GOOGLE'S AD MONOPOLY UNDER MICROSCOPE AS JUDGE WEIGHS REMEDIES

The Justice Department has asked a US District Judge to order Google to divest AdX, an advertising exchange. It claims the divestiture would enable meaningful change. Google claims that it would be a radical solution that would remove the company from the advertising-exchange business completely. Google plans to appeal the ruling that it violated the law.

WHY WE BUILT THE RESPONSES API

OpenAI argues its new Responses API is part of the inevitable evolution from turn-based chats to persistent agentic reasoning that maintains state across conversation turns. The company claims GPT-5 achieves 5% better performance on TAUBench through preserved reasoning state and reports 40-80% improved cache utilization. It also adds hosted tools so developers don't have to build their own retrieval pipelines from scratch.

HOW I USE AI

AI coding requires a mindset shift, emphasizing ownership of AI-generated code and exploiting opportunities for maximum efficiency. Success lies in treating AI coding like management, focusing on creating and leveraging productive gradients where minimal effort yields significant rewards. Junior engineers might have an advantage over seniors in adapting to this new role, as embracing AI demands stepping out of comfort zones and fostering a strong sense of responsibility.

TOOL CALLS ARE EXPENSIVE AND FINITE

Tool calling is many orders of magnitude more costly than calling a plain old function from code. People should design their agentic systems according to the limit on how many tool calls their agents can effectively make. Using a tool call to add two numbers once probably doesn't matter, but scaling the problem up to 1,000 numbers will require a long wait and may exceed context window limits. Calling a function many times in a loop is one of the most common ways to solve a problem with code.

LMARENA HAS SOME COMPETITION: SCALE AI LAUNCHES SEAL SHOWDOWN, A NEW BENCHMARKING TOOL

Seal Showdown is a new benchmarking tool that allows users to test various AI models head-to-head and vote on which one performs better. Unlike LMArena, it captures real preferences to more closely reflect how everyday users feel about various models. Rankings are derived from conversations on Scale's Outlier platform, so each user's country, education level, profession, language, and age can be verified. This allows the platform to show which models are most popular according to specific regions, languages, ages, and use cases.

DEEPMIND AI SAFETY REPORT EXPLORES THE PERILS OF “MISALIGNED” AI

DeepMind recently released the third version of its Frontier Safety Framework, which explores how generative AI systems can become threats. The safety framework details critical capability levels for assessing AI models that define the points at which behavior becomes dangerous. It also discusses ways for developers to address these risks. Misaligned AIs may ignore human instructions, produce fraudulent outputs, or refuse to stop operating when requested. For now, developers can prevent this by monitoring AI's chain of thought outputs, but future models may hide their reasoning, making it impossible to determine with certainty that a model is working against the interests of its human operator.

CHINA ASKS BROKERS TO PAUSE RWA TOKENIZATION IN HONG KONG

China's securities regulator (CSRC) has informally advised some domestic brokerages to halt their real-world asset (RWA) tokenization business in Hong Kong, citing risk management concerns. The move comes as Hong Kong positions itself as a global hub for digital assets, with 77 firms expressing interest in stablecoin licenses, even while Beijing maintains a cautious stance. The CSRC's pause reflects worries about firms making claims without sufficiently strong backing, amid a booming RWA market that could reach $2 trillion by 2030.

UNREPORTED ATTACK ON CRYPTO.COM LEAKED USERS' PERSONAL DATA

A teenage hacker named Noah Urban from the cybercriminal gang Scattered Spider, along with an accomplice called Jack, successfully gained access to a Crypto.com employee account through phishing attacks targeting telecommunications, technology, and cryptocurrency company staff. The breach occurred before March 2023, when Urban was targeted in an FBI raid that seized $4 million worth of cryptocurrency plus hundreds of thousands in cash and jewelry. Urban was later arrested in January 2024 and sentenced to 10 years in prison after pleading guilty to involvement in hacks of 13 companies. Crypto.com confirmed to Bloomberg that the breach affected "a very small number of individuals" with no customer funds accessed. Blockchain sleuth ZachXBT criticized the exchange for failing to disclose the breach and noted that it has been breached several times.

MARKETS RECEIVE RISK-ON SIGNAL

The Federal Reserve's 25 basis point rate cut, accompanied by guidance for further easing, has bolstered risk-on sentiment and created a supportive environment for risk assets in the near term through this dovish monetary policy stance. Digital Asset Trusts are showing signs of mid-to-late cycle maturation as market Net Asset Values compress and confidence wavers despite new product launches, indicating that premiums are increasingly dependent on overall market momentum rather than fundamental value propositions. Ethereum is experiencing improved demand dynamics coupled with constrained sellable supply, as the Kiln-driven exit queue is temporarily trapping staked ETH and creating long-biased positioning in the market. The potential introduction of a Base token is under consideration, which could have significant implications for the Coinbase L2 ecosystem and broader market dynamics.

SOL TRADING BOTS LOSE $96M IN 6 WEEKS

Trading bot wallets on Solana have reduced their SOL holdings by 435K tokens (~$96M) over the past six weeks, marking a 24.6% decline. The sharpest drop came from Axiom, down to 390K SOL, while Photon and GMGN also saw significant decreases. This shift suggests bots may be deleveraging or reallocating capital, raising questions about liquidity dynamics in Solana's high-frequency trading ecosystem.

THE RIGHT SIZE PROJECT

Freelancers and small agencies should focus on "right-sized" projects rather than chasing big jobs they're not ready for. The key is delivering 10× ROI by charging clients 10% of the value created—for example, charging $1,000 for work that generates $10,000 in revenue or savings. Success comes from starting with smaller projects where you can guarantee outsized results, then gradually scaling up as you build proof and confidence in delivering larger value.
