Google to Open Source Gemma 4 Model Soon, DeepMind CEO and Team Members Simultaneously Tease

According to 1M AI News monitoring, Google DeepMind CEO Demis Hassabis made a post on X with four diamond emojis (????), while Google tech team member and leader of Google AI Studio and Gemini API, Logan Kilpatrick, had earlier posted only a word "Gemma." The two posts almost simultaneously are widely interpreted as a signal that Google is about to release the open-source model Gemma 4.

Signs of a leak had appeared earlier. An anonymous model with the codename "significant-otter" showed up on the LMSYS Chatbot Arena and, when questioned about its identity by users, claimed to be "I am Gemma 4, a large language model developed by Google DeepMind." User feedback from the Reddit community r/LocalLLaMA indicated that the model has quick response times, is not an inference model, and has passed community-standard benchmark tests for foundational capabilities.

Google has not yet officially announced Gemma 4. Its predecessor, Gemma 3, was a lightweight model family from Google aimed at the open-source community, supporting single GPU or TPU operation, with multilingual, multimodal, and long-context capabilities, and had a strong reputation in the open-source community.
