Anthropic has released Opus 5, a new version of its flagship large language model, which offers performance close to its top-tier Fable 5 model but at half the price. The company states that Opus 5 excels in knowledge work, complex coding, and scientific research, showing improved capabilities over its predecessor, Opus 4.8. Anthropic has also enhanced Opus 5's safeguards, aiming for reduced intervention rates compared to Fable 5 and lower rates of deceptive behavior, while specifically avoiding training on cyber-related exploitation tasks.
