Developing a Custom LLM Model for Kids Education

Solution

To complete this project, we assigned a vetted AI/ML developer with years of experience in delivering projects for businesses of all sizes and diverse industries. 

The project began with the data collection phase. Our developer collaborated with experts on the client’s side to identify and collect high-quality, age-appropriate learning materials. This included academic texts, child-friendly FAQs, and interactive exercises. Additionally, synthetic data generation with anonymized real-world queries was also incorporated. 

Next, our developer moved to model training and evaluation. They leveraged open-source LLM architectures and fine-tuned the model to understand and respond in a manner aligned with children’s comprehension levels and emotional sensitivity.  The evaluation process included both automated metrics and human-in-the-loop testing, where educators reviewed the chatbot’s responses for clarity, engagement, and pedagogical value.

The model was deployed using Amazon Bedrock, and used the LoRA (Low-Rank Adaptation) technique to efficiently train a custom LLM tailored to our domain with minimal resource overhead. This allowed for scaling quickly while keeping infrastructure costs in check. LoRA enabled injecting domain-specific behaviors without altering the base model architecture, ensuring a lightweight, maintainable solution.

The system was built to support ongoing improvements and future iterations, including multi-language support and gamified learning features.tem accordingly, and developed effective recovery strategies.
