Our position on open-weights models
Anthropic has been the most vocal frontier lab about safety risk, so a formal position on open weights is a real policy marker, not routine PR. This lands the same week Kimi K3 ships and open weights momentum builds in China, so expect Anthropic's stance to shape how regulators and competitors frame the closed versus open debate. Read this closely if you're making build decisions around open versus closed models, or if you're in policy and want to know where the safety-focused lab is drawing lines.
