Comprehensive Benchmark Data Fetcher
=====================================
Strategy:
1. Fetch per-question results from TOP models on each benchmark
2. Collect ~1000 questions total across GPQA, MMLU-Pro, MATH
3. Compute success rates from strongest models only
4. Post-process to stratify by difficulty:
- LOW success (0-30%): Hard boundary - model limitations
- MEDIUM success (30-70%): Capability boundary - interesting edge cases
- HIGH success (70-100%): Within capability - baseline
This gives us the full spectrum to understand LLM capability boundaries.
