AI Cost Index

AI Cost Index is a public intelligence platform that tracks the pricing of AI models across vendors over time.

Instead of scattered announcements and unclear pricing pages, AI Cost Index provides a structured view of AI pricing facts, historical changes, and vendor comparisons — all backed by verifiable evidence.

It helps developers, startups, and FinOps teams understand who is cheapest, how prices evolve, and what actually changed.

Features and Benefits of AI Cost Index

1. AI Model Pricing Tracker

Track the latest pricing for major AI models across vendors such as OpenAI, Azure, Anthropic, and others.

Prices are normalized into comparable units (e.g., per 1M tokens) so users can instantly see:

• Which vendor is the cheapest

• How pricing differs across providers

• What the current market baseline looks like

2. Pricing Timeline & Change History

Every pricing change is recorded in a timeline.

Instead of guessing when something changed, users can see:

• historical pricing records

• percentage change over time

• when a vendor updated their pricing

This makes AI pricing transparent and auditable.

3. Evidence-Backed Pricing Facts

Every pricing fact is linked to its original evidence source, such as official pricing pages or policy documents.

Users can verify:

• where the pricing data comes from

• when the evidence was captured

• whether the information is still valid

This creates a transparent evidence layer for AI pricing data.
