The pipeline from research paper to production model has dramatically accelerated. Early innovations like RLHFrlhfReinforcement Learning from Human Feedback — training models to align with human preferences by having humans rank outputs. took 5+ years to go mainstream. Now, architectures like Mamba go from paper to production in months. This compression is both exciting (faster progress) and concerning (less time for safety evaluation).
