AI leaderboard
Which model leads, overall and by category. These are the public benchmarks the charts you see on YouTube and X are built from. We publish no scores of our own: every number belongs to the benchmark that produced it, captured on a date and credited back to the source.
Real people are shown the same prompt answered by two anonymous models side by side and vote for the better answer. Millions of these blind head-to-head votes are fed into a Bradley-Terry statistical model (the successor to the Elo system it started with) which converts win/loss pairs into a single rating per model. A higher rating means people picked that model more often against strong opposition. This snapshot uses the 'style control' variant, which is the site's default: it statistically adjusts for answer length and formatting so a model cannot climb simply by writing longer, prettier replies.
Limitations: It measures which answer people LIKE, not which answer is CORRECT - a confident, well-written wrong answer can still win a vote. Voters are self-selected volunteers rather than a representative sample, prompts skew toward what that crowd chooses to type, and models with few votes have wide confidence intervals (ci_low/ci_high) that often overlap the models ranked above and below them. Treat small rank gaps as ties.

Bars are scaled across the visible range so small differences stay readable. They do not start at zero. Where confidence intervals overlap, the models are statistically tied: read the top group as a group, not a strict order.

LiveBench
A fixed set of test questions with objectively verifiable answers is run against each model and scored automatically against ground truth - no human voting and no AI judge, so the score is repeatable. This release spans 23 tasks grouped into 7 categories. Each category score is the average of its tasks, and the headline 'global average' is the average of the 7 category scores, so every category counts equally regardless of how many tasks it contains. Scores are percentages: 100 is perfect.
Watch out for: Contamination-LIMITED, not contamination-proof: questions are refreshed from recent sources to reduce the chance a model simply memorised them during training, but that cannot be guaranteed. Scores reflect only these 23 tasks - they say nothing about tone, safety, speed or cost. Many entries are effort/thinking variants of the same underlying model (model_id shows the exact configuration tested), and a variant given more reasoning budget will usually outscore the cheaper default that most people actually use.

Two different units, never one chart
A human-preference rating and a percent-correct score cannot share an axis, so this page never mixes them in one table. A model can top one and not the other, and that is a real signal about what it is good at rather than a contradiction: one asks “which answer did people prefer?”, the other asks “which answer was right?”.
What this page will not do
It will not tell you which AI to use. The benchmark leader is often not the right tool for your work, price, availability, integrations, context length and how well it follows YOUR instructions usually matter more than a point or two of score. Which AI should I use? →
