It replaces older turns and Agent steps with LLM-generated summaries. Long-running Agents keep a condensed record of earlier goals, decisions, and open work. It summarizes as little as needed to reach the target size, starting with the oldest historical turns and only then moving to the current task's older steps. The min_keep_steps newest steps always stay as they are. You can use a small, cheap model to write the summaries. from haystack . components .
