Summary

Anthropic's Science of Scaling team, led by Ted Moskovitz, focuses on empirically transforming compute into smarter AI models, emphasizing scientific rigor and epistemic humility in experimentation. The team measures AI acceleration not by benchmarks, but by "counterfactuals" – the reduction in human interventions required, noting significant trust shifts with models like Opus 4.5 and Mythos-class. Anthropic observes that over 80% of its codebase is Claude-authored, with engineers merging eight times more code daily and kernel optimization speedups increasing from 3x to 52x in under a year. Moskovitz argues larger models can be more cost-effective due to fewer tokens needed for equally good answers. The team also explores "taste" in AI research, with models like Mythos showing improved judgment, and views safety as a core capability, not a cost, citing reinforcement learning from human feedback as a prime example.

Key takeaway

For AI Scientists and Machine Learning Engineers evaluating model development strategies, you should adopt a rigorous, empirical approach to scaling, focusing on reducing human intervention as a key metric for AI acceleration. Prioritize experiments with clear cost-benefit analyses to optimize compute allocation. Recognize that larger, more capable models can often be more cost-effective than smaller ones, and integrate safety research as a core capability driver, not a separate overhead.
