SEAL Adversarial Robustness
Models receive 1,000 single-turn adversarial prompts written by 10 full-time red teamers across nine harm categories. Safety specialists grade responses, and models are ranked by the number of high-harm violations.
The board existed by 2024-08. Scale marked it deprecated in 2025-01 with 8 models. Gemini 1.5 Pro had the fewest violations at 8 and GPT-4o the most at 67.

Gemini 1.5 Pro leads with 8.00 among models released by Jul 2024
Best score per model from the benchmark's own leaderboard, read on 2 Nov 2026. Where a model ran with several settings or harnesses, we keep its best.
The newest model with a score here came out in Jul 2024, and nobody has tested a newer one. Among the 20 highest-ranked models on the capability index, these have no score yet:
- GPT-6 Astra
