About koodos labs
koodos labs is a consumer AI research and product company dedicated to ensuring that the internet knows you and can do things for you, on your terms. We are the company behind Shelf, the leading personal context platform used by millions of people to track and understand what they consume. Read about the co-founders and their story here.
About Mozilla.ai
Mozilla.ai is the Mozilla's new AI company building open source AI that works for people, not on them. Led by Prof John Dickerson.
The opportunity
AI models get evaluated on everything except the thing that matters most for truly personalized AI: do they actually understand you? There is no standard benchmark for how well a system can build a coherent model of a person from the full stack of user signals. Nobody has formally characterized that structure. So nobody can measure progress against it. And because the modeling happens inside closed platforms, the people being represented have no visibility into how they are represented.
No agreed taxonomy. No methodology for how signals compound into a holistic representation of you.
Your primary deliverable is a publishable benchmark: a rigorous, reproducible eval framework for user understanding across signal types.
The work
Part 1: Formalize the structure of a user profile. Characterize the taxonomy of signals that make up a person's identity to an AI system. Build on our current taxonomy to test the structure's coverage and accuracy against real user data; Shelf has millions of users with aggregated cross-category data. Identify where it over-specifies, where it under-specifies, where inferences systematically fail. Ultimately, this’ll become the core representation of a user’s identity and taste to AI systems.
Part 2: Design and measure gap-aware collection. A structure that tells you which data would be most valuable to collect next drives a compounding loop. Identify gap, surface a prompt, collect the missing signal, update the profile, repeat.
Deliverables: a paper that can be built on for publication targeting RecSys, UMAP, NeurIPS, or adjacent; and an open-source contribution for a user understanding benchmark.
Relevant prior art
Who we're looking for
Post-doc, PhD or graduate student in ML, NLP, information retrieval, recommender systems, cognitive science, HCI, or adjacent
You've read the MMLU paper, have a view on why PersonaMem was built the way it was and what it misses, and can tell us what makes an eval stick
Comfortable on the conceptual side (is the profile structure carving reality at the joints?) and the technical side (dataset construction, eval pipelines, baselines against current models)
