Talking it out is underrated. Rubber duck debugging and peer programming are time-tested techniques for thinking clearly, catching bugs, and sparking new ideas. But when you’re coding alone, it’s easy to lose that habit — and with it, a lot of momentum. That’s where Cheerleader comes in: a free, open-source VSCode extension that brings an interactive AI coding companion right into your workspace.

This summer I had the incredible opportunity to build Facet AI as my Google Summer of Code project. Facet AI’s purpose is simple: democratize fine-tuning for small language models by turning complex, error-prone workflows into a polished, streamlined experience — from dataset formatting and augmentation to evaluation and deployment — so anyone can craft their own “facet” of Gemma, DeepMind’s open-source vision-language model.
