Description
Kimi K3 is a large-scale AI model from Moonshot AI designed for advanced reasoning, software engineering, visual understanding, agentic workflows, and knowledge work. The model is built with 2.8 trillion parameters and uses Kimi Delta Attention, a hybrid linear attention design created to support long-context intelligence. It also includes Attention Residuals and a native 1 million token context window, giving developers room to work with large files, repositories, documentation sets, transcripts, and enterprise knowledge bases. Kimi K3 always runs with thinking mode enabled and currently supports maximum reasoning effort by default. Developers can access the model through Moonshot’s OpenAI-compatible API using Python, cURL, and the OpenAI SDK. The API supports standard chat completions, streaming output, structured JSON Schema responses, partial continuation from a prefix, custom tool calling, required tool choice, and dynamic tool loading. Kimi K3 also supports vision inputs, including local images encoded as base64 and video files uploaded through the file API. Automatic context caching helps repeated long-prefix workflows become more efficient without requiring manual cache IDs or extra cache parameters. By combining long context, visual understanding, tool use, structured output, and advanced reasoning, Kimi K3 is built for developers creating sophisticated AI agents, coding systems, research tools, and enterprise applications.
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.
