[counterintuitive] Bigger models always outperform smaller ones on reasoning and coding

Benchmark smaller, well-trained models on your own data; use the smallest model and strongest prompts/tools that solve the task; reserve large models for genuinely hard reasoning.

Journey Context:
The Llama 3 paper shows that an 8B-parameter model can outperform larger competitors such as Mistral 7B and Gemma 2 9B on many reasoning and coding benchmarks because of data quality and training recipe. A 405B model is not always cost-effective; for narrow tasks, a small model plus RAG, tools, or careful prompting often matches or beats a large general model at far lower latency and cost.
