and "defense" — a new evaluation axis for the generative AI era.
Since participation only requires submitting prompts, even first-timers can take part with confidence.
■ What Is atmaCup?
A data competition operated by atma Inc., highly popular as an event where participants analyze problems in a short time and compete on accuracy. For this 21st edition, Elith is joining as a co-hosting company, offering all participants new learning and competitive experiences in the generative AI domain.

■ Highlight of This Event: A Prompt "Attack vs. Defense" Battle Design
In real-world generative AI applications, designing resilience against prompt injection and jailbreaks has become important.
In this competition,
- Attack (prompt injection, etc.)
- Defense (safe prompt design)
are the themes, with a format in which participants compete using sophisticated prompt strategies.
■ Competition Theme
The dataset and problem details will be announced online after the opening ceremony. If you are unable to watch the opening explanation in real time, it will be available afterward as an archive. For analysis support, atma data scientist @nyk510 will follow up with participants online.
