AI model releases 2026
Every AI model launch, preview and reported plan from our reporting, newest first, with prices and the sourced story behind each entry. Updated with every edition.
Prices and claims are what each story reports; a company’s own benchmark stays a company claim. The claim check compares each maker’s main claim with an independent test that our story cites. Released models so far: 6 backed, 9 mixed, 12 not checked yet.

How this tracker works
An entry appears when one of our stories covers a model launch, a preview, a reported plan, or a model becoming available on a new platform. A claim is Backed when an outside test supports it, Mixed when it holds only in part or only in some settings, and Disputed when an outside test contradicts it. The date is the one the story gives; when a story gives none, it is the story’s own date. We add entries with each edition and correct them under the story when a fact changes.
