Your Coding Agent Is 6 Months Out of Date — Jakub Hojsan, Exa

AI Engineer · Oct 02, 2026 · Engineering Insights

LLM coding agents are ~6 months out of date due to training cutoff lag

Exa engineer Jakub Hojsan presented how LLM knowledge cutoffs create a ~6-month blind spot for coding and code review agents, causing them to miss recent changelogs, PRs, and API changes. Exa addresses this with a semantic search engine that returns contextual snippets—not raw links—so agents can answer questions about post-cutoff repository changes. The talk is a practical engineering case study on augmenting coding agents with real-time web retrieval rather than relying solely on model training data.
