According to monitoring by Beating, Romain Huet, the head of developer experience at OpenAI, revealed in a response to user inquiries on X that starting from GPT-5.4, the Codex model line (a series of programming-specific models previously maintained independently by OpenAI, distinct from the similarly named desktop application) has been merged into the main model, and will no longer be iterated separately. GPT-5.5 further enhances this integration, showing significant improvements in areas such as agentic coding (agent-driven autonomous programming) and computer use (manipulating computers to complete tasks). The practical impact of this merger for developers is that there is no longer a need to choose between a general model and a programming model; one model now encompasses dialogue, reasoning, and programming capabilities.

Trump: Does Not Believe Shooting Incident Related to Iran Conflict

On April 26, following a shooting incident at the White House Correspondents' Association dinner on April 25, U.S. President Trump has publicly experienced at least four assassination attempts against him. Here is a comprehensive summary: The first incident occurred on June 18, 2016, in Las Vegas, Nevada. A 20-year-old British man, Michael Sanford, attempted to seize a police officer's firearm to attack Trump at a campaign rally but was subdued on the spot without firing a shot. He was later sentenced to 12 months and 1 day in prison and deported. The second incident took place on July 13, 2024, in Butler, Pennsylvania. A 20-year-old man, Thomas Matthew Crooks, fired 8 shots from an AR-15 rifle from a rooftop approximately 130-160 yards away from the rally, grazing Trump's right ear. One rally attendee was killed, and two others were seriously injured; the shooter was shot dead by a Secret Service counter-sniper. This marked the first injury to a sitting or former U.S. president in an assassination attempt since Ronald Reagan in 1981. Following the incident, then-Secret Service Director Kimberly Cheatle resigned in accountability. The third incident occurred on September 15, 2024, in West Palm Beach, Florida. While playing at his golf club, Trump was targeted by 58-year-old Ryan Wesley Louse, who hid in bushes 300-500 yards away with a rifle. He was discovered and driven off by Secret Service agents, and the shooter fled without firing. He was later arrested and, in September 2025, a federal jury found him guilty of attempting to assassinate a presidential candidate among other charges. The fourth incident happened on April 25, 2026, during the White House Correspondents' Association dinner in Washington, D.C. This was Trump's first attendance at the dinner as president. During the event, 5-8 gunshots were heard near the main security checkpoint, prompting an emergency evacuation of Trump, Vice President Vance, First Lady Melania, and cabinet members, all of whom were unharmed. One Secret Service agent was shot but sustained no serious injuries due to wearing a bulletproof vest. The suspect, armed with a shotgun and a handgun, has been arrested, but their identity and motive have not yet been disclosed. The dinner will be rescheduled within 30 days. Among the four incidents, Trump was only injured in the Butler incident in July 2024; he was unharmed in the other three, all of which occurred within the protective perimeter of the Secret Service, raising repeated scrutiny of U.S. Secret Service security protocols. Media outlets like the BBC have previously described such incidents as part of a 'new normal' of political violence in America.

On April 26, after a senior U.S. military official stated to the Senate Armed Services Committee that the U.S. government operates a Bitcoin node, several members of the Bitcoin community questioned the government's understanding of the Bitcoin network. U.S. Navy Admiral Samuel Paparo told the Senate Armed Services Committee, "Our research on Bitcoin treats it as a computer science tool. It is a combination of cryptography, blockchain, and proof of work." Bitcoin educator and advocate Matthew Kratter remarked that the admiral sounded like he was reading from Bitcoin's 'Wikipedia page,' casting doubt on Paparo and U.S. Senator Tommy Tuberville's grasp of the protocol. Kratter added, "This is actually quite embarrassing. These two individuals are discussing something they do not understand. When he says it is a way to 'project power' or that it is a 'computer science tool,' he never really explains what he means." Kratter continued, "All I can think of is that they actually said nothing." The Rage reporter Lola Leetz described Paparo's Senate testimony as 'nonsense.' Sam Lyman, research director at the digital asset advocacy group Bitcoin Policy Institute, told Cointelegraph that the Iranian government is charging oil transit fees in stablecoins pegged to the dollar and Bitcoin, but prefers to use dollar-pegged stablecoins. Lyman pointed out that stablecoins can still be frozen by the issuer at the smart contract level, while Bitcoin cannot be frozen due to the absence of a central issuer. He stated, "This is one of the most significant scenarios for Bitcoin as a strategic asset." He added, "The reason Iran wants to use Bitcoin in these transactions is that no one can freeze Bitcoin, and no one can shut down the Bitcoin network."

On April 26, during the White House Correspondents' Association (WHCA) annual dinner, which took place on the evening of April 25 local time, President Trump made his first appearance at this century-old tradition as president. Trump had previously boycotted the dinner for four consecutive years during his first term (2017–2020), becoming the first sitting U.S. president to miss the event since Ronald Reagan was hospitalized due to an assassination attempt in 1981. That year, he held a rally in Pennsylvania instead, denouncing mainstream media as 'fake news.' He continued to miss the dinner in the first year of his second term (2025). Notably, Trump attended the dinner as a private guest in 2011 (the year Obama famously mocked him) and in 2015. On the eve of the dinner, over 250 journalists, including former CBS Evening News anchor Dan Rather, former ABC White House correspondent Sam Donaldson, and former NBC anchor Ann Curry, signed an open letter stating that Trump's 'systematic, ongoing, and unprecedented attacks on the press' made his attendance at the dinner 'deeply contradictory to the dinner's purpose,' and called for a 'strong response' from their peers. The dinner was ultimately interrupted due to a shooting incident, leading to the emergency evacuation of Trump and his cabinet members, with plans to reschedule within 30 days.
