PHYSIX OBSERVATION

While Anthropic plays up the safety risks of open-weight models, it is simultaneously pushing its own high-priced closed-source models, so its stance inevitably carries commercial motives. Open-model supporters value cost and autonomy; if safety rhetoric lacks verifiable standards, it easily becomes competitive messaging. What truly deserves attention is that the industry needs a unified evaluation mechanism, not everyone talking past one another.
