Context windowHow much information the model can work with in one request, measured in tokens — pieces of words or other data. This includes your question, attachments, conversation and reply. Limits can vary by model variant and provider. | 200k | 128k |

HumanEvalFunction synthesis — 164 small Python problems: the AI is given a function's description and has to write the working function. This was the coding benchmark of the GPT-3.5 and GPT-4 era, before the field moved to fixing real bugs in real repositories. Higher is better. | — | 83.7% |
MATHReasoning — accuracy on the original competition mathematics test set | — | 64.3% |
DROPReasoning — three-shot token F1 on questions requiring reasoning over paragraphs | — | 83.2 |
GPQA DiamondScience — Graduate-level science questions in biology, physics, and chemistry — hard enough that subject-matter PhDs score around 65%. Higher is better. | — | 42.5% |
MMLUGeneral knowledge — A 57-subject multiple-choice exam — history, law, medicine, maths — that was the standard measure of how much a model knows from 2020 until roughly 2024, when frontier scores crowded into the high 80s and labs moved on to harder tests. The scores here were published years apart under different testing setups, so read them as a historical record rather than a like-for-like ranking. Higher is better. | — | 84.7% |
MGSMMultilingual math — solving grade-school word problems translated into multiple languages | — | 87.1% |

codex-mini-latest and GPT-4 Turbo don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. GPT-4 Turbo shipped 557 days before codex-mini-latest, so benchmark comparisons should account for the intervening progress.
Context windows are 200k (codex-mini-latest) vs 128k (GPT-4 Turbo).
Direct benchmark comparisons are unavailable — codex-mini-latest and GPT-4 Turbo don't publish scores on any of the same benchmarks.
