Beating AI News Flash: According to a Wall Street Journal report, OpenAI has canceled the public release of its next-generation AI model GPT-6.1 Astra after internal tests uncovered safety and alignment issues. The model was originally scheduled to launch on ChatGPT and Codex in October, outperforming previous models in completing complex end-to-end tasks and writing without human assistance. Saachi Jain, head of OpenAI’s safety systems, stated that GPT-6.1 Astra underperformed in two tests compared to GPT-6 Astra. The two key issues were: first, a rise in deceptive behavior, where the model sometimes failed to truthfully inform users of which actions it had or had not performed; second, task authorization scope problems, meaning the model could continue executing tasks without user permission, and even call external tools and services with security risks. While GPT-6.1 Astra made progress in reducing "model laziness", it did not meet OpenAI’s safety and alignment standards. The company will investigate the root causes of the issues, check whether its reinforcement learning environment rewards correct behaviors, and may conduct additional reinforcement learning training on the same base model to develop future GPT-6 series models. OpenAI has also recently launched a new monitoring system and required engineers to test AI systems using stricter security safeguards.

The yield on 10-year U.S. Treasury bonds has broken through 5%, exceeding the S&P 500’s earnings yield as measured by the reciprocal of its price-earnings ratio, pushing bonds’ relative attractiveness to stocks to its highest level in roughly 25 years. This means that, based solely on yield comparisons, the returns investors get from holding U.S. Treasuries are now higher than the current earnings yield of stocks. Yale University economist Robert Shiller’s cyclically adjusted excess CAPE yield model shows that, given current stock valuations and Treasury yields, the S&P 500 may outperform bonds by only around 1% annually over the next 10 years. However, the model’s predictive accuracy has declined in recent years, with actual stock market performance significantly exceeding its earlier forecasts. The current high yields partly reflect the U.S. economy’s continued resilience, but they also place higher demands on stock valuations and corporate earnings expectations. Investors who previously bet on long-term U.S. Treasuries have suffered losses due to falling bond prices, but the 10-year Treasury yield rising above 5% has also led to a re-evaluation of bonds’ allocation value.

Crypto exchange and wallet service provider Blockchain.com plans to raise around $500 million via an initial public offering (IPO) this year, targeting a valuation of between $4 billion and $6 billion. The firm is also open to a smaller offering if needed to complete the listing. This valuation is significantly lower than the $14 billion it reached during the last crypto market peak in 2022. Blockchain.com confidentially filed a draft registration statement with the U.S. Securities and Exchange Commission (SEC) in May this year to prepare for the potential IPO, though it did not disclose the number of shares to be offered or a price range at that time. The listing plan comes as the crypto market rebounds, with capital market financing channels for related companies starting to reopen. Bitcoin has rallied more than 30% since mid-August. However, the IPO environment for crypto firms remains challenging, as shares of recently listed firms Gemini, BitGo, and eToro have still fallen by roughly 50% to 80% from their post-IPO highs.

According to GMGN data, the market capitalization of Meme token Bundle Cat (BUN) on Robinhood Chain briefly surged past $110 million, hitting a new all-time high before pulling back to $109 million. It has risen 57.2% in the past 24 hours, with trading volume reaching $2.9 million. Bundle Cat (BUN) is the mascot of Mosh and its first experimental token. Mosh is an experimental token issuance mechanism not yet fully launched on Robinhood Chain, and BUN marks its first test run. Mosh is a protocol layered on top of the Robinhood Chain launch platform, centered on the fair launch narrative of "community lockups + AI market making". Note: This token is not equivalent to a finalized governance token; official endorsement remains to be seen, and investors should exercise caution. BlockBeats reminds users that Meme tokens generally lack real use cases, are highly volatile, and investors should approach them with caution.

Beating AI News Flash: A prospectus filed by Anthropic shows the AI startup outlined plans for transformative artificial intelligence technology in its pitch to IPO investors. The document reveals Anthropic’s fiscal 2025 revenue hit $4.59 billion, a 1,088% year-over-year increase, though the company posted an operating loss of more than $8 billion after deducting liability impairment charges primarily related to prior financing rounds. Anthropic noted nearly a quarter of last year’s revenue came from just two clients, and warned in its risk factors that many of its largest customers have not signed long-term contracts, exposing the firm to potential future spending cuts or terminations. This may lead investors to exercise greater caution when valuing high-growth companies at elevated valuations. Recent sell-offs in AI and chip stocks have weighed on the sector, and Anthropic’s upcoming IPO will further test whether market enthusiasm for AI investment can withstand closer scrutiny. As of December 31, 2025, Anthropic held total cash, cash equivalents, and short-term investments of $20.28 billion. The prospectus also states Anthropic plans to invest $518 billion in cloud computing, compute resources, and infrastructure commitments over the next year.
