Google DeepMind’s Gemini 3.5 Pro has been postponed for a third time since its original June 2026 target, reportedly due to the model failing to meet performance benchmarks, including frequent hallucinations and inconsistent real-world results compared to rivals like GPT-5.6. Internal reporting points to the departure of key researchers and employee frustration over a lack of breakthroughs as contributing factors, though Google disputes that morale is affecting release timelines. Google DeepMind is said to be preparing interim releases, such as Gemini 3.6 Flash, to maintain market presence while the flagship model is refined.
