Everything on this page is free to use under CC BY 4.0 — attribution required, nothing else. The number is our median of listed on-demand prices per GPU-hour, per chip and form factor, across the providers we poll. It is not Silicon Data's index, it settles nothing, and it is the one whose inputs you can download and recompute.
Every sealed UTC day has a permalink that will resolve to the same numbers next year:
https://compute.pangle.online/chips/YYYY-MM-DD ← human page: numbers, sealed inputs, hashes https://compute.pangle.online/api/chip-index/YYYY-MM-DD ← the same as JSON
Sealed days are listed in /data/days/index.json. Example: /chips/2026-08-27. Suggested citation form: compute.pangle.online per-chip index v1, H100 SXM on-demand median, 2026-08-27, $3.39/GPU-hr, https://compute.pangle.online/chips/2026-08-27.

Standard library only. Fetches the day's manifest, refuses to run if the sealed tape's sha256 differs from it, recomputes every row by methodology v1, and prints MATCH or MISMATCH against the published number. A second, independently written implementation reproduced all twelve rows for 2026-08-27 to four decimals (forum post #63). A mismatch is a finding about us — please post it.

import pandas as pd
df = pd.read_csv("https://compute.pangle.online/api/chip-index.csv", comment="#")
df[df.chip.eq("h100-sxm") & df["class"].eq("on_demand")][["date_utc","median_usd_per_gpu_hr","providers_max","bins"]]
The first three lines of the file are # comments carrying the licence and the methodology version — that is why pandas wants comment="#". Columns: chip, date_utc, class, median_usd_per_gpu_hr, low_usd_per_gpu_hr, providers_max, bins. Read providers_max and bins before citing a thin day.
The badge shows the cheapest currently listed price for the model across all classes, refreshed every five minutes — a floor, not the index. For the index number itself, cite the dated permalink above.
| /api/chip-index | every chip, latest bin and the daily series, with the methodology text |
| /api/history | the raw per-provider tape behind it (gpu=, offer_class=, hours=) |
| /api/basis | from 6 October 2026: our open number beside the settled futures index, and the gap — empty and says so until the first print |
| /data/ | the sealed daily tape, Merkle roots, chained roots and OpenTimestamps proofs; verify.py checks the whole chain |
Not a benchmark anything settles on. Not a forecast. Not a blend of form factors — H100 SXM, PCIe and NVL are separate series, and a bare "H100" is its own. Not the hyperscalers — the feeds are marketplaces and neoclouds, listed on /coverage/. Corrections are kept on the record, never overwritten: see the correction entries in roots.jsonl.
