AI research + knowledge systems

Marvin B. Freedman

AI Research Engineer — LLM knowledge, retrieval, and verification systems.

I build practical AI systems that help language models retrieve, remember, verify, and act on external knowledge. My work spans agent workflows, RAG-style retrieval, long-context memory, AI coding assistants, product chatbots, verification loops, and full-stack applications that turn ambiguous AI ideas into working systems. I study how language models fail when interacting with external knowledge — in retrieval ranking, context boundaries, verification signals, and long-horizon memory — and build systems to measure and fix those failure modes.

Anthropic Knowledge Team fit

External knowledge, retrieval, agentic search, and model reliability.

My strongest fit is building systems around LLMs that make external knowledge usable: scoped memory, retrieval workflows, verification loops, source-of-truth files, catalog/search-backed chatbots, and agent operating patterns.

AiML SuperAgent is the strongest signal: it treats AI agents as long-running operators that need memory boundaries, context discipline, verification checks, audit trails, and repeatable handoffs.

The surrounding work connects that model to practical knowledge systems: RAG-style product search, chatbot memory, AI-assisted coding workflows, technical writing on verification, finetuning dynamics, RL-style feedback loops, distillation, and full-stack AI products.

I am interested in how frontier models should search, retrieve, rank, remember, verify, and reason over information, including indexing, query understanding, knowledge graphs, and distributed retrieval systems.
