Tools & models methodology

Products are classified as model developers, application layers, access aggregators or hybrids. Each relationship has a source. A repository publisher account does not prove model training authorship or legal ownership. Downloadable weights do not imply unrestricted commercial use or free hosting.

Prices are dated, reviewed snapshots. Automated monitoring checks reachability and source-content changes; it does not approve a new price automatically. Changes or failures trigger re-verification. Coverage is growing and bounded by sources and collection limits, not an inventory of every model or site.

We do not publish best-tool rankings without documented criteria and testing. These comparisons cover stated features and prices, not independent benchmarks.
