Spencer Poff is an NLP engineer and product-minded technologist with 11 years of experience building production chatbots, ML infrastructure, and consumer-facing apps from startups to Meta/FAIR. Currently a Member of Technical Staff at Harvey, he previously tech-led chatbot teams at Meta contributing to the BlenderBot series and publications at ICLR, ICML, and EMNLP. He blends deep research sensibilities (Google Scholar presence) with hands-on engineering—debugging token-level loss in ParlAI and adding temperature decoding to improve generative outputs. A serial founder and builder, Spencer has launched AR field-service tooling and language-learning products, giving him a rare mix of product intuition and systems-level execution. Based in San Francisco, he pairs academic rigor with pragmatic product delivery, often surfacing subtle model-evaluation improvements that accelerate debugging and model iteration.

Nov 2019 - Aug 2022

A framework for training and evaluating AI models on a variety of openly available dialogue datasets.
Role in this project:
userBack-end Developer & ML Engineer
Contributions:88 reviews, 56 commits, 83 PRs in 2 years 9 months
Contributions summary:Spencer focused on debugging and improving the token-level loss calculations within the `parlai` framework. They added the ability to output and visualize token losses for generative models, aiding in debugging. Additionally, the user implemented and tested a new temperature decoding option within the `torch_generator_agent`, enhancing the model's output generation capabilities. Code changes are focused on model behavior, evaluation, and extending the core ParlAI functionality.
