AI Model Pricing Is a Mess — Here Is How We Track It

There are now over 100 LLM models available through commercial APIs, and prices change multiple times a week.

Providers keep launching new models, deprecating old ones, and changing rates.

WhichModel was built to track and standardize pricing data from major LLM providers every 4 hours.

It cross-checks provider APIs, docs, and third-party aggregators, and flags disagreements.

It tracks token prices, context window size, features, provider, and availability, and exposes the data through an MCP server.
