Where each one wins

Tests won in each of the two areas where both have results. Each piece is one test, so a longer bar means more evidence; grey means the two scored within a point of each other.

Coding and reasoning rest on a single test each.

What it costs

Prices per million tokens, roughly 750,000 words. The bars show the cost of a million tokens read plus a million written.

Questions people ask

Which is better, Claude 3.5 Sonnet or DeepSeek-R1-Zero?

Claude 3.5 Sonnet and DeepSeek-R1-Zero each win one of the two areas where both have results. Claude 3.5 Sonnet wins coding; DeepSeek-R1-Zero wins reasoning.

Which is better for coding?

Claude 3.5 Sonnet. It wins the one coding test both models report.

How do you compare the two?

We use the 18 benchmark tests both models have published scores on. The verdict counts the 2 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 16 are listed but not counted, because several are summary scores or repeat a test. Each score is the one shown on the model's own page.
