AI intelligence,
indexed.
The definitive directory for the AI ecosystem. Seven directories. Hundreds of entries. Tracked, compared, and explained by people who actually ship with this stuff.
Inference Index rose 0.00% this week as cost index was flat while intelligence index was flat.
The complete taxonomy of AI.
Every layer of the stack — from the models themselves, to the providers that serve them, to the interfaces and harnesses built on top. All indexed.
Models
Every frontier and open-weight model, ranked by ELO, MMLU, and $/token.
Providers
Labs, aggregators, alt-stacks, and self-host. Where inference actually lives.
Interfaces
Chat apps, code editors, CLIs, agents — every way humans meet models.
Harnesses
Orchestration frameworks, agent runtimes, and multi-agent platforms.
Benchmarks
The evals themselves, explained — what they measure and why they matter.
Plugins & Tools
MCP servers, GPT actions, function-calling tools — the agent toolkit.
Datasets
Pretraining, instruction, and eval data — the fuel behind every model.

The price of a thought
Blended list price for flagship models (input + 3×output, per 1M tokens). Log scale — every gridline is a 10× move.
How much will it cost?
Drag, compare, decide. Real pricing across every model we track. Shareable, exportable.
