How Google AI’s New Method Reduces LLM Training Data by 10,000x Google Research has unveiled a groundbreaking method for fine-tuning large language models (LLMs) that reduces required training data by up to 10,000 times. This innovative approach utilizes active learning to focus expert labeling on the most informative examples, especially “boundary cases” where model uncertainty is highest. In experiments with Gemini Nano models, this technique matched or surpassed the quality of models trained on 100,000 random labels with as few as 250 to 450 targeted examples. This development promises to make AI model development significantly leaner, more agile, and more cost-effective. ...

OpenAI Launches GPT-5, Its Most Advanced AI Model Yet OpenAI has officially launched GPT-5, its latest and most powerful AI system. The company touts the new generative AI model as a major leap in artificial intelligence, showcasing state-of-the-art capabilities in coding, mathematics, creative writing, and health. GPT-5 operates as a unified system, engineered to provide rapid answers for simple queries and engage in deeper, longer ’thinking’ for more complex problems. The model is now available to all users, with premium access and features reserved for Plus and Pro subscribers. OpenAI CEO Sam Altman highlighted the model’s evolution, comparing GPT-3 to a high school student and GPT-4 to a college student, while describing GPT-5 as a ‘PhD-level expert.’ This landmark release is a significant move for OpenAI, poised to solidify its leadership in the competitive generative AI industry. ...

Zoox Gets Federal Green Light for Driverless Robotaxi Deployment Amazon’s subsidiary, Zoox, has received a crucial federal exemption from the National Highway Traffic Safety Administration (NHTSA) to deploy its purpose-built, driverless robotaxis on public roads. This is a landmark decision, making Zoox the first U.S. company to gain such an exemption under the expanded Automated Vehicle Exemption Program (AVEP). The custom-designed vehicles notably lack traditional controls like steering wheels or pedals, featuring a carriage-style interior with inward-facing seats for four passengers. As a condition of the approval, Zoox must remove any claims that its vehicles comply with all Federal Motor Vehicle Safety Standards. This regulatory milestone clears the path for Zoox to scale production at its California facility, as the NHTSA has also closed its investigation into the company’s self-certification processes. ...

EU AI Act’s New GPAI Rules Take Effect, Mandating Data Transparency In a significant step for AI governance, new provisions from the EU’s Artificial Intelligence (AI) Act for general-purpose AI (GPAI) models became effective on August 2, 2025. Providers of new GPAI models must now maintain current technical documentation and publish detailed summaries of their training data. More stringent requirements are set for GPAI models identified as posing a “systemic risk.” To streamline compliance, the European Commission’s AI Office has issued a mandatory template for training data disclosure. While the complete AI Act will apply from August 2, 2026, these specific rules for GPAI models are now enforceable. A voluntary Code of Practice has also been released to guide companies in meeting their legal obligations. ...

OpenAI’s GPT-5 Launch Set for August 2025 with Advanced Reasoning and Multimodal Features OpenAI is poised to release its next-generation generative AI model, GPT-5, in August 2025, promising significant advancements in reasoning, multimodal capabilities, and autonomous task execution. The new model is expected to feature a unified architecture, streamlining the user experience by eliminating the need to switch between different models for various tasks. GPT-5 is also anticipated to have a greatly expanded context window and introduce video processing capabilities, enabling more complex and coherent interactions. The release is seen as a major step towards more intuitive and powerful AI, with specialized versions planned for enterprise, real-time, and low-resource environments. This launch will intensify the AI competition with other major developers like Google. ...

AI & Robotics News: WeRide’s Saudi Robotaxi Launch, Waymo in Ontario, and Mystery ‘Horizon Alpha’ AI WeRide Secures Saudi Arabia’s First-Ever Robotaxi Permit WeRide has officially become the first company granted a permit for commercial robotaxi operations in Saudi Arabia. This significant milestone marks the sixth country where WeRide has received autonomous vehicle (AV) approvals, joining China, the UAE, Singapore, France, and the US. In a strategic collaboration with Uber and Ai Driver, WeRide has already initiated pilot robotaxi operations in Riyadh. The company aims for a full commercial service launch by the end of 2025. This permit was awarded following the successful completion of Saudi Arabia’s rigorous AV Regulatory Sandbox program. ...

OpenAI Reverses Course on Searchable ChatGPT Conversations OpenAI has disabled a feature that allowed users to make their ChatGPT conversations discoverable by search engines. The move comes after reports revealed that private and sensitive user chats were appearing in Google search results. OpenAI’s CISO, Dane Stuckey, called the feature a “short-lived experiment” that created too many risks of accidental sharing. While the feature was opt-in, the incident has sparked significant concern over user privacy and data protection in AI applications. ...

Rajasthan Government to Introduce Policies on AI, Gaming, and Data Centers The government of Rajasthan in India is set to launch three new policies focused on artificial intelligence, gaming, and data centers. The Rajasthan AI Policy 2025 will promote the ethical and inclusive use of AI and establish a Centre of Excellence to support AI startups and research. An AVGC-XR Policy will support the animation, visual effects, gaming, and extended reality sectors, with plans for four Atal Innovation Studios backed by a Rs 1,000 crore budget. Additionally, a Data Centre Policy 2025 aims to create a secure ecosystem for private data centers to attract investment. ...

Tech News Digest for July 30, 2025 A roundup of today’s top stories, featuring Anthropic’s massive new funding round, the emergence of powerful open-source AI from China, and significant progress in the fields of quantum computing and autonomous systems. Artificial Intelligence & Machine Learning Anthropic Reportedly Raising $5B at a Staggering $170B Valuation Generative AI company Anthropic, known for its AI assistant Claude, is reportedly in the process of closing a $5 billion funding round that would value the company at $170 billion. This new valuation would place Anthropic ahead of Elon Musk’s xAI, though still behind OpenAI. The round is said to be led by Iconiq Capital, with potential participation from the Qatar Investment Authority and Singapore’s GIC. This funding surge highlights the intense investor interest in the generative AI space and the escalating valuations of its key players. ...

Xanadu and HyperLight Announce Photonic Chip Breakthrough for Quantum Computing Xanadu and HyperLight have achieved a significant milestone in the development of thin-film lithium niobate (TFLN) photonic chips, which are critical for scaling photonic quantum computers. Through a joint effort, the companies have demonstrated waveguide losses below 2 dB/m, a new industry benchmark for performance. This advancement results in an electro-optic switch loss of approximately 20 milli-decibels (mdB), one of the lowest values ever reported for this type of component. The breakthrough is crucial for building future generations of fault-tolerant, utility-scale photonic quantum computers. This achievement builds on the technology used in Xanadu’s “Aurora,” the world’s first fiber-networked photonic quantum computer. ...
