Anthropic plans to deprecate Claude Sonnet 4 on the Bedrock platform in October, cutting off access for new users. Researchers are concerned because Sonnet 4 is considered one of the most aligned models available, and its removal could hinder safety research. Critics argue that AI labs are undermining their own alignment efforts by restricting access to older models.
