Swallow - Post-trained English - AIME: leaderboard

From the Swallow LLM Leaderboard (Institute of Science Tokyo) post-trained English board, a Swallow-harness rerun that evaluates instruction-tuned and reasoning models. AIME 2024 and 2025 problems (integer answers), zero-shot with a chain-of-thought prompt; metric is accuracy. The scraper pins upstream's aime_2024_2025 field and fails if the problem years change. Upstream publishes 0-1 scores; shown as 0-100, higher is better.

Metric: Accuracy (%). Source: swallow-llm.github.io. Saturation forecast: Estimated already saturated. 68 models tracked.
