Which is better, Claude 3.5 Haiku or INTELLECT-3?
INTELLECT-3 wins four of the six areas where both have results: coding, agents, reasoning and long documents. Claude 3.5 Haiku wins following instructions. They are level on facts.
Which is better for coding?
INTELLECT-3. It wins 2 of the 2 coding tests both models report; Claude 3.5 Haiku wins none.
How do you compare the two?
We use the 15 benchmark tests both models have published scores on. The verdict counts the 10 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 5 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.
