Google Rolls Out Gemini 3 Flash as the Default AI Model
Gemini 3 Flash sets a new bar for performance vs. cost and speed.
Google has introduced Gemini 3 Flash, a more efficient version of its flagship Gemini 3 Pro model, delivering faster responses while preserving advanced reasoning capabilities.
Details:
Gemini 3 Flash replaces Gemini 2.5 Flash as the default model in the Gemini app and is also becoming the standard model behind AI Mode in Google Search.
The model builds on the reasoning, coding, and multimodal strengths of Gemini 3 Pro, while offering significantly lower latency, improved efficiency, and reduced operating costs.
Google says Gemini 3 Flash delivers more detailed and nuanced answers than its predecessor and can handle complex multimodal tasks, such as generating plans from videos and images, in seconds.
Despite its speed and efficiency, Gemini 3 Flash reportedly outperforms the previous flagship Gemini 2.5 Pro, while running at a fraction of the cost.
Gemini 3 Flash is also rolling out to developers through Google AI Studio, the Gemini API, Gemini CLI, Android Studio, Vertex AI, and other Google platforms.
With this release, Google is positioning Gemini 3 Flash as the workhorse model for daily AI interactions, balancing Pro-level reasoning with faster performance at scale.

OpenAI Launches AI Training Platform for Newsrooms
OpenAI has introduced a new learning initiative aimed at helping journalists and publishers understand and use AI tools more effectively in their daily work.
Details:
The new Academy for News Organizations is designed to provide on-demand training, practical workflows, and real-world examples tailored specifically for editorial teams.
The program was developed in collaboration with the American Journalism Project and the Lenfest Institute, bringing industry input into how AI is taught and applied in newsrooms.
Training materials focus on areas like research, translation, and productivity, alongside guidance for creating internal AI usage policies and editorial standards.
OpenAI says the goal is to help news organizations work more efficiently, allowing journalists to spend more time on reporting and less on repetitive tasks.
The initiative also addresses common industry concerns, including job displacement and the reliability of AI-generated content.
The platform builds on OpenAI’s existing partnerships with publishers such as News Corp and Hearst, with plans to expand the program further next year.
The launch comes as OpenAI works to strengthen relationships with the media industry, even as it faces ongoing copyright disputes with major publishers over AI training data.

Why AI Isn’t Replacing Affiliate Marketing After All
“AI will make affiliate marketing irrelevant.”
Our research shows the opposite.
Shoppers use AI to explore options, but they trust creators, communities, and reviews before buying. With less than 10 percent clicking AI links, affiliate content now shapes both conversions and AI recommendations.

OpenAI is now accepting submissions for ChatGPT apps, which will appear in a new app directory after review. These apps let users take actions directly inside chats, such as ordering food, and can be launched from the Tools menu or by using the “@” command. An SDK is available in beta, with the first approved apps expected to launch in early 2026.
OpenAI says apps must be suitable for general audiences and request only essential user data.
European AI startup Lovable has raised $330 million in a Series B round, valuing the company at $6.6 billion. The round was led by Google, with participation from Nvidia, HubSpot, and Deutsche Telekom. Lovable lets users build web apps using simple text prompts and has become one of the fastest-growing AI startups globally.
This upgraded document analysis model can handle cursive handwriting, dense forms, and complex tables. The company says it outperforms the previous version in 74% of cases and compares well with DeepSeek’s character recognition model. OCR 3 is available via API and Mistral’s Document AI platform.
The API lets developers build voice agents that support dozens of languages, call tools, and search real-time data.
The deal would involve OpenAI using Amazon’s AI chips, and if finalized, the investment could value OpenAI at over $500 billion, according to reports. The move would diversify Amazon’s AI bets alongside its backing of Anthropic and support its Trainium chip strategy via AWS.
That’s a wrap!
