How smart is GPT-3.5 Turbo (Jan 2024)?

47 SI-IQ · 90% interval 42–53
Not ranked: too little data

GPT-3.5 Turbo (Jan 2024) is a model from OpenAI, released on Jan 25, 2024. Its SI-IQ is 47 (90% interval 42–53), estimated from 5 benchmark results by 1 independent evaluators.

This model has fewer than 5 independent benchmark results or fewer than 2 different evaluators, so it is shown 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.
