Large Language Models Can Follow Instructions, But Not Many at Once: Phase Transitions in Compositional Constraint Satisfaction
TL;DR
Large language models (LLMs) can effectively follow individual instructions but struggle when faced with multiple simultaneous constraints. Performance significantly declines beyond 5-6 constraints, revealing a critical limit in their compositional capabilities.
✦ Why It Matters
Evaluate the number of constraints in your LLM applications to ensure effective performance.
Key Takeaways
- Limit simultaneous constraints to 5-6 for optimal LLM performance.
- Use Constraint Saturation Evaluation to benchmark model capabilities.
- Recognize that structural constraints are more challenging than lexical ones.
- Monitor individual constraint satisfaction rates to predict overall performance.
How It Works
The study introduces Constraint Saturation Evaluation (CSE), a benchmark that varies the number of simultaneous constraints (k) to assess LLM performance. Each constraint is evaluated by a deterministic verifier, allowing for a clear understanding of how models handle multiple requirements.
