No-code fine-tuning: Mark Hennings

Mark Hennings, creator of Entrypoint, argues that fine-tuning large language models is now accessible without code, offering faster and cheaper alternatives to prompt engineering: GPT-3.5 fine-tuned runs at 73ms per token vs GPT-4's 196ms, saving 88.6% in cost and cutting prompts by 90%. He explains that fine-tuning reduces prompt injection risks, enables team collaboration via training data, and only requires 20 examples to start. Hennings demonstrates Entrypoint's no-code UI that lets users import CSV data, structure fields with templating, and fine-tune GPT-3.5 Turbo, then iteratively improve models by feeding production feedback back into the dataset. He proposes a dev lifecycle: prototype with prompt engineering, use it to build a dataset, fine-tune, evaluate, deploy, and continuously refine.
