The New Frontend Stack: Humans, AI, and Prompts
summary
Creates a React TypeScript invoice form and runs strict unit tests against several LLMs (Mistral, Code Llama, Gemini, Claude Sonnet), reporting initial pass 3/10 then rising to 9/10 after adding YAML with comments as a spec. Runs ~100 production experiments, finds smaller models plus structured specs outperform larger models (Gemini guesses, Claude Sonnet asks for clarification). Argues specs are for engineers not models, recommends React TypeScript invoice form examples and structured prompt discipline to get reproducible results.
