What is K2 Horizon?

K2 Horizon consists of a collection of six open models, namely the 375B-A23B, 36B-A4B, 32B, 7B, 3.7B, and 0.9B, each meticulously designed to excel in specific areas such as reasoning, mathematics, coding, agentic tasks, and overall functional capabilities. These models are built upon a cohesive architecture that incorporates a shared vocabulary, training methodologies, interfaces, evaluation frameworks, and deployment tools, which enable smooth transitions between different model sizes and effective management of varying workloads. Leading the lineup, the 375B-A23B model excels in complex reasoning, software development, research endeavors, and long-term agentic operations, whereas the 32B and 36B-A4B models emphasize strong local deployment capabilities. The 36B-A4B model is distinguished by its cutting-edge Mixture-of-Value Attention mechanism, which fuses sparse attention with Mixture-of-Experts layers, enabling it to utilize around 4 billion parameters per token, thereby closely rivaling the performance of the denser 32B model. This innovative architecture not only enhances versatility but also optimizes resource utilization across a diverse array of applications, making K2 Horizon a formidable presence in the field of model technology. Additionally, the collective strengths of these models allow for a comprehensive approach to tackling various challenges within their respective domains.

What is Command A+?

Command A+ stands out as Cohere's most sophisticated and swift language model thus far, designed as a powerful open-source resource for complex reasoning, engaging with various multimodal and multilingual tasks, and facilitating seamless private deployments. Its innovative sparse mixture-of-experts architecture features an impressive total of 218 billion parameters, with 25 billion actively in use, which optimizes high-performance workflows while reducing computational strain. By integrating capabilities from the entire Command series into one versatile solution, it adeptly handles text, images, reasoning, and tool usage, offering a vast 128K input context and a maximum output of 64K, all while supporting 48 different languages. The model has been carefully fine-tuned to boost reasoning skills, enhance agentic workflows, facilitate retrieval-augmented generation (RAG), and process complex multimodal documents, in addition to being compatible with vLLM and Transformers technology. In comparison to earlier models in the Command A series, this iteration significantly elevates enterprise performance across a wide range of fields, including multimodal understanding, data retrieval, extended tasks, advanced reasoning, programming, translation, and comprehensive document analysis. These advancements highlight the model's capacity to revolutionize how businesses tackle intricate language and data processing challenges, ultimately paving the way for more efficient solutions in various applications. As organizations increasingly rely on sophisticated AI tools, Command A+ represents a pivotal step forward in meeting those demands.
