What happened: Thinking of ACE? We Can Do It with Fewer Tokens

IBM researchers show ALTK-Evolve achieves comparable or better accuracy than ACE while using 40-86% fewer tokens by selectively delivering learned guidelines instead of injecting all of them.

Why it matters: Thinking of ACE? We Can Do It with Fewer Tokens

Engineers optimizing LLM agents for cost care when building systems that learn from their own task failures to improve reliability without retraining.

Watch out: Thinking of ACE? We Can Do It with Fewer Tokens

Results are on AppWorld benchmark with specific base models; token savings depend heavily on model capability and task difficulty, requiring per-deployment tuning.
