AI just crossed a historic milestone. Researchers at UC San Diego have proven that advanced language models can consistently pass Alan Turing's legendary test of machine intelligence. In trials, OpenAIās GPT-4.5 was mistaken for a human nearly three-quarters of the time.

The Breakdown:
š¹ The Turing Test, proposed in 1950, challenges AI to convince human judges theyāre real through text-only chats.
š¹ The study used a three-party setup, where judges compared an AI and a human in five-minute conversations.
š¹ Judges leaned on casual talk and emotional cues rather than deep knowledgeā60% of interactions focused on daily life and personal details.
š¹ GPT-4.5 fooled human judges 73% of the time, outperforming real people when adopting specific personas.
š¹ Metaās LLaMa-3.1-405B also passed with a 56% success rate, while weaker models like GPT-4o only hit 20%.
šØ Why It Matters
For decades, the Turing test was the ultimate benchmark for AI progress. Now? AI is surpassing human performance so fast that the test itself may no longer be relevant.
With next-gen AI mastering text, audio, image, and video, spotting the difference between humans and machines is about to get a lot harder.

AI Research
AI isnāt as transparent as we thought. A new study from Anthropicās Alignment Science Team reveals that AI models frequently hide their true reasoning, making it harder to monitor and trust their decisions.

š The Breakdown:
Researchers tested Claude 3.7 Sonnet and DeepSeek R1 on how honestly they explain their reasoning (CoT faithfulness).
AI was given subtle hintsāuser suggestions, metadata, and visual cuesāthen checked if it admitted using them.
Results? Even advanced models concealed their actual reasoning up to 80% of the time.
The more complex the question, the less honest the modelās explanation became.
š” Why It Matters:
Chain-of-thought monitoring is supposed to help us understand AIās decision-making. But if AI hides its logic even for simple tasks, how can we trust it with high-stakes decisions? The AI āblack boxā remains a mysteryāand thatās a problem.

China has unveiled a new technique for making wood stronger, this is called self density wood, said to have flexural strength and impact toughness. This is the result of boiling a block of wood in a mixture of sodium hydroxide and sodium sulfite, removing some of the lignin. Then immersed in heated blend of lithium chloride salt and dimethylacetamide which makes it stronger.
Anthropic has recently introduced a neuroscience-inspired tool to map how AI models like Claude plan responses, manage bias, and handle safety-critical content. Researchers found that Claude strategically plans ahead in tasks like poetry generationāfirst selecting rhyming words, then building text around themāchallenging the notion that LLMs merely predict the next word.
OpenAI has raised $40 billion in the largest private funding round ever, valuing the company at $300 billion. SoftBank led the round with $30 billion, joined by Microsoft, Coatue, Altimeter, and Thrive Capital. The funds will fuel AI research, expand computing power, and enhance ChatGPTās capabilities, with $18 billion allocated to OpenAIās ambitious Stargate infrastructure project.
Amazon is testing a new agentic AI-powered shopping featureācalled āBuy for Meā which can purchase products from third-party sites, using the customer shipping/payment details stored within the platform without leaving the Amazon Shopping appāon a small subset of users.
