Positives
- Mandatory safety testing for all capable models could ensure a higher standard of safety, which many believe is a reasonable measure.

Concerns
- Anthropic's push for mandatory safety testing feels like a thinly veiled attempt to restrict open models and stifle competition.

- There's a clear impression that Anthropic is more concerned about protecting their profits than genuinely promoting safe AI practices.
