Description

Mercury represents an advanced family of diffusion large language models engineered to achieve top-tier LLM performance at remarkably fast speeds, processing over 1,000 tokens per second on commercial NVIDIA GPUs for immediate AI applications. These models are compatible with OpenAI and are designed to seamlessly replace traditional LLMs, facilitating easier integration into current AI frameworks. Among them, Mercury 2.5 stands out as the most sophisticated reasoning diffusion LLM, tailored for intricate applications where both performance and quality are priorities. It boasts a substantial 260K context window, enabling advanced reasoning, tool utilization, and structured output, with practical applications ranging from swift coding cycles to the development of agents, customer support solutions, and enterprise-level search functionalities. Additionally, Mercury Voice is specifically fine-tuned for voice agents, achieving a remarkable time-to-first-token of under 170 ms and supporting reasoning, tool use, structured output, and a 128K context window. This makes it highly suitable for various applications, including customer support, patient care, educational tools, and gaming experiences. Overall, the Mercury family is focused on pushing the boundaries of what AI can accomplish in real-time environments.

Description

Step 3.5 Flash is a cutting-edge open-source foundational language model designed for advanced reasoning and agent-like capabilities, optimized for efficiency; it utilizes a sparse Mixture of Experts (MoE) architecture that activates only approximately 11 billion of its nearly 196 billion parameters per token, ensuring high-density intelligence and quick responsiveness. The model features a 3-way Multi-Token Prediction (MTP-3) mechanism that allows it to generate hundreds of tokens per second, facilitating complex multi-step reasoning and task execution while efficiently managing long contexts through a hybrid sliding window attention method that minimizes computational demands across extensive datasets or codebases. Its performance on reasoning, coding, and agentic tasks is formidable, often matching or surpassing that of much larger proprietary models, and it incorporates a scalable reinforcement learning system that enables continuous self-enhancement. Moreover, this innovative approach positions Step 3.5 Flash as a significant player in the field of AI language models, showcasing its potential to revolutionize various applications.
