According to three people familiar with the matter, OpenAI is preparing to launch a new model series tentatively named "Astra", which will feature enhanced capabilities for completing long-cycle tasks. OpenAI founder Sam Altman presented Astra to policymakers and regulators in Washington this week. Reportedly, OpenAI touts that the model enables multiple AI agents to collaborate over extended periods to solve highly complex problems, with applications in projects or advanced mathematical tasks. Astra will be a new category of models for OpenAI, following Sol, Terra, and Luna. It remains unclear when OpenAI plans to release the model. The company has also not yet decided whether to brand Astra as GPT-6 or an add-on to the GPT-5 series, such as GPT-5.7. According to one insider, while the models are already in testing, they are expected to be among the first AI models submitted under a new framework planned by the Trump administration, which requires AI models to be filed with the federal government before public release. The administration has set a self-imposed deadline of the end of this week, aiming to finalize the framework by then. Reportedly, OpenAI also plans to release a report in the near term detailing how it solved 10 previously unsolved mathematical problems, to showcase the capabilities of its most advanced AI.

Former U.S. Congressman George Santos has reached a settlement with the U.S. Commodity Futures Trading Commission (CFTC). The CFTC alleges that Santos engaged in manipulative trading practices while trading a prediction market contract on Kalshi related to whether he would attend the February 2026 State of the Union address, earning over $17,500 in profits from the activity. According to the CFTC’s Friday announcement, Santos is required to pay $35,000 as part of the settlement, though he neither admitted nor denied the regulator’s findings.

According to crypto journalist Eleanor Terrett, the Trump administration is weighing a bipartisan ethics counter-proposal introduced by Senator Tillis and Representative Gallego. The bill would grant state attorneys general new authority to sue the Department of Justice if the DOJ fails to enforce ethics laws against federal officials. The Clarity Act, a bipartisan cryptocurrency market structure bill that has cleared Senate committee review and includes a stablecoin revenue compromise provision, may see its fate hinge on the White House’s response to the ethics proposal this weekend—a response that will determine whether to advance a cloture vote. If an ethics compromise is reached, the Clarity Act is expected to move forward, delivering regulatory clarity such as Bank Secrecy Act exemptions for non-custodial developers; otherwise, parts of the GENIUS Act could be triggered, leading to heightened regulatory uncertainty for stablecoins.
