About Mythos LM

Mythos LM is an independent reference wiki covering Anthropic’s Mythos-class models — Claude Mythos Preview, Claude Fable 5 and Claude Mythos 5 — and the Project Glasswing program that gates access to them. We publish 60 sourced, dated pages: explainers, comparisons, availability mirrors and a glossary.

What we are

• Independent. Published by AXIA Enterprises. We are not affiliated with, endorsed by, or sponsored by Anthropic PBC.
• Original. Every page is written from scratch. We never reproduce another publisher’s text; quotes stay under 15 words and are attributed.
• Sourced. Fact-bearing pages carry a visible Last reviewed date and link to their sources. Numbers Anthropic has not officially published are labelled unofficial.
• Honest about status. Our “is X available?” pages read live data from Anthropic’s public status page and defer to the canonical verdict on our sister site.

How accuracy works

Specs and pricing live in a single sourced dataset; comparison tables are generated from it so a correction propagates everywhere at once. Availability is never hardcoded — it is derived at build time from the public Anthropic status page, and if that source is unreachable we show the last-known-good value with an explicit “as of” timestamp rather than guessing.

The flagship

For breaking news, incident timelines and the always-current verdict, see our sister site anthropicmythos.ai. That site owns the news and status layer; Mythos LM owns the durable reference layer — definitions, comparisons and explainers.
