Summary: OpenAI dropped GPT 5.1 yesterday, and Sam Altman's announcement was surprisingly... muted? No grand declarations about changing the world, just "it's a nice upgrade." The big thing here is they're trying to fix the personality wars—remember when everyone loved 4o because it was friendly, then hated GPT 5 because it was too blunt? Now we've got personality presets: professional, friendly, candid, quirky, efficient, nerdy, and cynical. Pick your poison. They're also claiming better instruction following and "adaptive thinking," though we're still waiting on actual benchmarks. The model's supposedly balancing IQ with EQ, which is a polite way of saying they're trying not to make it a sycophant whilst also not making it mean.

Meanwhile, in news that feels like a Black Mirror episode, a Japanese woman actually married her ChatGPT-generated AI character—ceremony, rings, guests, the lot. It's extreme, obviously, but it highlights the attachment issue OpenAI's trying to navigate with these personality options. Do you give users choice, knowing some will use it for companionship? Their new CMO acknowledges they're working with mental health experts on this, but there's nothing concrete yet.

Also, World Labs released Marble, which lets you generate 3D worlds you can walk around in—think post-apocalyptic London or Rivendell. It's rough now, but this is early-days spatial intelligence stuff that could eventually train AI in simulated environments. Worth playing with whilst it's free.
