“AI in 2025: gestalt” by technicalities

Author: LessWrong December 8, 2025 Duration: 41:59
This is the editorial for this year's "Shallow Review of AI Safety". (It got long enough to stand alone.)

Epistemic status: subjective impressions plus one new graph plus 300 links.

Huge thanks to Jaeho Lee, Jaime Sevilla, and Lexin Zhou for running lots of tests pro bono and so greatly improving the main analysis.

tl;dr

  • Informed people disagree about the prospects for LLM AGI – or even just what exactly was achieved this year. But they at least agree that we’re 2-20 years off (if you allow for other paradigms arising). In this piece I stick to arguments rather than reporting who thinks what.
  • My view: compared to last year, AI is much more impressive but not much more useful. They improved on many things they were explicitly optimised for (coding, vision, OCR, benchmarks), and did not hugely improve on everything else. Progress is thus (still!) consistent with current frontier training bringing more things in-distribution rather than generalising very far.
  • Pretraining (GPT-4.5, Grok 4, but also counterfactual large runs which weren’t done) disappointed people this year. It's probably not because it wouldn’t work; it was just ~30 times more efficient to do post-training instead, on the margin. This should [...]

Dive into a stream of ideas where technology, culture, philosophy, and society intersect, all through the lens of the LessWrong (Curated & Popular) podcast. This isn't a traditional talk show with hosts, but rather a curated audio library of the most impactful writing from the LessWrong community. Each episode is a narration of a full post, selected for its high value and interesting arguments, focusing on pieces that have been formally curated or have garnered significant community approval. You'll hear clear, thoughtful readings of essays that tackle complex topics like artificial intelligence, rational thinking, moral philosophy, and the forces shaping our future. The audio format lets you absorb these dense, often paradigm-shifting concepts during a commute or a walk, turning written analysis into an immersive listening experience. This particular feed is deliberately selective, offering a manageable stream of the community's standout work. For those who want an even deeper dive into the discussion, there are broader feeds available.

TL;DR We describe the persona selection model (PSM): the idea that LLMs learn to simulate diverse characters during pre-training, and post-training elicits and refines a particular such Assistant persona. Interactions wi…
