Google Cloud TPU pricing

Cloud TPU pricing, PER CHIP-HOUR in USD - explicitly stated on the page. v5e = $1.20/chip-h on-demand (us-central1, us-east5, us-west1, us-west4); $1.416 in us-south1 (Dallas); $1.32132 europe-west1; $1.56 europe-west4 and asia-southeast1. v5p = $4.20/chip-h (us-east5, us-east1). v4 pod = $3.22/chip-h (us-central2). Trillium (v6e) = $2.70 in us-east1/us-east5, $2.97 europe-west4, $3.24 asia-northeast1. Ironwood = $12.00 us-central1. DWS Flex-start halves the v5e/v5p on-demand rate ($0.60 and $2.10) and 3-year commitment takes v5e to $0.54. Page states the console displays this in VM-hours, e.g. a v4 host with 4 chips shows as $12.88/h - 4 x $3.22 - so chip-hour is the correct unit and VM-hour is a display artifact.
