The Trump administration has given OpenAI the green light for a broad launch of its advanced GPT-5.6 model, a source familiar with the situation confirmed to Axios Tuesday.

• OpenAI announced late Tuesday night that GPT-5.6 flagship model Sol, as well as lower tiers Terra and Luna, will launch publicly this Thursday.

Why it matters: The government and the world's most advanced AI companies are negotiating how people get access to powerful technologies case-by-case, in real time.

Oil markets are taking President Trump's claim that the Iran ceasefire is "over" seriously, but not literally.

Why it matters: The price jump is big, but even now, there are signs that the markets aren't expecting a complete return to war.

The Trump administration's official position about Venezuela's exiled opposition leader is simple: Don't help Maria Corina Machado gain entry to her home country. But Deputy Secretary of State Chris Landau didn't appear to get the memo.

• Landau is suspected of twice miscommunicating U.S. policy to two countries about Machado, according to seven senior administration officials.

Why it matters: Landau's alleged freelancing roiled the State Department for two days and led to internal arguments, international confusion and increased tensions with Machado supporters.
