Official names, not Claude myth
Use Claude Fable 5 and Claude Mythos 5 in page titles, metadata, and FAQ copy. The phrase Claude myth can be served as search intent, but the copy should correct it rather than treating it as a third model.
Availability must be checked live
There is an official-source tension to preserve: the model overview describes Fable 5 launch availability, but Anthropic's June 12 access statement says access to Fable 5 and Mythos 5 was suspended for all customers while Anthropic works to restore it. For SEO copy, that means overview status is safer than a direct product claim.
What high-quality analysis adds
Simon Willison's hands-on Fable 5 write-up is useful because it focuses on practical integration details: speed, cost, API guardrails, fallback behavior, large-context work, and the kinds of tasks that expose a frontier model's strengths. Treat those as analysis angles; keep specs, IDs, and availability anchored to Anthropic primary sources.
Voloshow workflow boundary
This blog should help users prepare briefs, integration checklists, and terminology corrections. It should not imply Voloshow routes prompts through Claude Fable 5 or Claude Mythos 5 unless Product configuration, provider access, and legal/compliance review later confirm that capability.
