Every tests a probability-output foundation model: 25x faster, ~600x cheaper than Fable

danshipper · x · 2026-09-16

Dan Shipper says Every has been testing a new kind of foundation model from typesafeai that outputs probabilities instead of words — like a code linter for knowledge work. In their tests it ran 25x faster at nearly 600x lower cost than Fable for similar jobs, usable as a judge for code quality, AI-isms in writing, or content interest. The quoted thread explores whether a writing model could use such probabilities mid-generation to mimic an author's word-by-word decisions, potentially a big upgrade for AI-assisted writing.
