arco consistently outperforms every sota model below 600m parameters as well as some 1b base models on average on 5 core benchmarks and is competitive with the best 0.7b-1b llms. arco is a merge of multiple internal models fine-tuned on a diverse set of styles and finally merged with the several models (including palmer-004-turbo and danube3-chat), followed by a merge with base model to preserve knowledge.
