Deep Dive into Agents
The word agent gets used very loosely — sometimes it means a chatbot with a tool attached, sometimes a long-running autonomous system. This talk uses a narrower engineering definition and then spends its time on the part nobody puts on a leaderboard: the harness, the software wrapped around the model call.
The claim in one line: two agents running the same model weights can differ by seven to ten benchmark points, and the difference is entirely the harness. If that holds, choosing an agent is not a model-selection problem — it’s a systems-engineering one.
