AI Companies
Where each AI company stands, seen through the same six lenses, with every change logged and sourced.
On the Epoch Capabilities Index the best models from Anthropic, OpenAI and Google sit within 2.4 points. Revenue is less even: Anthropic's annualized revenue reached $65B (Jul 2026) and OpenAI's $50B (Sep 2026). Use is led by ChatGPT: 31% of US adults used it in the past week in March 2026, against 21% for Gemini. Each company below is read through the same six lenses, and every change is logged with its source.

Every company, one table
Data sources →One comparable number per lens, where a source measures several companies the same way. The small number is the rank among the companies in this table that the source covers. A dash is a gap in public data, never a zero.

Epoch AI data →From Epoch AI's database of notable AI models, snapshot 19 Oct 2026. Cost and cluster size are Epoch's estimates for single models; a dash means it has none. Ranks are among these ten companies.

- One lens for everyone. Six lenses, same order, same definitions, for every company. No company gets an extra lens for a product it wants to talk about.
- Changes, not news. An entry must move a number or a rank on a lens. Launch events, interviews and hires do not count unless they do.
- Evidence tier on every line. Independent measure, independent estimate or company data. A company's own claims are replaced when an independent score arrives.
- Gaps stay visible. If no source measures a lens for a company, the page says so.
