About

Hy3 preview is Tencent Hy’s most intelligent model in the Hy series to date, built as a 295B-parameter Mixture-of-Experts model with 21B activated parameters, 3.8B MTP layer parameters, and support for up to a 256K token context window. As the first model trained on Tencent Hy’s rebuilt infrastructure, Hy3 preview is designed to improve real-world usability across complex reasoning, instruction following, context learning, coding, agent capabilities, and overall inference performance. It integrates both fast and slow thinking capabilities, allowing direct responses for simpler tasks and deeper reasoning for complex math, coding, and reasoning work. The model is built around well-rounded capabilities across long-context understanding, instruction following, tool use, and agent workflows, with evaluation focused not only on standard benchmarks but also on authentic business and development scenarios.

About

Nex-N2-mini is an open source agentic model with Agentic Thinking, built for real-world productivity scenarios where fast instruction following, real-time tool execution, and cost-effective large-scale deployment matter. As part of the Nex-N2 family, it is designed to turn thinking into actions that are executable, verifiable, and iterable, rather than treating reasoning, tool use, and environment execution as separate capabilities. Nex-N2-mini uses the same unified Agentic Thinking framework as Nex-N2-Pro, connecting requirement understanding, task planning, code implementation, environmental feedback, evaluation, debugging, and continuous iteration into one closed loop. Its thinking paradigm stays consistent across search, coding, and agentic tool calling, following goal decomposition, state tracking, strategy adjustment, and self-verification, which is especially useful in mixed tasks where coding is interleaved with searches and tool calls.
