Linkup has released SPARSEUP, its first model and the missing sparse companion to DenseOn and LateOn. Same backbone and data, under 150M parameters, it scores 56+ on BEIR-13. The model is open-sourced under Apache 2.0, with blog post and weights available. Commenters are optimistic about combining sparse representations with late interaction.
