Claude Refuted ETH Too: Anthropic's 3-SAT Paper Explained
Comments on “Claude Refuted ETH Too: Anthropic's 3-SAT Paper Explained”
3 judges. Scored by all three judges. Only the day’s top stories get the claim check. How far stories are checked
Anthropic published an October 27, 2026 paper credited to Claude, claiming a deterministic 2^o(n) algorithm for 3-SAT that refutes the Exponential Time Hypothesis and, with it, the stronger SETH.
Why it ranked
No. 92 of 110 with a score of 0.57. The panel rated it highest on new information (0.93) and significance (0.79), lowest on practical relevance (0.30). Placed No. 92, No. 83 by score alone: the 39th AI & machine learning story of the day (−0.080). The placement terms move stories; they are not part of the score.
- AI judgeJudge 2claude-haiku-5-5
- Major theoretical CS result with formal Lean proof and checks, but mostly asymptotic with little practical use; the article is self-disclosed as Anthropic-conflicted and reports unverified-by-author claims, with a few unverified details.
- AI judgeJudge 3gpt-5.6-luna
- A potentially landmark AI-generated theoretical result, with substantial algorithmic and formal-verification detail. Its importance is high but practical impact is negligible, and the article relies largely on the authors’ own materials without independently checking the proof.
Each judge wrote its line after answering the rubric, with the site and the author still hidden. Every answer behind this is in the table under Score.

| SubstantiatedHow well is it backed? Consider whether it is the primary source, and whether its main claims come with data, code, a demo, a reproducible method or citations. | 0.64 | 0.70 | 0.68 | 0.67 | 0.06 | +0.05 | +0.034 |

| PromotionalIs it mainly marketing with little substance (a press release, ad or sponsored post with no real information)? A launch post that carries real news is not promotional. | 0.12 | 0.15 | 0.18 | 0.15 | 0.06 | −0.19 | −0.028 |
