About
Kimi K2 Thinking is an advanced open source reasoning model developed by Moonshot AI, designed specifically for long-horizon, multi-step workflows where the system interleaves chain-of-thought processes with tool invocation across hundreds of sequential tasks. The model uses a mixture-of-experts architecture with a total of 1 trillion parameters, yet only about 32 billion parameters are activated per inference pass, optimizing efficiency while maintaining vast capacity. It supports a context window of up to 256,000 tokens, enabling the handling of extremely long inputs and reasoning chains without losing coherence. Native INT4 quantization is built in, which reduces inference latency and memory usage without performance degradation. Kimi K2 Thinking is explicitly built for agentic workflows; it can autonomously call external tools, manage sequential logic steps (up to and typically between 200-300 tool calls in a single chain), and maintain consistent reasoning.

About
Mercury 3 is a hosted generative AI model from Inception for developers building interactive applications. It uses a diffusion-based approach to generate text in parallel and supports streaming responses, tool use, structured outputs, and multimodal input including text, images, and audio. Through the Inception API, teams can use it for conversational assistants, voice applications, search and browsing workflows, tutoring, and other agentic tasks that benefit from responsive generation. The model is available through Inception’s API and named inference partners, with OpenAI-compatible API access for existing applications. Developers can evaluate output quality and latency, then integrate the model into their software using the documented API and SDK ecosystem. Usage is token-metered, with a free allocation and paid input/output token rates; enterprise options include dedicated capacity and support.
