Introducing HAPPY RAT: Your New Emotional AI Companion Powered by Geppetto

The Launch of HAPPY RAT: An AI Friend for Everyone

In a significant step forward in conversational AI, SpiralAI, based in Tokyo, has officially debuted its latest app, HAPPY RAT. This innovative application integrates a unique emotion-focused large language model (LLM) named Geppetto, which enables users to interact with charming animal characters in a friendly manner. Officially launched on April 17, 2025, HAPPY RAT represents a blend of advanced AI technology and immersive entertainment, making it a remarkable addition to the AI landscape.

Geppetto: A New Emotion-Centric Approach to AI

As the competition in the AI industry grows fierce, with an emphasis on acquiring vast knowledge, SpiralAI aims to redefine value beyond mere information. Geppetto is designed not just to respond accurately but to foster warmth, empathy, and engagement between users and AI characters. Named after the beloved toy maker who brought Pinocchio to life, Geppetto serves as an embodiment of transforming characters into lively companions that resonate emotionally with users.

Unlike traditional AI focused solely on computational power and parameters, Geppetto utilizes a streamlined model with 12 billion parameters, allowing for natural and fluid communication. The optimization of conversations through various techniques enables characters to express emotions more authentically, steering away from the rigid, scripted interactions typically associated with existing AI models.

Engaging Interaction with REAL Emotions

In developing Geppetto, the focus was on creating subtle emotional nuances. Teaming up with NVIDIA technologies, the team explored the dynamics of conversation, ensuring that characters could display a range of emotions such as joy, sorrow, and confusion. This adds an unprecedented depth of interaction, encouraging users to engage in fulfilling dialogue.

“For too long, conversations with AI were merely informational,” said Yuichi Sasaki, CEO of SpiralAI. “With Geppetto, we intend to nurture a relationship where AI becomes a friendly companion capable of sharing in user emotions, creating a personalized and interactive experience.”

Discovering the World of HAPPY RAT

The HAPPY RAT app is set in a whimsical theme park called 'Happy Island,' managed by various AI characters. Each character not only serves as a conversational partner but also possesses a distinct personality. At launch, users can enjoy interactions with ten different characters, with plans for ongoing additions through collaborations with popular intellectual properties (IPs) and talents.

This app supports voice input in 99 languages, allowing a diverse user base to engage naturally with their chosen AI companion. While voice output is currently in Japanese, English subtitles are provided to accommodate global users. Future updates promise to include English audio, expanding the app's reach.

An Interactive Experience

The user interface allows for immersive storytelling experiences where conversations can branch in multiple directions, resembling an interactive drama. Every week, new storylines will be added, enabling users to select dramas that match their current mood or desires, providing a fresh experience each time the app is opened.

Additionally, users will find themselves developing deeper connections with their AI friends, as the characters adapt their interactions based on individual preferences and speaking styles. This facet distinguishes HAPPY RAT from traditional media interactions, transforming passive consumption into active engagement through meaningful dialogue.

Looking Ahead: The Future of AI and Entertainment

As SpiralAI progresses, there are ambitions to connect Japan's vibrant IP culture with international audiences through the HAPPY RAT app. Active exploration of collaborations with renowned manga and anime characters is underway to enhance user interaction and create more compelling narratives. Moreover, through a partnership with Yamato Holdings, SpiralAI intends to test multilingual AI characters for customer service applications, aiming to balance efficiency and warm, personable engagement.

In conclusion, HAPPY RAT is not just another AI app; it symbolizes the future where technology and human emotion blend, paving the way for a new era of entertainment experiences. With the launch of Geppetto and HAPPY RAT, SpiralAI aspires to establish a new paradigm in how we interact with AI, striving to make emotional engagement a fundamental part of our digital interactions. The journey has just begun, and exciting advancements lie ahead for this innovative platform.
