Currently, the top score is GPT-5-Medium with 150.
In fact, the benchmark is normalized so that
claude-3-5-sonnet-20240620 has score 130
gpt-5-2025-08-07_medium has score 150
If this doesn't remain the case, this market will resolve N/A.
Otherwise, this market will resolve to the highest ECI for a model released before May 2026.
