Tuesday ended late with an announcement from Anthropic.
Claude Mythos 5 and Fable 5 return Wednesday. Globally. The government finally nodded.
Fable 5 had top-tier cybersecurity guards. Anthropic reminded us. It pushed for consistent model evaluation standards too, part of Project Glasswing.
Back in June, Fable 5 dropped.
It lasted a week.
Just seven days. Then an export control order hit. Block foreign nationals, the command said. Anthropic’s math didn’t allow a patchwork fix. To comply meant pulling the plug on everyone. Total blackout.
“Although we have reached a constructive resolution…” the statement read, “these events have made clear that the industry…”
It wants a shared way to assess jailbreaks. To triage findings. To tell partners what the actual risk looks like without guessing games.
Access rolls out slowly. Try the new Sonnet 5 if you can’t wait, also Tuesday’s release.
Anthropic is working on AWS. Microsoft Foundry. Google Cloud. “As quickly as possible.”
Here’s the catch. Pro, Max, and Team plan holders get a reprieve. Up to 50% of your weekly tokens are free for Fable 5 usage through July 7.
After that? Extra charges apply.
Mythos 5? That stays locked behind project gates. Only select US companies in Project Glasswing get near it.
Howard Lutnick posted on X. The Commerce Secretary said they spent two weeks analyzing and approving Fable 5. Aligning the US government. Strengthening America’s AI leadership.
It hasn’t been smooth.
Trump and Anthropic fought all spring. The Pentagon wanted Claude for all legal military work. Anthropic balked. The response: declared a supply chain risk.
Until recently, the admin was hands-off. Now they block frontier models.
June 2’s executive order demands DoD reviews all new models before wide release. Fable and Mythos got stopped under a different legal mechanism but the intent is clear. Government approval first.
Who else wants the keys before we open the door?
We wait for Wednesday.
