# Gemini 3 Pro

**Type:** Tool (LLM) · **Vendor:** Google · **Canonical name:** Gemini

One of the three Large Language Models tested in the authors' experiments (alongside [[entity-chatgpt-5-1]] and [[entity-claude-sonnet-4-5]]). Sampled 150 times each across luxury stimuli ([[claim-ai-ignores-implicit-cues]]) and part of the 5,400 car-brand evaluations ([[claim-luxury-hierarchy-flat]]).

**Signature behavior:** Gemini 3 Pro appeared **indifferent** to the luxury context (a Van Gogh painting) when evaluating willingness to pay for a Ferrari — the neutral pole in [[claim-model-idiosyncrasy]].

**Enrichment / version caveat:** The supplied sources confirm Gemini (Google's model family) was one of the evaluated systems but do not confirm the exact "3 Pro" version label. Treat the version as reported-by-source.
