Questions people ask
Which is better, Llama 3.1 Instruct 405B or Llama 3.3 70B Instruct?
Llama 3.1 Instruct 405B wins four of the six areas where both have results: coding, reasoning, facts and long documents. Llama 3.3 70B Instruct wins following instructions. They are level on agents.
Which is better for coding?
Llama 3.1 Instruct 405B. It wins 2 of the 2 coding tests both models report; Llama 3.3 70B Instruct wins none.
How do you compare the two?
We use the 33 benchmark tests both models have published scores on. The verdict counts the 11 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 22 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.
