Google Hides Gemini 3.5 Flash Hallucination Data
TL;DR. Google has not disclosed hallucination rates for its Gemini 3.5 Flash AI model, a departure from competitors like Anthropic and OpenAI. - The Gemini 3.5 Flash system card contains no references to hallucinations or sycophancy. - This lack of transparency contrasts with other major AI developers who publicly report similar model metrics. - Google is integrating AI Mode and AI Overviews more deeply into Search, potentially exposing users to inaccurate information.
- Google has not published data on how often Gemini 3.5 Flash hallucinates or acts sycophantic.
- Unlike Google, competitors Anthropic and OpenAI provide public data on their AI models' hallucination rates.
- The absence of this data is notable as Google expands AI features within its core search product.
