By PulseAugur Editorial · [1 sources] ·

A Year 11 student developed an AI companion app called Soulor AI, utilizing a fine-tuned Qwen3 14B model. The development process highlighted several key challenges and solutions, including ensuring the model's output matched the required JSON format for the app's frontend, optimizing latency by moving to an NVIDIA H100 GPU, and implementing a gateway to manage cold starts for the scale-to-zero serverless endpoint. The student also identified and fixed two underlying bug patterns that caused seemingly unrelated outages. AI
