A repository promoted by Jacky Kwok reports a test-time scaling method in which DeepSeek V4 Flash generates five coding-agent trajectories and then ranks them using the same model as an LLM verifier. The cited post says this self-verification step raised Terminal-Bench 2.1 accuracy from 79% to 88%, surpassing Claude Fable 5 at roughly one-eleventh the cost. The supplied snippets do not establish who developed the method or provide an independent reproduction, and other results cite different V4 Flash scores and evaluation setups, so the performance and cost comparison remains provisional.
The released method operationalises Scott’s inference-time scaling and generate-and-judge positions, while its use of the same model to produce and rank trajectories directly pressure-tests his claim that reliable verification must fail differently from generation. A reproducible 88% result at the reported cost would materially affect his coding-agent orchestration and model-barbell economics; the existing DeepSeek V4 Flash radar case tracks the related base-model benchmark dispute, not this five-trajectory self-ranking result.

After several days, no independent benchmark run, methodological audit, or cost validation has emerged; repeated engagement updates only amplify the original artifact. The episode has faded and can be reopened if an external reproduction appears.

The refreshed comments remain speculative amplification of the same repository result, with no independent benchmark reproduction, verifier-failure analysis, or cost audit. The claim remains economically consequential but provisional.

Refreshed discussion adds only speculative analogy and enthusiasm, not an independent benchmark run, verifier-failure analysis, or cost audit. The economically consequential result remains a testable but single-artifact claim awaiting reproduction.

The HN attachment only redistributes the already-known repository claim and adds no independent benchmark run, methodological audit, or cost validation. The method remains testable and relevant, but its reported advantage is still provisional.

evidence attached: hn.story.49348195 — The linked GitHub artifact is direct first-party evidence for the existing DeepSeek V4 Flash self-verification claim.

No independent reproduction or new methodological evidence has appeared; the only change is modest engagement around the already-known artifact. The self-verification and cost claims therefore remain provisional, and the case can cool while awaiting an external benchmark run.
