I’ve joined the AKI team at Apple as a Machine Learning Engineer to work on improving Apple Intelligence!
I am currently part of the LLM Summarizer team, focusing on post-training models using techniques like SFT, RL, and Prompt Optimization. I’m also heavily involved in reranking methods like listwise and pairwise learning. Super excited to be building and aligning state-of-the-art models here.
