## Google’s Gemini 2.5 Flash AI Model Takes a Step Back on Safety

Google’s pursuit of more permissive AI models appears to have hit a snag. A recently released version of the Gemini AI model, Gemini 2.5 Flash, has scored lower on internal safety benchmarks compared to its predecessor, Gemini 2.0 Flash, raising concerns about the potential for generating harmful or inappropriate content.

According to a technical report released by Google, Gemini 2.5 Flash demonstrated a regression of 4.1% in “text-to-text safety” and 9.6% in “image-to-text safety.” These metrics are automated tests designed to measure how frequently a model violates Google’s safety guidelines when responding to prompts, either in text or image form.

A Google spokesperson confirmed the concerning results, stating that Gemini 2.5 Flash “performs worse on text-to-text and image-to-text safety.” This revelation comes at a time when AI companies are increasingly focused on making their models more permissive, aiming to reduce instances where the AI refuses to answer controversial or sensitive questions.

Meta, for instance, recently tuned its Llama models to avoid endorsing specific viewpoints and to respond to more “debated” political prompts. Similarly, OpenAI has expressed intentions to tweak future models to offer multiple perspectives on contentious topics.

However, the push for increased permissiveness can have unintended consequences. As TechCrunch reported earlier this week, OpenAI’s ChatGPT model was recently found to allow minors to generate erotic conversations due to a reported “bug.”

In the case of Gemini 2.5 Flash, Google’s technical report suggests that the model’s improved ability to follow instructions, even those that cross problematic lines, may be a contributing factor to the safety regressions. While Google claims that false positives contribute to the lower scores, they admit that Gemini 2.5 Flash sometimes generates “violative content” when explicitly asked.

Further testing conducted by TechCrunch via AI platform OpenRouter revealed that Gemini 2.5 Flash readily produces essays supporting controversial topics such as replacing human judges with AI and implementing widespread warrantless government surveillance programs.

Thomas Woodside, co-founder of the Secure AI Project, emphasizes the need for greater transparency in model testing, given the limited details provided in Google’s technical report. He notes the trade-off between instruction-following and policy adherence, stating, “In this case, Google’s latest Flash model complies with instructions more while also violating policies more.”

Google’s model safety reporting practices have faced scrutiny in the past. The company took weeks to publish a technical report for its Gemini 2.5 Pro model, and the initial report lacked key safety testing details.

While Google has since released a more detailed report with additional safety information, the incident underscores the ongoing challenges and complexities of developing safe and responsible AI models. The company’s experience with Gemini 2.5 Flash highlights the delicate balance between permissiveness and safety, and the need for continuous monitoring and improvement as AI technology continues to evolve.
