- Anthropic's Fable model was released but quickly faced export controls, leading to its temporary removal before being restored with stricter safeguards.
- The author attempted to use Fable for a software porting task involving rewriting a C++ tool (salmon) in Rust, but it was rejected due to safety concerns related to biological terminology in the source code.
- Fable also refused to engage with a theoretical computer science problem about network evolution, even after the problem was stripped down to an abstract mathematical form, suggesting the classifier overflags topics like biology and cybersecurity.
- The author concluded that Fable is not useful for research-level tasks in computer science, especially in fields like bioinformatics and computational biology, due to its overly restrictive safety measures.
