Research directions
Scientific media
Code-generated animation and narration for explanations that need more structure than pixel generation provides.
Agent memory
Hybrid retrieval, knowledge graphs, temporal updates, and benchmarks for context that persists.
Accessible computing
Programming languages and learning environments built around local language and context.
