AI Resource Library
Build with AI, spend less.
A shelf of resources I point builders to: live tools that compare model capability, API prices and inference providers, so you can pick the cheapest route that still does the job. Prices in this space change weekly, which is exactly why live tools beat static price lists.

Compare models & prices
Start here when choosing a model or an API provider. Each tool covers a different angle: capability, live price, or provider spread.
Artificial Analysis
Independent benchmarks for the major models: intelligence, cost per real task, output speed and latency, tracked continuously. The fastest way to see which model is actually worth its price.
Provider comparisonArtificial Analysis · Providers
The same model, served by different providers, compared on price, speed and latency. The same weights can cost several times more depending on where you call them.
Live pricesOpenRouter · Models
Live API prices, context windows and free variants for hundreds of models, all reachable through one API key. Check the price of a model here before you commit to it anywhere else.
Provider directoryInfrabase · Inference APIs Compared
149 inference providers side by side: per-token prices, free tiers and deployment options. Built for finding the same model on a cheaper endpoint, or a free tier to prototype on.
