arXiv Endorsement Requirements for AI

In late March, a first-time submitter appeared on LocalLLaMA asking for an arXiv endorsement in cs.AI — the gatekeeping step that prevents the preprint server from being flooded with unreviewed work from unknown authors. The post was modest, almost apologetic in tone, the kind of quiet plea that gets buried in a weekend scroll. Then, three weeks later in mid-April, a second researcher surfaced with a near-identical request, this time specifically for a paper on TensionLM, described as a new attention mechanism. Two posts, twenty days apart, both indie researchers, both stuck at the same door.

If confirmed as a genuine pattern, here is what this means. The endorsement system — designed to protect arXiv's signal-to-noise ratio — is quietly functioning as an invisible barrier to independent AI research at precisely the moment when the number of capable people working outside institutions is rising fastest. Someone can train a model, develop a novel architecture, write a coherent paper, and still be blocked from the primary venue where the field takes ideas seriously, simply because they don't know the right person. The second-order effect is subtler but more corrosive: it pushes independent researchers toward unreviewed platforms or social media for distribution, which fragments the research record and makes genuinely interesting work harder to find. For a field already struggling with reproducibility and credit attribution, that's a problem with a long tail.

Watch for whether the TensionLM paper eventually finds an endorser and surfaces on arXiv — and whether any coordinated response emerges from the research community to route independent submissions through a more accessible endorsement network.
