Beat GPT 4 and Build the Best AI For You: Mobilizing First-Party Data with Fine-Tuning
summary
Claims that fine-tuning first‑party data lets teams beat off‑the‑shelf models with concrete wins: image classification shows 81% vs 95% when a tiny task‑specific model outperforms GPT‑4, Databricks fine‑tunes Llama 8b for code diffs and gets higher accuracy at far lower cost, and vendors report systems that go from ~50% to 98–99% by obsessively tuning pipelines. Runhouse builds CubeTrch to remove experimental escape velocity so fine‑tuning, embedding refreshes, and infra changes actually ship and improve production performance.
