THE MORNING session of the TT Internet Governance Forum (TTIGF) on January 31 was supposed to be an online discussion of cyberbullying, but it turned into something else entirely.

According to Raj Ramdass, director of Restore a Sense of I Can (RSC), a Penal-based technology learning initiative, "The original set-up involved multiple moderators and student panellists from different schools engaging in discussions with the AI avatar on cyberbullying, making it more of a dialogue than just a Q&A session. After the discussions, students were supposed to move into breakout rooms for a more in-depth Q&A."

Sketchy school internet forced an adaptation of that plan and a single moderator, UWI student Danara Sahadeo, hosted the session, which quickly became a proof of concept of an app developed by RSC students, led by Inshan Bhattan, a former tech club member who now coaches development teams.

The custom AI tool is driven by a locally trained large language model and was demonstrated using a web-based 3D avatar to humanise the interface.

The technology is also being used to develop customised, regionally relevant AI tutors.

RSC has already released one that is teaching CSEC Mathematics Paper II and includes videos describing math procedures. Ramdass explained that in its earliest form, users can expect 90 per cent accuracy in its responses to questions.

Responding to questions from Guyana, where he was evangelising tech clubs last week, Ramdass explained that the humanoid model was initially created in 2021 for the Caribbean Association of Principals of Secondary Schools conference as part of an immersive virtual environment to assist teaching during covid19 lockdowns.

"Since then, we have been expanding that concept into AI-powered avatars. The avatar's appearance, background, and personality vary based on the specific application, though for all beta versions so far, we have primarily used just two core models."

One of those, a vaguely Asian, determinedly non-threatening female figure with a propensity for looking at her virtual hands, presented answers to questions about cyberbullying posed by students during the TTIGF online session.

Behind the scenes of the cyberbullying awareness app are several technologies, including speech recognition and synthesis, lip-sync animations, spatial awareness, a database, and multiple LLMs.

"The model configuration depends on factors like internet connectivity, device capabilities, confidentiality requirements, and the specific application," Ramdass said.

"If the avatar is acting as a panellist on stage, we use a quantised LLM to ensure low-latency responses. If it's functioning as a maths tutor, we integrate a fine-tuned LLM-trained specifically for that subject."

The cyberbullying resource is available to teachers who request it. RSC offers both a mobile app and a desktop version and there's a web version of t
