Jamba 1.5 Large wins more areas, narrowly.Llama 3 Instruct 8B is cheaper.
Scores updated · 13 tests both models report · How we compare
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 rests on a single test.
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.
Llama 3 Instruct 8B costs 98% less for the same work.
The biggest differences
The tests each model wins by the widest margin, up to three each. Scores are out of 100.

Which is better for coding?
Jamba 1.5 Large. It wins the one coding test both models report.
Which is cheaper?
Jamba 1.5 Large costs $2.00 per million input tokens and $8.00 per million output tokens; Llama 3 Instruct 8B costs $0.04 and $0.14. That makes Llama 3 Instruct 8B about 98% cheaper for the same work.
How do you compare the two?
We use the 13 benchmark tests both models have published scores on. The verdict counts the 3 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 10 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.
