Price history
Each point is the daily cross-provider median for this SKU and pricing type (per-provider medians first, so no marketplace’s volume dominates). Gaps are gaps — we don’t interpolate missing data.
The spread: the same NVIDIA B300 ranges from $5.95 to $7.50 per hour across tracked providers right now — a 1.3× difference. This is why we exist.

Anatomy: why it costs this
Everything that has to exist before one B300-hour can be rented — then the arithmetic on the parts that can be priced honestly.
NVIDIA hasn’t published a power spec for this part that meets our bar, so no electricity line is computed — a gap beats a guess.
