Overview
The official release of Hy4 delivers comprehensive and substantial improvements over Hy4 Preview, with particularly strong gains in agentic capabilities and performance across a wide range of long-horizon, real-world productivity...
Our take
For users needing to process extensive documents or conversations, Tencent: Hy4 offers a substantial 1,048,576-token context window, exceeding many comparable models. This makes it suitable for research or writing tasks that involve very long inputs. Unlike general-purpose chatbots such as ChatGPT or Claude, which may focus on conversational fluency, Hy4 emphasises agentic capabilities through built-in reasoning and support for tool/function calling. This allows it to handle more complex, multi-step workflows, including generating structured JSON outputs. Its vision capability also enables image input, expanding its utility beyond text-only models. Ideal for developers or enterprises building automated systems that require processing large amounts of data and executing defined actions, particularly those needing robust reasoning and structured responses. However, with no free tier and usage billed per token, it is less suited for casual or infrequent individual use.
