Anthropic Launches Claude Opus 4.8 With Honesty and Uncertainty as Core Features

Anthropic has released Claude Opus 4.8, a new flagship AI model that prioritizes honesty and carefulness over raw performance or speed, according to multiple reports. The model is specifically trained to avoid making unsupported claims and to flag uncertainties about its own work, addressing a common problem where AI systems confidently present incomplete or flawed information.

"The company trains its models to avoid making unsupported claims, and early testers report that Opus 4.8 is more likely to flag uncertainties about its work and less likely to jump to conclusions with thin evidence."
