(3 × $2.00 + $8.00) ÷ 4 = $3.50/1M — the $/1M figure blends input and output at 3:1 — that is the only way models with two different rates can be ranked on one axis. Your actual rate depends on your own input:output mix — input only $2.00, 3:1 $3.50, 1:1 $5.00, output only $8.00 per 1M.

The board shows this model's cheapest measured offer ($3.50/1M); the smaller figure under it is the mean of the 10 offers listed below ($3.60/1M). Add those up and divide — it matches.
