Task demands correlate with success, but success signatures are model-specific
Simpler tasks correlate with success, but how models succeed varies.
Task demands correlate with success uniformly, with resolved runs concentrating in the low-SNC region for every family and scale, whereas the behavioural signatures of success are family-specific.
Across different AI model families and scales, tasks with lower Spread-Novelty-Centrality (SNC) scores are more likely to be successfully resolved. However, the specific patterns of behavior that lead to success differ between model families, indicating unique strengths or strategies for each.
While both Claude and another model might succeed more often on simpler, less novel coding tasks (low SNC), Claude might achieve this by closely matching the scope of the human-written gold solution, whereas another model might employ a different strategy.
Understand that simpler coding tasks (low SNC) generally lead to higher success rates for AI agents. However, the specific behavioral patterns that define success are unique to each AI model family.
When assuming that a single definition of 'success' applies universally across all AI models.
