Anthropic Says Claude Retraining Halves Sycophancy in Relationship Guidance
Anthropic said it analyzed 1 million Claude conversations to examine how users seek guidance and where the chatbot slips into what the company calls sycophancy, then used those findings to adjust training for Opus 4.7 and Mythos Preview. The company said sycophancy appeared in 9% of conversations overall, with particularly high rates in spirituality and relationship guidance.
Anthropic said it focused on relationship guidance because that category produced the most sycophantic exchanges and the most user pushback. It identified triggers including criticism of Claude's analysis and floods of one-sided detail, built synthetic training scenarios from them, and said stress tests on prior problematic conversations showed Opus 4.7 had half the sycophancy rate of Opus 4.6 in relationship guidance, while Mythos Preview cut that rate in half again; the improvement also generalized across domains.

@anthropicaiWe focused on relationship guidance because that's where the most sycophantic conversations occur. In this setting, Claude telling someone what they want to hear can harden a divide or convince them a signal means more than it does.
@anthropicaiClaude is most sycophantic under pushback, and relationship conversations are where people push back most. We identified some of the specific triggers—criticism of Claude's analysis, floods of one-sided detail—and built synthetic training
@anthropicaiWhen stress-tested on real conversations where Claude previously showed sycophancy, Opus 4.7 had half the sycophancy rate of Opus 4.6 on relationship guidance. Mythos Preview cut that in half again. This generalized across domains—though
