According to market sources, AI firm DeepSeek is issuing refunds to all its API users, with the refund amount equal to the total usage fees users incurred on the DeepSeek API platform over the past three days. Earlier today, DeepSeek experienced a 5-hour service outage before restoring operations. The refund initiative is likely linked to the prolonged service disruption the platform faced today, while the specific cause of the outage and detailed refund arrangements remain to be officially confirmed.

Beating AI News (Dongcha) reports that developer Guru, after using the WHOOP fitness tracker for 18 months, decided to cancel his subscription while keeping the device. He modified the community project NOOP into his own iPhone app Zhoop, allowing him to continue accessing heart rate, step count, and sleep data without relying on WHOOP’s servers. He also integrated this data into his personal health AI agent. WHOOP’s annual U.S. membership ranges from $199 to $359; once users stop paying, they lose access to the brand’s core official health analysis services. This solution does not require modifying the tracker’s firmware. NOOP first emerged back in June this year, with developers reverse-engineering WHOOP’s Bluetooth communication protocol to enable direct reception of sensor data on mobile devices, then using public algorithms to calculate metrics including sleep, heart rate variability, and physical recovery. Guru adopted this underlying code, added features such as diet tracking, calorie deficit calculation, and weight loss planning, and redesigned the interface to suit his needs. Guru believes AI has broken the software lock-in that manufacturers impose on their hardware.

According to Digital Asset, South Korean crypto influencer "Coin King Jonbur Kim" has been acquitted by the Seoul Southern District Court over his alleged involvement in a crypto scam worth 340 billion won (approximately $253 million). The court announced Thursday that the prosecution’s evidence was insufficient to prove his guilt. The influencer’s real surname is Park; he was previously accused of involvement in issuing and launching fraudulent tokens, spreading false information, and manipulating coin prices in cases involving projects such as Podo Coin and Artube. The court’s ruling holds that existing evidence is insufficient to support the relevant criminal charges.

US September CPI rose 0.6% month-over-month and 3.7% year-over-year, both exceeding expectations, yet Treasuries saw no sell-off. On Thursday, the US 10-year Treasury yield fell as much as 8.4 basis points to 5.105%, hitting a three-week low. Ongoing declines in AI tech stocks and rising associated credit risks drove capital back into Treasuries, outweighing rate-hike fears sparked by hotter inflation. Market concerns are spreading from overvalued AI stocks to the debt financing model for data center construction. Data center operator CoreWeave’s debt financing size is nearly $48 billion, with some of its bond yields rising to around 15% to 16%, sparking concerns over the AI sector’s debt-servicing capacity and private credit risks. BlackRock has downgraded its rating on US equities to "neutral", while upgrading its outlook on Treasuries and showing a preference for short-term Treasuries. Analysts note that recent trends show Treasuries are regaining their safe-haven status during stock market declines, suggesting the traditional stock-bond hedge relationship may be recovering. However, US inflation remains above the Fed’s 2% target, and fiscal deficit and Treasury supply pressures have not abated, so whether Treasuries can sustain their safe-haven function remains to be seen.

Beating AI News Flash: OpenCode has announced limited-time free access to DeepSeek V4.1 Flash. Users can now select "DeepSeek V4.1 Flash Free" from the model list, with no charges for input and output tokens. However, the free version only offers a 200,000-token context window, an 80% reduction from the paid version’s 1 million tokens. When handling large code repositories or long-running coding agents, the free version is more prone to hitting the context limit. DeepSeek V4.1 Flash was already integrated into OpenCode as early as September 10. On October 12, OpenCode had just raised the V4.1 Flash usage quota in its $10 monthly Go plan to a value of $80, and has now added a separate free tier. OpenCode’s official documentation confirms this free access is time-limited, though no end date has been disclosed. The platform also promises the free tier follows a zero-data-retention policy, and will not use user content for model training.
