Prices from the LLM API Pricing Index, synced daily. Release & benchmark data via Epoch AI (CC BY); deprecation dates from provider metadata. When a new model beats one you use, model recommendations surface it automatically at your token mix.

Track the models you actually use — not a list.

StackSpend connects read-only to your AI providers, flags deprecations before they break your calls, and surfaces cheaper equal-quality swaps from this same live dataset.
