Woofun AI reports that Google has yet to release its next-generation frontier model, Gemini 3.5 Pro, despite recently launching three faster and cheaper AI models. Meta Chief AI Officer Alexandr Wang posted on X regarding Meta's Spark model ranking higher than Google's recent releases, stating "gemini who?" OpenAI researcher Thibault Sottiaux also responded on X to Google employee Logan Kilpatrick's post about Gemini 4 starting pre-training, saying "hope it finishes one day as well."

Raymond James analyst Josh Beck stated that the delay of Gemini 3.5 Pro has shifted external perception from leading to lagging. Moor Insights & Strategy analyst Anshel Sag said it is "a bit strange" for Google to promote Gemini 4 before delivering Gemini 3.5 Pro. Google has not commented on this.
