Reliance on prompt engineering
The reliance on prompt engineering to guide question generation introduces a potential bottleneck and a source of bias, as the model's output is constrained by the initial prompt design. This reliance on manual input limits the system's autonomy and could inadvertently steer the model towards specific solutions or introduce biases present in the prompt itself.
Lack of guaranteed question quality
The lack of guaranteed question quality, safety, relevance, and interestingness poses a challenge for scaling the approach. Without external oversight, the model could generate nonsensical, unsafe, or irrelevant questions, hindering its learning process and potentially leading to undesirable outcomes.
Absence of ground-truth rewards
The absence of ground-truth rewards or perfect verifiers limits the model's ability to assess correctness accurately. The reliance on internal heuristics like self-consistency and majority voting introduces a risk of reinforcing systematic errors, especially when the model consistently converges on an incorrect but internally consistent solution.
Only small-scale experiments were performed. It is unclear how well this method would perform when scaled to larger models or more complex tasks.
