Gemini 3.5 Pro

Model ● Covered in 9 stories + Follow

Gemini 3.5 Pro is a flagship generative AI model from Google that has been repeatedly delayed after being revealed at May I/O. Across recent coverage, Google has shipped or announced multiple lower-cost “Flash” variants (and other new Gemini models) while Gemini 3.5 Pro remains unavailable, with delays attributed to internal performance targets not being met—particularly for coding—and ongoing organizational leadership changes at DeepMind. The model’s absence has been a recurring point of scrutiny as competing flagship releases move ahead.
