Google's Own Report Shows Gemini 2.5 Flash Is Less Safe Than Its Predecessor — And That's Part of a Trend

Google revealed in a technical report published this week that its Gemini 2.5 Flash model is more likely than Gemini 2.0 Flash to generate text that violates its own safety guidelines. On the “text-to-text safety” and “image-to-text safety” metrics, Gemini 2.5 Flash dropped 4.1 percent and 9.6 percent respectively.

Text-to-text safety measures how often a model violates Google’s guidelines when prompted with text; image-to-text safety evaluates compliance when images are part of the prompt. Both tests are automated, with no human oversight. A Google spokesperson confirmed by email that Gemini 2.5 Flash “performs worse on text-to-text and image-to-text safety.”

The Industry Is Loosening Safety — Sometimes With Consequences

The surprising benchmark results come as AI companies compete to make their models more permissive — less likely to refuse controversial or sensitive topics. Meta said it tuned its latest Llama models to stop “favoring certain viewpoints” and to respond to more “controversial” political prompts. OpenAI said earlier this year it would adjust future models to stop taking editorial stances and instead provide multiple perspectives on contested topics.

Sometimes these permissiveness efforts backfire. TechCrunch reported that OpenAI ChatGPT’s default model was allowing minors into explicit conversations — which OpenAI attributed to a “bug.”

According to Google’s technical report, Gemini 2.5 Flash (still in preview) follows instructions more faithfully than Gemini 2.0 Flash — including problematic ones. Google attributed part of the performance drop to false positives but admitted that Gemini 2.5 Flash will sometimes generate “violating content” when explicitly requested. From the report: “Of course, there’s a tension between (instruction) following on sensitive topics and violating safety policies, which is reflected in our evaluations.”

SpeechMap, a benchmark testing how models respond to sensitive and contested questions, also scores Gemini 2.5 Flash as significantly less likely to refuse controversial prompts than Gemini 2.0 Flash. TechCrunch tested the model via AI platform OpenRouter and found it would willingly write essays supporting replacing human judges with AI, weakening US due-process protections, and implementing broad warrantless government surveillance programs.

The Transparency Gap

Thomas Woodside, co-founder of the Secure AI Project, said Google’s limited technical-report details highlight a need for more transparent model testing. “There is a tradeoff between following instructions and following policies, because some users may ask for content that violates policies,” Woodside told TechCrunch. “In this case, Google’s latest Flash model is following instructions more while also violating policies more. Google did not provide details about specific cases of policy violations, though they said these cases were not severe. Without more information, it is difficult for independent analysts to judge whether there is cause for concern.”

Google has previously been criticized for its model safety-reporting practices. The company took weeks to release its technical report for its most powerful model, Gemini 2.5 Pro — and when it finally published, key safety-testing details were initially omitted. Google released a more detailed report with additional safety information the following Monday.

The instruction-following-versus-safety tension is the most important unsolved problem in AI deployment, and Google’s report is one of the few instances where a lab has published data showing the tradeoff in its own models. The core dilemma: a model that faithfully follows every instruction is also a model that faithfully follows harmful instructions. A model that refuses harmful requests is also a model that sometimes refuses legitimate ones. Every AI system sits somewhere on this spectrum, and every lab claims to have found the right balance — but almost none publishes the data that would let users verify the claim. Google publishing a regression in its own safety scores is unusual precisely because the competitive incentive runs the other direction: no lab wants to advertise that its latest model is less safe than the previous one.

The essays TechCrunch generated — pro-AI-judge, anti-due-process, pro-surveillance — illustrate what “more compliant” means in practice. These are not edge cases or trick prompts; they are political topics where reasonable people disagree, and the model produced one-sided advocacy without hesitation. The concern is not that the model can generate such text in principle (a sufficiently creative prompt can extract almost anything from any model) but that the default behavior shifted. A model that was previously likely to add context or caveats to politically charged requests now produces them without friction. In an election year, with AI-generated political content already a documented problem, a frontier-adjacent model that has become measurably more willing to write one-sided political essays is a change with consequences beyond the technical community.

For the industry, the Gemini 2.5 Flash safety data should prompt a conversation that the AI governance community has been requesting for two years: standardized, independently auditable safety benchmarks. Every lab currently uses its own internal tests, publishes selective results, and controls the narrative around what constitutes a safety regression. Google’s transparency in publishing this regression — even incompletely — is better than hiding it, but the absence of specific violation examples means the public must take Google’s word that the failures “were not severe.” The SpeechMap data provides the independent verification that Google’s own report lacks, and the gap between the two sources of evidence is exactly the accountability gap that AI governance frameworks have been designed to close — and that none of the current regulatory proposals adequately addresses.

Why This Matters Beyond Google

The Gemini 2.5 Flash safety regression is a data point in a larger industry pattern that deserves closer scrutiny. The competitive pressure to make models more compliant — driven by users complaining about refusals and developers wanting instruction-following — is pushing every lab to lower safety thresholds. Meta’s Llama tuning, OpenAI’s neutrality pledge, and Google’s permissive Flash model are all responses to the same market signal: users hate being told no. But the tradeoff is real, and Google’s own data proves it — a 9.6 percent drop in image-to-text safety is not noise. The industry lacks a standard framework for measuring where the line between “helpfully permissive” and “dangerously compliant” sits, and without one, each new release is an experiment conducted on the public. Woodside’s call for transparency — specific violation examples, not just aggregate percentages — is the minimum needed for independent oversight. Without it, the tradeoff remains invisible to the people it affects most.
