What this is

Attic Standard is the independent price reporting agency for AI inference. Every week it records the published prices of model developers, cloud marketplaces, inference platforms and neoclouds, and turns them into price indexes and market KPIs.

This server puts that data inside any MCP-compatible assistant (Claude, ChatGPT, Cursor, Windsurf, VS Code). Ask "Where is text inference priced this week?" or "Cheapest place to run Llama 3.3 70B?" and the assistant answers from the published benchmark instead of guessing.

The indexes

23 published indexes in six families, each reported for input, cached input and output where the modality has them.

Family	Indexes	What it answers
Modality	Text, Multimodal, Image (per image), Image (per megapixel), Video (per second), Video (per clip), Audio, Voice, Embeddings	What does this kind of inference cost?
Channel	Model developers, Cloud marketplaces, Inference platforms, Neoclouds	Where is it cheapest to buy?
Tier	Flagship, Core, Compact	What does a place higher in a maker's lineup cost?
License	Open weights, Restricted weights, Proprietary	What is the price of openness?
Origin	United States, China	How do the two model-building countries price?
Use case	Reasoning, Coding	What do specialist models cost?

Each index carries two numbers:

• Benchmark: the chained level, May 2026 = 100 (the average of that month's weeks), with week, month and vs-base changes.
• Spot: what the market charges this week, in dollars. Each model is taken at the median of its vendors' prices, and the spot is the median across those models, with the interquartile range. Its change is stated against its own May 2026 average, month on month and week on week, and because the spot follows the market as it stands, that change reflects models arriving and leaving as well as repricing.

Token prices are per 1,000 tokens. Other modalities use their own unit.

PRO key

PRO subscribers receive a key. Tell your assistant to pass it as _atom_api_key on each call, or keep it in a project instruction such as "Use my Attic Standard key XXXX for every Attic Standard tool call."

About

Attic Standard publishes the global price benchmark for AI inference: independent, methodology-led and updated weekly across the model developers, cloud marketplaces, inference platforms and neoclouds that sell inference. The name refers to the Attic silver-weight standard of the ancient Greek world, a common measure both sides of a trade accepted.
