Fable 5 Outperforms GPT-5.6 Sol on an NP-Hard Optimization Benchmark
A benchmark comparison on an unpublished fiber-network optimization problem found Claude Fable 5 to be the strongest model overall, with more consistent results than GPT-5.6 Sol. The report also suggests the native /goal mode is not a universal performance boost: it sometimes improves results, but often changes the search path in ways that can also hurt outcomes.
