Introducing Hotdog-27B, a specialized bipartite classifier. Hotdog-27B beats jev on our independent binary classification benchmark. I expect long term binary classification will have its own set of specialized open models, served on http://classifier.dev. A significant percentage of global tasks are just 0/1 classification. Is there a bug here? Is this a hotdog? Is this document relevant? Is this coding trajectory valuable? The real question is whether by focusing on just binary classification, we can meaningfully improve either accuracy, latency, or throughput. All training code and benchmarks are public to encourage progress in this area: https://huggingface.co/opensporks/hotdog-27B https://github.com/mrmps/tinker-binary#benchmarks
