Methodology & Data Sources
HotON.ai is built on transparent, verifiable data. This page explains exactly where our numbers come from, what is measured versus modeled, and how often everything updates.
Model pricing
Prices are real — pulled daily from the OpenRouter public API and normalized to US dollars per 1 million tokens (input and output shown separately). We do not edit or estimate prices.
Model catalog
We track ~120 current, generally-available models from recognized AI labs. For each model line we keep the newest released version, cap how many we show per provider for balance, and exclude preview, roleplay and proxy variants to keep the catalog professional.
Capabilities & context
Input and output modalities (text, image, audio, video, files) and context-window length come directly from each model's published metadata via OpenRouter.
Performance & reliability
Availability is real — the best-serving provider's 24-hour uptime via OpenRouter. Efficiency is a deterministic HotON composite of real price and context, and cost-per-task is derived from real prices. Speed is a modeled estimate (there is no public real-time throughput source covering every model). Each metric is labeled across the site.
AI indexes
Every index is computed from the live model set: blended price means (global, China, US), an inference-cost proxy, an efficiency average and a multimodal-cost index. Values recompute daily and accumulate a genuine rolling time series.
News & sources
News is aggregated from 20+ public RSS feeds of AI labs and reputable outlets. We store an original short summary with attribution and a link back to the source — we never republish full articles. Category and impact are inferred heuristically.
Tools directory
The AI tools directory is hand-curated by HotON.ai editorial. Names, makers, categories, pricing models and official links are public facts verified from official sources; HotON.ai is not affiliated with the listed products.
Update cadence
A daily cron refreshes prices and recomputes indexes (≈03:42) and ingests news (≈03:17). Pages use incremental static regeneration, so the public site reflects fresh data automatically.
HotON.ai provides market intelligence for information only — not financial advice. Performance metrics are modeled estimates; always verify pricing and capabilities with the official provider before making decisions.
