Greptile SummaryThis PR adds a new blog post covering the June 12, 2026 suspension of Claude Fable 5 and Mythos 5 access due to a US government export control directive, along with the corresponding cover image and cache entry.
Confidence Score: 5/5Safe to merge — the change is a self-contained blog post with no logic or infrastructure impact. All changes are content-only: a new markdoc post, its cover image, a cache hash entry, and a trivial lockfile metadata field. The only editorial flag is a model version name in the CTA that may be worth double-checking before publishing. The Claude Opus version name in the CTA of +page.markdoc is worth verifying against the actual released model list before the post goes live. Important Files Changed

| Anthropic was also candid about the limits. It stated plainly at launch that perfect jailbreak resistance does not currently appear possible for *any* model provider, that every safeguard in the industry is vulnerable to some non-universal jailbreaks, and that universal jailbreaks would likely be found eventually. The 30-day data-retention policy it introduced for Fable 5 was designed specifically to help detect and mitigate such attacks quickly. | ||

| # Why Anthropic disagrees with the Claude Fable 5 suspension |

This section is redundant. Let's run a pass on the article and remove redundant information.
| * **Every other Claude model continues to work normally**. | ||
| * **Developers relying on `claude-fable-5`** should switch to another available Anthropic model until access is restored. | ||
|
|

| The bottom line: Claude Fable 5 and Mythos 5 are paused for now. Anthropic says it believes the situation is a misunderstanding and is working to restore access as soon as possible. Until then, Opus 4.8 covers most of the same ground. |

This line feels AI-ish, I'd just remove that
