Anthropic has launched its latest flagship model, Claude Opus 4.5, escalating the fierce competition in the artificial intelligence sector. This release marks a pivotal moment, transforming what was once a technology race into a high-stakes proxy war between tech giants.
Unlike typical product launches, this move involves a rare tactical alliance. Cloud computing rivals Amazon and Google are both backing Anthropic's new model, using Opus 4.5 as a shared weapon to challenge Microsoft's increasing dominance over the corporate AI landscape, a position it cemented through its close partnership with OpenAI.
