Vast.ai Observatory
Vast.ai is the only deep-book live GPU marketplace in the panel — hundreds to thousands of distinct offers per chip, refreshed in real time. This page surfaces what the median alone hides: distribution shape, quality bands, $/perf frontier, supply structure, geography, hidden costs, network quality, long-tail catalog, and the time-series of the spread itself. Observatory data — not part of the CCIR rate methodology. Vast is the reference marketplace, not a tier.
Per-GPU $/hr histogram
—
Every live offer on Vast for the selected chip, binned by per-whole-GPU
$/hr (log scale on x). The vertical amber line marks the median; the
dashed grey marks the median interruptible-bid floor. Where the
histogram has a long upper tail, that's the trust premium — buyers
pay 5-50× the floor for verified datacenter offers vs deverified
hosts. per_gpu_dph = dph_total / num_gpus / gpu_frac.
Verified vs deverified bands
—
Median per-GPU $/hr for offers tagged verified (audited
datacenter hosts) vs deverified (hosted, unverified).
The premium varies sharply by chip — RTX 4090 verified is ~2× deverified
but H100 SXM verified can be cheaper than deverified.

Multi-GPU offer structure
—Count of live offers by GPU count (1×, 2×, 4×, 8×, other) for the selected chip. Reveals whether the chip has scale-up supply or only single-GPU rentals — material for buyers planning multi-node training.

Egress + storage costs
Per-offer distributionEgress cost ($/TB) and storage cost ($/GB-mo) distributions across live offers. Egress ranges $0–$50/TB on Vast — most marketplaces never surface this number per offer.
Internet-down distribution
—Bandwidth distribution is bimodal: consumer-hosted GPUs at gigabit-class, proper datacenter offers at multi-Gbps. Same chip, very different connectivity — matters for training jobs that pull from cloud storage.

Distribution evolution over 30 days
—Five lines show how the per-GPU $/hr distribution shifts over time: p10 (cheapest 10%), p25, p50 (median), p75, p90 (most expensive 10%). When spread widens, supply is fragmenting; when it narrows, the market is converging. This is the unique CCIR view — no other public source publishes the spread of a marketplace over time.
Refreshed every three hours alongside /marketplace. Vast bundles API authenticated via CCIR research key — values are public list-asks as Vast publishes them. Distribution shape captured at the cycle Vast served the query; offers churn faster than this cadence so the histogram is a snapshot, not a long-window aggregate.
