SynthID

Google has moved its SynthID AI content detector from limited early access to global availability in English. The tool now covers content from OpenAI, Nvidia, Kakao and, "soon," Apple Intelligence, in addition to Google's own Gemini models.

OpenAI will switch on invisible text watermarks called textGrain for ChatGPT and Codex users in the EU over the coming weeks. API watermarking will be opt-in worldwide, unlike Anthropic's mandatory approach for Claude. OpenAI's own data shows detection drops sharply when text is edited.

Google has added Live Avatar to its Gemini 3.8 Live dialogue models, pairing real-time video personas with voice AI for enterprise customer service and sales use cases. The feature is restricted to Gemini Enterprise customers via allowlisting and includes SynthID watermarking on all generated video.

Google DeepMind has added Live Avatar, a real-time video avatar capability, to its Gemini 3.8 Live conversational model. The feature is available now in Gemini Enterprise, supporting lip-synced, expressive avatars across 97 languages with background tool calling.

Google DeepMind has released Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS, text-to-speech models that generate custom voices from natural language prompts and support line-by-line performance direction. The models top Hume AI's Voice Design Benchmark at 71.4 and claim first and second place on its Overall Quality Index.

OpenAI has released GPT-Image-2.5 in two variants — Flare and Sunburst — promising faster generation, more precise multi-step editing, and new 'xhigh' and 'max' quality tiers. Both models use identical token pricing but land at the top of Arena's preliminary text-to-image leaderboard.

Anthropic is rolling out a watermark verification API that lets approved regulators, media outlets, fact-checkers, and enterprises check whether text was generated by Claude. The system builds on Google's SynthID text method and responds to EU AI Act watermarking requirements in effect since August 2, 2025.

Anthropic has begun watermarking text and images generated by Claude to comply with EU AI transparency regulations. The method embeds an undetectable pattern during word selection that can be decoded via API, without affecting output quality, speed, or cost.

Anthropic is rolling out a watermark detection API that lets third-party developers check whether text was generated by Claude. The move stems from EU AI Act compliance requirements and uses a variant of Google DeepMind's SynthID Text method.

Google VP Josh Woodward announced a new toggle that lets users remove visible sparkle-icon watermarks from AI-generated content made with Nano Banana, Omni, and Lyria. The invisible SynthID watermark and C2PA metadata will remain unaffected, and the toggle won't roll out in the EU or South Korea where visible labeling is legally required.

Google now lets users toggle off the visible "sparkle" watermark on content generated with Gemini and Flow, including Nano Banana and Omni model outputs. Invisible SynthID watermarks and C2PA metadata still remain embedded, according to Google Labs VP Josh Woodward.

Google announced users can now toggle off visible watermarks on AI-generated images, video, and songs from its Nano Banana, Omni, and Lyria models. Invisible SynthID watermarks and C2PA metadata remain in place for transparency.

Gemini 3.7 Flash has replaced 3.6 Flash in the Gemini app's model picker on Android, iOS, web, and macOS, following its debut in the Spark agent a day earlier. The app also now lets users turn off visible corner watermarks on AI-generated images, video, and music.

Google has released Gemini 3.1 Flash Lite Image, a text-to-image model that generates 1K resolution images in approximately 4 seconds — 2.7× faster than Gemini 3.1 Flash Image. The model is priced at $0.25 per 1M input tokens and $1.50 per 1M output tokens, with a 66K context window and knowledge cutoff of January 2025.

Google has released Gemini Omni Flash, the first model in its new Gemini Omni family designed to generate video content from text, images, video, and audio inputs. The model is available now to AI Plus subscribers, with free access coming to YouTube Shorts and YouTube Create later this week.
