Scale AI Data Engine for Supervised Fine-Tuning & RLHF at Scale

Engineered human-in-the-loop expert annotation pipelines generating multi-million token pairs of complex instruction following, code review, and preference datasets powering the training of leading open and commercial models.

Model & Execution Context:Distributed annotation platforms with automated inter-annotator agreement metrics and synthetic validation loops.

Scope & Limitations

Human expert verification costs scale super-linearly with problem complexity in post-doctoral mathematics and legal reasoning.

SEAL Leaderboards: Standardized Private Evals for Frontier LLM Benchmarking

Created the SEAL evaluation platform providing contamination-free, expert-curated benchmark suites testing advanced programming (Coding-GSM), mathematical rigor, and adversarial safety to combat public leaderboard gaming.

Model & Execution Context:Private held-out dynamic evaluation testbeds continuously updated by human domain experts.

Scope & Limitations

Requires ongoing prompt refresh cycles to prevent indirect test data leakage into web-crawled pretraining corpora.
