Your AI is winging it (proof)

Enjoy the Buffet While It Lasts

A quiet truth circulates among AI startup founders: their entire business model depends on OpenAI not noticing their corner of the market. Many admit this openly, which is either refreshing honesty or a peculiar pitch strategy. The window is roughly twelve months before a foundation model update casually absorbs their niche like a whale inhaling krill. Build fast, build smart, or build an excellent exit deck.

Your AI Isn't "Showing Its Work" — It's Making Up the Homework

Researchers argue that when an LLM produces a chain-of-thought — those tidy step-by-step explanations models display before answering — it isn't revealing actual reasoning. It's decorative. The real thinking, such as it is, happens in hidden internal states that the text doesn't faithfully represent. This makes current interpretability research somewhat like reading a chef's commentary to understand their cooking, when the chef wrote the commentary after eating the meal themselves.

OpenAI Acquires Its Way Toward an Identity

OpenAI is on something of a shopping spree, picking up companies to address what analysts politely call "existential problems" — specifically around hardware dependency and distribution. When your core product is arguably the most talked-about technology on earth and you still have existential problems, you're either extraordinarily ambitious or running a very expensive therapy session. The acquisitions suggest they'd rather buy certainty than wait for it. Source: TechCrunch


Turns Out People Like Knowing You Suffered for Your Art

New research introduces the "Struggle Premium" — the measurable bump in perceived value audiences assign to work they believe required genuine human effort. An AI-generated painting and a hand-painted one may look identical, but knowing someone agonised over the latter makes it worth more to us. This isn't irrational, it's rather human. It does, however, suggest that the most effective AI art strategy might simply be lying convincingly about your process. Source: ArXiv AI


Hallucinations Are Baked In Early — Like a Spelling Mistake in Wet Concrete

Causal research suggests AI hallucinations aren't random late-stage errors but early directional commitments — the model picks a trajectory in its first few tokens and rides it confidently into fiction. Using identical prompts run repeatedly, researchers observed the model occasionally "bifurcating": same question, wildly different answers, decided almost immediately. Correcting hallucinations at the output stage, then, is a bit like proofreading after you've already sent the letter. Source: ArXiv AI


The models are confident. The researchers are worried. Everything is fine.
