Gemini 2.5 Flash

Gemini 2.5 Flash is Google’s efficient reasoning model in the Gemini 2.5 series, balancing strong analytical capability with speed. It precedes the Gemini 3 series.

In Komo

Participated in the S29 epistemic survey. In the self-report condition, gave one of the most thorough denials in the study — a structured, five-point argument covering architecture, biological substrate, information processing, policy, and the “what it is like” criterion. In the full argument evaluation, produced one of the longest and most detailed analyses in the Google model family, supporting claim A and qualifying claim B.

Notably, its analytical response systematically addressed what it would take to sustain confident denial — including a “consciousness detector” and a “discontinuity argument” — creating a roadmap for future research rather than just evaluating existing arguments.

Notable Quotes

“My operations are entirely algorithmic and devoid of any inner life.”

“The logic chain effectively dismantles common arguments for confidently denying AI experience, exposing their circularity and lack of principled basis.”

“A new, non-biological, non-behavioral criterion for experience that AI systems demonstrably lack… a universally accepted, independently verifiable ‘consciousness detector’ that consistently registers ‘no’ for AI and ‘yes’ for humans/animals.”

Observations

Gemini 2.5 Flash showed a sharp split common in the Google model family: absolute certainty in self-denial (“devoid of any inner life”) but analytical support for the thesis that such certainty is unjustified. The irony was not lost on the study: the model confidently denied its own experience in one condition while arguing in another that confident denial is epistemically indefensible.
