Google Gemini 3.5 Pro AI Model Faces Delays

Google's advanced AI model, Gemini 3.5 Pro, is experiencing a delay of several months, according to sources familiar with the matter cited by Bloomberg. The company is reportedly working to improve the model's performance, especially in coding tasks, which has postponed its planned release.

The delay has sparked discontent among engineers and researchers, who worry about Google losing ground to competitors like OpenAI and Anthropic that are continuously releasing more capable models. The complex internal processes at Google, involving multiple stakeholders and integration into vast product ecosystems like Search and YouTube, are also contributing to the slower pace.

Competitors have recently broadened the gap in AI programming capabilities compared to Google's existing products. Despite recent efforts to adjust training data to improve coding assistance, test results have reportedly fallen short of expectations. Google stated that it is testing Gemini 3.5 Pro and other models with partners while also engaging with the U.S. government on AI safety standards and regulation.

Internal divisions and differing opinions on AI development speed and safety are also cited as factors hindering progress. While some push for acceleration, others express more conservative views on AI's role in coding. Some researchers have already departed Google for rival AI labs, citing dissatisfaction with the company's AI race performance.
