How smart is GPT-4 (Jun 2023)?

57 SI-IQ · 90% interval 51–63
Not ranked: too little data

GPT-4 (Jun 2023) is a model from OpenAI, released on Jun 13, 2023. Its SI-IQ is 57 (90% interval 51–63), estimated from 4 benchmark results by 1 evaluator.

Data as of Oct 18, 2026 · method 1.0.0

A model is ranked when its results come from at least 5 benchmarks (the two GPQA Diamond runs count as one) in at least 3 areas, from at least 2 different evaluators, and its versions are released no more than 60 days apart. This model does not meet that yet, so it is shown with a provisional estimate but not ranked.

Ability by area (SI-IQ, 90% interval)

Every benchmark result we used

Each score is one value exactly as the source published it: for Epoch AI the best of its run settings, for OpenRouter the median hosting provider (the developer's own hosting when it ran the test). “Implied SI-IQ” is the ability that this single result points to; the overall SI-IQ is their precision-weighted average.

Human preference (Arena)

On the Arena leaderboard, where people vote between two anonymous answers, GPT-4 (Jun 2023) has a rating of 1,276 (1,272–1,280) from 88,723 votes (published Oct 15, 2026). Human preference is a different measure from benchmark ability and is not part of SI-IQ. Arena (Hugging Face)
