Anthropic Beats OpenAI on Secondary Markets With $1 Trillion Implied Valuation

Anthropic has overtaken OpenAI in secondary market trading, with shares on platforms like Forge Global implying a valuation of around $1 trillion compared to OpenAI’s $880 billion. This marks a sharp reversal from just three months earlier, when Anthropic was valued at $380 billion following a major funding round. The surge has been driven by rapid revenue growth, with annualised figures jumping from $9 billion to $30 billion in a single quarter, largely due to strong enterprise uptake of its Claude Code and API products, alongside investor confidence boosted by backing from firms including Amazon.

Demand for Anthropic shares has also been intensified by limited supply, as early investors and employees have had few opportunities to sell, pushing prices higher in thinly traded markets. In contrast, OpenAI has seen more selling interest than buying on secondary platforms, keeping its valuation relatively stable. Despite the headline figure, the $1 trillion valuation reflects small, illiquid trades rather than a realistic public market price, with reports suggesting Anthropic may target an IPO valuation closer to $400–$500 billion, advised by Goldman Sachs and JPMorgan.

The tool is currently free for verified US-based physicians, nurse practitioners, physician assistants and pharmacists, with international expansion planned. It includes features such as a clinical search tool drawing on peer-reviewed literature, a deep research mode for medical reviews, reusable templates for administrative tasks like referral letters, and the ability to earn continuing medical education credits within the platform. Conversations are not used for model training, and the system is designed to support HIPAA compliance through appropriate agreements.

Alongside the launch, OpenAI introduced a new benchmark called HealthBench Professional to evaluate performance in realistic clinical tasks. The company reported that GPT-5.4 within the clinician version of ChatGPT scored higher than human doctors on this test, achieving 59.0 compared with 43.7 for physicians, even when humans were given unlimited time and internet access. It also outperformed competing AI models from other major developers. However, OpenAI noted the limitation that it designed both the product and the benchmark used to measure performance, which adds context to the results. Source


 

Tencent's New Hy3 AI Model Is the Most Efficient Chinese LLM No One's Talking About

Tencent has released Hy3 preview, a new open-source large language model designed to deliver strong performance in reasoning, coding and agent-style tasks while remaining highly efficient to run. The model uses a Mixture-of-Experts architecture with 295 billion total parameters but only around 21 billion active at a time, allowing it to reduce computational cost while maintaining strong capability. It also supports a very large context window of up to 256,000 tokens, enabling it to process extremely long inputs. Hy3 has already been integrated into Tencent’s ecosystem, including apps like QQ and Tencent Docs, and is available via Tencent Cloud with relatively low API pricing.

In benchmark testing, Hy3 shows major improvements over its predecessor, particularly in coding and autonomous task execution. On SWE-bench Verified, which measures real-world GitHub bug fixing, it improved from 53% in the previous version to 74.4%, placing it closer to leading global models. It also performed strongly on agent-based and web search tasks, with significant gains in benchmarks like BrowseComp and Terminal-Bench 2.0, reflecting better performance in multi-step, tool-using workflows.

White House Accuses China of 'Industrial-Scale' Theft From American AI Models

The White House has accused foreign actors, primarily in China, of conducting large-scale efforts to steal and replicate American artificial intelligence models. According to a memorandum from the Office of Science and Technology Policy, these campaigns allegedly use techniques such as jailbreak prompts, proxy accounts and coordinated networks of fake users to extract outputs from leading US AI systems. Officials claim the aim is to distil the capabilities of frontier models into smaller systems that can mimic their performance while avoiding the cost and complexity of developing them independently.

The administration says these so-called distillation attacks involve training smaller models on the outputs of larger, more advanced systems, which can allow imitators to achieve similar benchmark results at lower cost, even if overall capability is reduced. The memo warns that such activity could undermine security safeguards and weaken protections built into AI systems, and calls for closer cooperation between government and industry to prevent further exploitation. While acknowledging that legitimate model distillation can support open-source development, it argues that unauthorised copying of US AI technology represents a threat to innovation and will be met with stronger defensive and regulatory action.

