3 judges. Scored by all three judges. Only the day’s top stories get the claim check. How far stories are checked

A solo replication on Qwen3-1.7B with OpenThoughts data tested LoRA-specific optimizers against AdamW and Muon at ranks 16 to 256, using one seed. Anpaure's reverse-engineered Dimuon variant led at every rank, with the margin growing with rank.

Why it ranked

No. 65 of 107 with a score of 0.60. The panel rated it highest on new information (0.92) and technical depth (0.92), lowest on audience breadth (0.43). Placed No. 65, No. 55 by score alone: the 26th 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
Detailed, reproducible ablation study of LoRA-specific optimizers versus Muon and AdamW; strong technical depth and practical lr guidance, but narrow audience of ML practitioners.
AI judgeJudge 3gpt-5.6-luna
A technically detailed, reproducible optimizer ablation study for LoRA, with concrete setup, results, uncertainty caveats, and implementation guidance. It is highly relevant to AI practitioners, though single-seed and limited-scope experiments constrain significance.

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.
