Claude Fable 5 is available in Aisle again. It is still switched off until an admin decides otherwise, and the reason has not changed.
What happened to Fable 5
Anthropic suspended Claude Fable 5 days after launch, under US government export control directives. The Commerce Department has since lifted those restrictions, and following an internal review, Anthropic has fully redeployed the model. It is available again on subscription plans and API usage credits, and it is available in Aisle today.
The model performs the way it did at launch, with one difference worth knowing. Fable 5 now declines certain requests and routes them to Opus 4.8 instead. You get an answer either way, but the model that answered may not be the one you selected.
Why it stays off
Nothing about the retention terms changed while the model was gone, so nothing about our position has changed either. We shipped Fable 5 switched off in June, and it stays switched off.
Anthropic classifies Claude Fable 5 as a "Covered Model" subject to a minimum 30-day data retention policy. Zero Data Retention is not available for this model. Data is automatically deleted after 30 days. The details are in the Anthropic Privacy Policy.
That is a departure from the terms most of our customers rely on, so we do not route any of your data to Fable 5 until someone in your organization decides the trade-off is acceptable. Enabling it is a deliberate, admin-level choice. Your Aisle Organization admin controls it in your organization's model settings. If your organization turned it on in June, open those settings and confirm where you stand today.
The original write-up covers the full reasoning. It still holds.
From the blog
Assistants and Systems. An assistant makes one person faster in a session, and the value belongs to them. A system runs a process whether anyone is at their desk or not, and the value belongs to the company. Mitchell argues every company should run both, deliberately, and that the two get funded by different people for different reasons. Fund only assistants and every process stays somebody's personal responsibility, so it leaves when they do.
