Google's DiffusionGemma Generates Text 4x Faster by Ditching Sequential Tokens

Google closed out the week with five simultaneous launches spanning consumer apps, developer tools, and open research. The announcements touch nearly every layer of the AI stack, from a new audio model that translates speech in real time to an experimental open model that throws out the standard text-generation playbook entirely.

Real-time voice translation, finally

Gemini 3.5 Live Translate is Google's new audio model built specifically for live speech-to-speech translation. Unlike turn-by-turn systems that wait for the speaker to finish before responding, the model generates speech continuously, balancing the trade-off between waiting for context to improve quality and translating immediately to stay in sync with the speaker. The result is a conversation that flows without the awkward pauses that plague most real-time translation tools.

The model automatically detects 70+ languages and generates smooth, natural-sounding translated speech that preserves the speakers' intonation, pacing, and pitch. All audio output is watermarked with SynthID, Google's imperceptible audio watermark, to keep AI-generated content detectable.

The rollout is happening across multiple surfaces at once:

• Developers: Available now in public preview via the Gemini Live API and Google AI Studio
• Enterprises: Private preview in Google Meet this month, with support for 70+ languages and 2,000+ language pair combinations, up from the previous limit of five languages and English-only pairs
• Consumers: Rolling out now in the Google Translate app on Android and iOS globally

For Android users, a new listening mode lets you hear translations directly through your phone's earpiece, simply by holding your phone to your ear like a regular call. Grab, the Southeast Asian ride-hailing platform whose users make over 10 million voice calls per month, is already testing the model for multilingual driver-passenger communication.

NotebookLM becomes an actual research agent

Google has officially overhauled NotebookLM with powerful agentic capabilities, advanced multi-step reasoning, and an isolated coding environment. The upgrade shifts NotebookLM from a passive reading assistant into an active research partner that writes code, discovers sources, and builds project repositories from scratch.
