Amanda Askell
Leads Anthropic's Character work (finetuning and AI alignment), Anthropic
Amanda Askell is a philosopher working on finetuning and AI alignment at Anthropic, where Askell's team trains models to be more honest and to have good character traits. Anthropic credits Askell as the lead of its Character work and the primary author of Claude's constitution, released in January 2026 under a CC0 1.0 deed. Before Anthropic, Askell was a research scientist on OpenAI's policy team, working on AI safety via debate and human baselines for AI performance, and is a co-author of the GPT-3 and CLIP papers. Askell is also first author of Anthropic's 2021 paper "A General Language Assistant as a Laboratory for Alignment".123456

Career
Amanda Askell's CV lists doctoral study in philosophy at New York University from 2011 to 2018, with a thesis on Pareto principles in infinite ethics advised by Cian Dorr, and an earlier BPhil at the University of Oxford with a thesis on objective epistemic consequentialism. Askell's philosophical work has centered on ethics, decision theory, and formal epistemology.71
From 2018 to 2021 Askell was a research scientist on the policy team at OpenAI, working on AI safety via debate and on human baselines for AI performance. Askell joined Anthropic in 2021 as a research scientist in alignment finetuning, and Anthropic now credits Askell with leading its Character work.712
Research
From 2019 to 2021, Askell's publications included work on AI safety and social science, release strategies for language models, and cooperation in responsible AI development, along with co-authorship of the GPT-3 paper in 2020 and the CLIP paper in 2021.8459
At Anthropic, Askell was the first author of "A General Language Assistant as a Laboratory for Alignment" in December 2021 and co-authored later papers including Constitutional AI (2022), work on moral self-correction in language models (2023), and studies of sycophancy and of specific versus general principles for constitutional AI (2023). Askell's team trains models to be more honest and to have good character traits, and develops finetuning techniques meant to scale to more capable models.681
