Anthropic releases Claude Fable 5 and Mythos 5 with enhanced coding and science skills
ByPulseAugur Editorial·[19 sources]·
Anthropic has launched two new AI models, Claude Fable 5 and Mythos 5, with significant improvements in coding and scientific research capabilities. Fable 5, the publicly available version, demonstrates advanced performance, such as completing a complex coding task in a single day. However, for sensitive topics like cybersecurity and biology, Fable 5 is designed to fall back to the older Opus 4.8 model to ensure safety, with less than 5% of sessions triggering this fallback.
