Semantic Early-Stopping for Iterative LLM Agent Loops
Researchers propose semantic early-stopping for multi-turn LLM agent loops, replacing fixed iteration caps with embeddings-based convergence detection. The approach halts when consecutive drafts stop shifting in meaning and quality plateaus, reducing token waste on simple tasks while preserving depth on harder ones. This addresses a fundamental inefficiency in agentic workflows where syntactic limits either overspend or truncate prematurely. The work includes formal termination proofs and empirical validation, offering practical gains for production systems running iterative refinement loops like writer-critic architectures.62
