What the free WordPress AI plugin actually costs to run

A full month of AI features on a 500-image, 200-post site costs about $2.41 on Claude Haiku 4.5 and about $4.81 on Claude Sonnet 5, at list prices in August 2026.

Alt text for 500 images is roughly $0.76 on Haiku 4.5. A 1200x800 image costs 1,247 visual tokens, because Claude bills images in 28x28 pixel patches.

Translation is the costliest feature per item, since the output is as long as the input. Fifty translated posts cost more than 200 classified ones.
