While the resource is in use, news refreshes every 10–30 minutes, model specifications and Arena hourly, and Epoch every six hours. Benchmark publishers set their own publication schedule. Cached results may remain visible during an upstream outage; we show the last successful fetch above.
Capability evaluations, human preference and price measure different things. We keep them separate and preserve model variants. Missing data is shown as unavailable, never as a zero score or a free price.
