从技术层面看,2025年第四季度以来,公司围绕M2系列持续迭代:M2强调效果、价格与速度之间的平衡;M2.1强化复杂任务处理能力;M2-her针对互动类产品场景优化;2026年2月发布的M2.5,则进一步提升编程与办公场景表现,并在推理效率与成本控制上进行压缩。

If we're in a pessimistic scenario… Anthropic's role will be to provide as much evidence as possible that AI safety techniques cannot prevent serious or catastrophic safety risks from advanced AI, and to sound the alarm so that the world's institutions can channel collective effort towards preventing the development of dangerous AIs. If we're in a "near-pessimistic" scenario, this could instead involve channeling our collective efforts towards AI safety research and halting AI progress in the meantime. Indications that we are in a pessimistic or near-pessimistic scenario may be sudden and hard to spot. We should therefore always act under the assumption that we still may be in such a scenario unless we have sufficient evidence that we are not.
