Poolside has released a new coding model, Laguna S 2.1, which has demonstrated impressive performance despite its relatively small size. Unlike larger models, Laguna S 2.1 was trained to continuously evaluate and revise its work, as well as avoid giving up during long tasks. As a result, it has outperformed several larger rivals in benchmark tests. Additionally, the model has successfully solved a long-standing math problem that had been unsolved since 1975. This achievement highlights the potential for smaller models to be just as effective as their larger counterparts in certain tasks.
