Microsoft and enterprise customers are not using Fable 5 yet.

Here is why.

Anthropic holds all your traffic for 30 days. Every prompt. Every output.

The clause is in the usage agreements. You send data to Fable. Anthropic keeps it for a month.

Microsoft integrated Fable into Copilot but restricted internal employee use. That tells you the trust issue is real.

Fable 5 is the best model Anthropic has ever shipped. But the data retention clause just cost them enterprise adoption.
