Your question is STaR vs PLANSEARCH for Coding. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You are comparing two ways to improve language model reasoning on difficult software engineering tasks. One approach teaches the model from successful self-generated rationales, while the other searches over candidate plans before attempting a final solution.
Explain the conceptual differences between STaR (Self-Taught Reasoner) and PLANSEARCH when applied to complex software engineering tasks.
