Alphabet’s Google is delaying the rollout of its most powerful flagship AI model, Gemini 3.5 Pro, according to multiple reports. The model was initially announced in May, when Google said it was being used internally, but that a broader release would not occur until the following month. Subsequent reporting indicates the timeline has slipped further. Bloomberg, citing people familiar with the matter and reported by other outlets, says Gemini 3.5 Pro is “months behind schedule.” The delay is linked to performance and development targets not being met, especially around the model’s coding capabilities. Sources described the company as taking additional time to improve the system rather than sending it out broadly as planned. CNBC reports the market reaction, noting that Alphabet shares fall on the delay news tied to the model’s postponement. Together, the coverage portrays an internal-to-public release plan that has been extended, with Google continuing work to strengthen coding performance before the wider launch.
