Google releases Gemini 3.7 Flash as Gemini app hits one billion users

Google has released Gemini 3.7 Flash, the newest iteration in its Gemini 3 series of multimodal reasoning models. The model is accessible via the Gemini API for developers, with comprehensive feature coverage detailed on the company’s latest model page.

Described as a highly-capable, natively multimodal reasoning model, Gemini 3.7 Flash represents the latest step in Google’s artificial intelligence development. The release documentation notes that the 'minimal' parameter is not supported by the model and will return an error if attempted.

The launch coincides with a significant milestone for the broader Gemini ecosystem. Google CEO Sundar Pichai announced on Tuesday that the Gemini app has surpassed one billion monthly active users, marking it as the company’s fastest-growing product ever.

This user count places Gemini on par with OpenAI’s ChatGPT, which also reached the one billion user mark. OpenAI had previously announced that ChatGPT crossed this threshold in June, with external data suggesting the milestone was confirmed in August.

Usage patterns within the Gemini app highlight a strong preference for audio interaction. According to background data, 63 per cent of Gemini users engage with the assistant via voice features, underscoring the shift in how consumers interact with large language models.

While specific performance benchmarks for Gemini 3.7 Flash are not detailed in the source material, the model’s release signals continued competition in the multimodal AI space. Independent verification of the model’s capabilities remains limited to Google’s own descriptions.