Google Will Spend Up to $185 Billion This Year to Power AI 'Agentic Era': CEO

Google has announced plans to invest between $175 billion and $185 billion in 2026 to expand its AI and cloud infrastructure, as it accelerates its push into what CEO Sundar Pichai describes as the “agentic era” of artificial intelligence. Speaking at Google Cloud Next in Las Vegas, Pichai said the investment is aimed at supporting AI systems capable of performing tasks with limited human oversight, as the industry shifts from conversational chatbots to autonomous agents. He noted that nearly 75% of new code at Google is now AI-generated but still reviewed and approved by engineers.

The company also highlighted how it is already using AI internally to automate workflows, including cybersecurity operations where AI systems process large volumes of threat reports and significantly reduce response times. Alongside the infrastructure spending, Google is building an ecosystem around agentic AI through partnerships and a $750 million fund to support cloud partners and enterprise adoption. Companies such as Citi and Thinking Machines Lab are already using Google’s tools for financial services and AI research, reflecting the company’s broader strategy to monetise and scale agent-based systems across industries.

OpenAI Just Open-Sourced a Tool That Scrubs Your Secrets Before ChatGPT Ever Sees Them

OpenAI has released a lightweight, open-source tool called Privacy Filter that removes sensitive personal information from text before it is sent to AI systems. The model, which has around 1.5 billion parameters, runs locally on a user’s device and is designed to detect and mask data such as names, addresses, emails, phone numbers, passwords and account numbers. It is available under the Apache 2.0 licence via GitHub and Hugging Face, meaning it can be freely used, modified and integrated into other products.

The tool works by analysing the full context of a sentence rather than relying on simple pattern matching, allowing it to better distinguish between genuine personal data and similar-looking non-sensitive information. OpenAI reports that it achieves around 96% accuracy on a standard benchmark for identifying and masking personal data. Because it runs locally, the idea is that users can clean their text before sharing it with chatbots, reducing the risk of exposing sensitive information to external systems. However, OpenAI cautions that it is not a complete privacy solution and should not be treated as a substitute for formal compliance or security processes. Source


 

Anthropic's Claude Mythos AI Finds 271 Vulnerabilities in Firefox—Yes, It's Seriously Powerful

Mozilla has reported that an early version of Anthropic’s Claude Mythos AI model identified 271 vulnerabilities in its Firefox browser during internal testing. The findings, which have since been patched, highlight the model’s ability to analyse large and complex codebases and detect security flaws that would typically require significant human expertise. Mozilla also referenced earlier tests in which the same system found dozens of additional security-sensitive bugs, suggesting a substantial increase in automated vulnerability discovery capability.

The results have raised both optimism and concern within the cybersecurity community. On one hand, such tools could help developers identify and fix weaknesses before they are exploited, potentially shifting the balance towards defenders. On the other hand, experts warn that the same capabilities could be used to accelerate cyberattacks by automating the discovery of exploitable flaws at scale. Anthropic has restricted access to Claude Mythos through a controlled programme for selected partners due to these risks, as governments and industry groups continue to assess the security implications of highly capable AI systems.

Google Fixes AI Coding Tool Flaw That Let Attackers Execute Malicious Code: Report

Google has fixed a security vulnerability in its Antigravity AI coding platform after researchers discovered that it could potentially allow attackers to execute malicious commands on a user’s machine. The flaw, reported by cybersecurity firm Pillar Security, involved a prompt injection issue in the platform’s file search tool, where unvalidated user input could be passed directly to a command-line utility. This could turn what appeared to be a harmless search request into an opportunity to run system commands.

Researchers warned that the issue could bypass Antigravity’s Secure Mode, meaning attackers might still be able to trigger actions even under stricter security settings. In a demonstration, they showed how a crafted script could be executed through the system’s search function, highlighting the risk of AI development tools interpreting hidden instructions as legitimate commands. Google was notified of the issue in January and released a fix on 28 February. The findings underline broader concerns about prompt injection attacks in AI coding systems, where autonomous or semi-autonomous tools can be manipulated into performing unintended and potentially harmful actions.
