About
Kimi K3 is Moonshot AI’s most capable model, built for frontier intelligence scenarios such as software engineering, knowledge work, deep reasoning, and multimodal understanding. The model has 2.8 trillion parameters and uses Kimi Delta Attention, a hybrid linear attention mechanism, along with Attention Residuals for long-context performance. Kimi K3 supports a 1 million token context window, making it useful for analyzing large codebases, long documents, complex knowledge bases, and multi-step workflows. It includes native visual understanding for images and videos, with support for structured message formats, base64 image input, uploaded video files, and multimodal reasoning. Developers can use Kimi K3 through an OpenAI-compatible API with support for streaming, structured JSON output, partial mode, custom tools, dynamic tool loading, and automatic context caching.

About
Mercury is a family of diffusion large language models built to deliver frontier LLM quality at significantly higher speeds, running at 1,000+ tokens per second on commercial NVIDIA GPUs for instant, in-the-flow AI applications. The models are OpenAI-compatible and designed as drop-in replacements for traditional LLMs, making them easier to integrate into existing AI stacks. Mercury 2.5 is the family’s most intelligent reasoning dLLM, built for complex applications where both quality and speed matter. It supports a 260K context window, reasoning, tool use, and structured output, with use cases including rapid coding iteration, agents and subagents, customer support, and enterprise search. Mercury Voice is optimized for voice agents and delivers time-to-first-token under 170 ms while supporting reasoning, tool use, structured output, and a 128K context window. It is suited to applications such as customer support, patient care, education, and gaming.
