Milestone (age 23)

Lead author of chain-of-thought prompting (arXiv Jan 2022) and earlier FLAN instruction-tuning paper (arXiv Sept 2021) while at Google Brain—field-defining LLM reasoning work at age ~23–24 (Dartmouth CS ’20; Fairfax County / TJHSST pipeline consistent with ~1998 birth).

Grew up Fairfax County, VA; competitive STEM high school path (TJHSST noted on LinkedIn). Dartmouth CS ’20 with Goldwater Scholarship (2019) for ML research; undergrad ML/health-care papers with Dartmouth faculty. Google Brain AI Resident from Oct 2020, then research scientist track producing FLAN and CoT.

Question four · where did the leverage come from?

Jason Wei's leverage provenance

Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Jason Wei's outcome attributable to any origin.

Luck is not a leftover score.

Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.

Within Researchers / independent engineers, Jason Wei's starting-advantage total is at the 20th percentile. Separately, their built or converted leverage total is at the 55th percentile. Other T2 profiles average 7.9 / 24 starting advantage and 12.3 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Evidence summary

Dartmouth News (2019 Goldwater), personal site, and arXiv establish timeline: undergrad → Brain residency (2020) → FLAN (2021) → CoT (2022) well before age 26. Education path strongly supports ~1998 birth (class of 2020). Later OpenAI reasoning/agents (2023–2025) and Meta Superintelligence Labs continue the arc. Family background not documented; leverage is institutional + technical depth on the LLM wave.
