What happened
This Latent Space piece argues that since 2022, one component of the ML pipeline per year has flipped from human-made to model-made simulation—reward signals (InstructGPT/Constitutional AI), training data (Phi series, Apple WRAP, NVIDIA Nemotron-4), and teachers (Alpaca's $600 fine-tune)—each trading ~10% quality loss for 100x cost reduction and 10,000x speedup. It frames 'synthetic data' and 'AI researcher' as increasingly ambitious human simulation that becomes load-bearing at frontier labs before industrializing.
Why it matters
If you build with or on AI, the shift to simulation-based pipelines means you should evaluate whether your own data, eval, and fine-tuning workflows still justify human-in-the-loop costs—or whether LLM-generated data, rubrics, and judges are now 'good enough' at a fraction of the cost. The Phi and WRAP results suggest even small teams can synthesize textbook-quality corpora and rephrased web data to train or fine-tune competitively, rather than buying or labeling datasets.
Discussion angle
Which part of your current AI pipeline—eval rubrics, training data, or fine-tuning teachers—is still human-made, and what would it cost (and risk) to replace it with simulation this quarter?
