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.

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.

8 toolscompare_pricesCompare Prices Across VendorsARead-onlyIdempotentInspect
Cross-vendor price comparison for a specific model or model family.
Shows the same model (or family) priced across different vendors, sorted cheapest first. Essential for cost optimization and vendor selection.
Examples:
"Compare Llama 3.1 70B pricing across vendors" → model_name="Llama 3.1 70B"
"Cheapest GPT-4 family output pricing" → model_family="GPT-4", direction="Output"
"Claude pricing comparison" → model_family="Claude"
Inputs: model_name, model_family, direction, modality, +2 more.
get_index_benchmarksGet AIPI Index BenchmarksARead-onlyIdempotentInspect
AIPI (ATOM Inference Price Index) — chained matched-model price benchmarks for AI inference.
Returns 14 benchmark indexes across four categories:
Modality (6): Text, Multimodal, Image, Audio, Video, Voice — what does this type of inference cost?
Channel (4): Model Developers, Cloud Marketplaces, Inference Platforms, Neoclouds — where should you buy?
Tier (3): Frontier, Budget, Reasoning — what's the premium for capability?
Special (1): Open-Source — how much cheaper is open-weight inference?
Each index includes input, cached input, and output pricing per period.

Scored across 8 tools
Tools are largely distinct, though compare_prices and get_model_detail both return cross-vendor pricing for specific models, which could cause selection uncertainty. The three market-level analytics tools (get_index_benchmarks, get_kpis, get_market_stats) serve different analytical purposes but operate on similar aggregate data.
All 8 tools follow a consistent verb_noun pattern (compare_prices, get_index_benchmarks, get_kpis, get_market_stats, get_model_detail, get_vendor_catalog, list_vendors, search_models). No mixing of camelCase, snake_case, or inconsistent verb styles.
8 tools is well-suited for the AI inference pricing intelligence domain. The set covers discovery (search_models, list_vendors), detailed lookups (get_model_detail, get_vendor_catalog), price comparison (compare_prices), and market analytics (get_index_benchmarks, get_kpis, get_market_stats) without redundancy or bloat.
Strong coverage for read-only market intelligence including model discovery, vendor exploration, price comparison, and market benchmarks. Minor gaps include no explicit historical pricing trends for individual models over time and no direct side-by-side vendor comparison tool (requiring manual comparison of vendor_catalog outputs).
