Lex Llama
A Gen AI-powered gym chatbot that helps you stay committed to your gym goals.
Having a hard time sticking to your gym resolutions? Meet Lex Llama. Ask him about training, programming or motivation, and he will not accept your excuses.
Here is how I built him. I created the training dataset with synthetic data generation, then finetuned the model on Hyperstack GPUs using parameter-efficient LoRA with 4-bit quantization, which cuts both training time and GPU costs.
The finetuned model is deployed with vLLM on Runpod serverless. The GPU scales to zero between visitors, so hosting costs nothing while nobody is chatting and a typical reply costs about a cent.
