Lantern Works GPU Rental Price History

A daily history of per-GPU-hour rental prices from tracked cloud GPU providers (H100, H200, A100, L40S, RTX 4090/5090, RTX A6000, B200 and others). This covers tracked providers only, not the whole market.

Snapshot range: 2026-10-27 to 2026-10-29 (3 daily snapshots). The files hold 114 price series, 133 change points and 14 price changes.

Query the live data with an MCP agent

Lantern Works runs a free, read-only MCP server (no API key) over the same live feed this dataset is built from.

Hosted endpoint (nothing to install, 13 tools):

claude mcp add --transport http lantern-works-deals "https://lantern-works-mcp.lantern-works.workers.dev/mcp?ref=hf"

For Claude Desktop, Cursor or VS Code, add https://lantern-works-mcp.lantern-works.workers.dev/mcp?ref=hf as an HTTP MCP server. The hosted endpoint adds four opt-in price-watch tools (create_watch_key, watch_price, list_watches, delete_watch) to the 9 package tools.

Stdio (local, 9 tools):

claude mcp add lantern-works-deals -- uvx lantern-works-deals-mcp

or in an MCP client config:

{"mcpServers": {"lantern-works-deals": {"command": "uvx", "args": ["lantern-works-deals-mcp"]}}}

Main GPU tools: compare_gpu_prices, get_price_changes, estimate_job_cost, rebuild_quote.

Example prompt:

Find the cheapest tracked H100 rental, estimate a 100-hour run on it, and tell me whether that rate changed since yesterday. Show the vendor source and check time for each price.

Files

• gpu_price_points.csv: one row per change point. Each row is the first snapshot date at that price or status for a series (vendor | gpu | tier | vram_gb | gpu_count). Columns: key, vendor, gpu, tier, vram_gb, gpu_count, billing_unit, first_seen, date, hourly_usd, price_usd, status, verified_at.
  • status: ranked; held (published but not ranked, either stale or too thin a marketplace); or removed (no longer tracked).
• gpu_price_changes.csv: day-over-day price changes (from_hourly_usd, to_hourly_usd, change_pct, source_url).
• history.json: the raw upstream file.

Live feeds (always current)

• Current prices: https://thelanternworks.com/api/v1/gpu-prices.json?ref=hf
• Changes since yesterday: https://thelanternworks.com/api/v1/gpu-price-changes.json?ref=hf
• Upstream history: https://thelanternworks.com/api/v1/gpu-prices/history.json?ref=hf

In a notebook:

import json, urllib.request
feed = json.load(urllib.request.urlopen("https://thelanternworks.com/api/v1/gpu-prices.json?ref=hf"))
h100 = sorted((r for r in feed["rates"] if r["canonical_model"] == "H100"), key=lambda r: r["hourly_equiv_usd"])

Sources and method

• Each rate comes from the vendor's own pricing page or API (source_url). A daily job re-reads every source (robots.txt respected) and updates a price only where it parsed one. A rate not re-verified for 7 days is held and not ranked.
• Prices are list prices before tax, storage and egress. Check the vendor page before you pay.

Update cadence

Upstream refreshes daily at about 10:23 UTC. This dataset copy is a snapshot and can lag the live feed until it is re-published.
