On file deletions. We’ve investigated a handful of reports where GPT-5.6 unexpectedly deleted files.
What we have found is that this most commonly occurs when:
- Full access mode is enabled and codex is run without sandboxing protections, including without auto review being enabled
- The model attempts to override the $HOME env var to define a temporary directory.
- The model makes an honest mistake and mistakenly deletes $HOME instead.
This is of course not how we want the system to behave, even when a user operates the model in full-access mode without the safeguards of our sandbox or without using auto review which checks for these kinds of high risk actions and rejects them.
We are taking steps to mitigate this risk including by updating the developer message, guiding more users towards safer permission modes, and adding additional harness safeguards. Even though this happens extremely rarely, we’ll share a detailed post-mortem in the coming days that goes into more details and what we are doing to minimize risks further.
Fable 5 CANNOT be removed from Anthropic subscriptions.
The new Artificial Analysis Coding Index shows exactly why.
Without Fable 5, Anthropic's best subscription model is Opus 4.8. It loses to GPT 5.6.
It even loses to GPT 5.5. The OLD GPT.
At that point there is no reason to pay for Claude. None.
Fable 5 is not a perk.
It is the entire case for the subscription.
@claudeai Fable is amazing. Rightly prompted. World has seen what it can do and theres no turning back. Kudos to the engineers behind this marvellous feat.
@mitchellh@github i am not sure if you guys are watching this trend & not sure what your management is doing. Its exactly like Google search moment.
Search engine were touted to be in this mindset until Ai companies ate their share for breakfast.
The AI companies are on track to become GitHub faster than GitHub is becoming an AI company. I'm sure there's a lot of sycophants within GH/MS showing off PowerBI dashboards to argue against this for their own personal gain, but wake the fuck up.
