first_img OpenAI terminates the Cursor model contract, Musk criticizes Altman

OpenAI has notified SpaceX that it will terminate the contract to provide models for the AI coding tool Cursor it acquired, with a suggested termination date of November 12, stating that this is the longest notice period stipulated in the contract. OpenAI expressed that the decision was difficult, as it values the widespread use of its models by developers, but due to Musk's past breaches of contract, it does not trust SpaceX to use the technology as agreed, and mentioned issues related to the use of OpenAI models during xAI training and contract problems when acquiring X.Musk stated on X that he does not care at all and referred to Sam Altman and Greg Brockman as frauds, accusing them of stealing from an open nonprofit organization. Musk was a co-founder of OpenAI but later filed a $150 billion lawsuit against OpenAI and lost due to exceeding the deadline. OpenAI had attempted to acquire Cursor's developer Anysphere but was unsuccessful, while SpaceX acquired Cursor for $60 billion, with the merger completed on August 15.Michael Truel, co-founder of Cursor and now an executive at SpaceX, stated that Cursor views the OpenAI platform as neutral infrastructure and is negotiating with OpenAI, noting that OpenAI models account for 5% of Cursor's user traffic. Tom Brown, co-founder of Anthropic, stated that they will continue to expand computing power to provide the Claude model on Cursor.

Forbes: Europe is accelerating the construction of alternatives to the US dollar stablecoin, with the digital euro and private stablecoins advancing on two fronts

As the US dollar stablecoin continues to dominate the on-chain payment market, Europe is accelerating the development of a digital currency system that reflects its own regulatory framework, monetary sovereignty, and privacy standards, gradually forming two parallel paths: "digital euro + private euro stablecoin." Among them, the European Central Bank is prioritizing privacy protection as an important design focus for the digital euro. Piero Cipollone, a member of the Executive Board of the European Central Bank, stated that the digital euro will provide the highest possible level of privacy under current technological conditions, with offline payments visible only to the payer and payee; in online transactions, the euro system cannot directly identify specific individuals, but banks can still obtain the information required for anti-money laundering.At the same time, private institutions have taken the lead in promoting euro stablecoins. Revolut has begun rolling out EURR to some users in Denmark, Poland, and Portugal, with plans to expand to the entire European Economic Area in the future. EURR operates on Ethereum and is issued by Bridge Building, a subsidiary of Stripe, aiming to maintain a stable value against 1 euro. Forbes points out that the digital euro and EURR are not simply in a substitutive relationship: the former is a public currency issued by the central bank, while the latter is a privately issued on-chain stablecoin. The European digital currency market is developing along these two models simultaneously, with competition focusing on privacy, usability, regulatory clarity, and actual economic value.

first_img SemiAnalysis: HBF non-HBM alternative, cost and heat dissipation still have uncertainties

P Equity Research and SemiAnalysis researcher Nick Doyle and others discussed high bandwidth flash (HBF) in X Space. Nick stated that it is still too early to determine how much the cost premium of HBF relative to HBM can shrink; existing data mostly comes from vendor claims, such as Sandisk stating that the cost per bit is about one-eighth that of HBM. Yields, testing, and other factors will improve with scale, but structural costs such as TSV, stacking, and pSLC mode will always exist, and durability is a key unknown; if wear exceeds expectations, costs will rise.The application scenarios for HBF are narrow, targeting only AI inference, especially low batch and long context MoE models, and it is not a substitute for HBM. The actual bandwidth target is about 1.6 TB/s, which is at the HBM3E level, suitable for sequential reads to load model weights, more aligned with the capacity needs of a small number of GPUs in local or private enterprises, rather than ultra-large-scale bandwidth scenarios. Heat dissipation reliability has not yet been resolved; flash memory will degrade faster at high temperatures next to GPUs, and mitigation measures such as UCIe separation and daily refresh have yet to be validated.In terms of manufacturing, Sandisk/Kioxia has experience with 3D NAND, and SK Hynix complements HBM-style stacking capabilities, but mass production is still to be confirmed. Overall, storage is shifting towards a specialized layered market, with NAND shortages expected to continue until 2028, and HBF may further impact supply and demand.
