Debugging across the whole stack with Claude Fable 5.1

Claude Fable 5.1 is particularly strong on long-running engineering work, and it's smart enough to fix the root cause of an issue rather than the symptoms.



In this example, Fable 5.1 works through months of vehicle data, support tickets, and several codebases at once to track down a bug the team couldn't reproduce internally. It proposes a cause, and the developer confirms it, decides what's safe to ship, and approves the fix.
