  • All Implemented Interfaces:
    
public abstract class SlidingWindow
extends JsonSerializable

    Context window will be truncated by keeping only suffix of it.

      • targetTokens

         abstract Optional<Long> targetTokens()

        Session reduction target -- how many tokens we should keep. Window shortening operation has some latency costs, so we should avoid running it on every turn. Should be <trigger_tokens. If not set, trigger_tokens/2 is assumed.
