What Hacker News says
2 sourcesStrangers pretrained a language model with HF PRs and a cron job
Last week a few of us pretrained a 15M-parameter language model from scratch —
past its Chinchilla-optimal token budget — with no cluster, no server, and no
budget. The training coordinator is a GitHub Actions cron job. The gradients
are pull requests. By the end, someone we'd never met had joined and trained
23M tokens of it.
