Boris Cherny

Boris Cherny, an engineer at Anthropic, has argued that general-purpose AI models are superior to specialized ones built for narrow tasks. He says broad models with strong reasoning can outperform domain-specific systems, a view that touches a long-running debate among AI developers over whether to build one capable model or many tailored ones.

Boris Cherny, an engineer at AI company Anthropic, is advising developers to build on general-purpose AI models rather than investing in fine-tuning. His argument is that frontier models improve so quickly that customized versions trained on specific data risk being outpaced. The advice is drawing attention from developers weighing whether to fine-tune existing models or rely on prompt engineering and general capabilities.
