Small Agents with Semantic Search: Efficient Multilingual Code Localization

Locating relevant files from natural-language requests is a core subtask for agents operating over code repositories. We investigate whether this task can be delegated to compact, specialized models to enable on-device search while reducing the token usage, latency, and inference cost of larger agents. We show that sem...

DenseOn with the LateOn: Fully Open Dense and Late-Interaction Models for Multilingual, Long-Context, and Code Search

An open end-to-end recipe for training retrieval models and study how English supervision transfers to multilingual retrieval through translate-train are presented, suggesting that token-level matching turns translate-train from a target-language expansion strategy into a multilingual generalization recipe.
