Tencent. Released 5 October 2026.
This model accepts text and pictures as input and produces text as output. It can process up to 1000 pages of material at one time and generate responses up to 65 pages long. It is designed for complex, real-world productivity tasks that require planning and the use of specific tools. However, it cannot access the internet to find new information.
Hy4 preview reads and writes text, and keeps about 1,000 pages in mind at once. Tencent built it for coding assistants, long jobs that use the tools and apps you connect to it, and office-style work that needs planning and a steady thread over many steps. Pick it when the material is very long.
Hy3 reads and writes text, and keeps about 260 pages in mind at once. You choose how hard it thinks: not at all by default, or at a low or high level for tricky maths, coding and problems with many steps. Tencent points it at coding, game development, financial analysis, document work and web page design, and says it flags missing evidence rather than inventing an answer. Hy4 preview reads about 1,000 pages at once.
Hy3 preview reads and writes text, and keeps about 260 pages in mind at once. You can switch its thinking off, or set it to low or high, trading speed for depth depending on the job. Tencent builds it for long jobs with many steps and for writing code. As a preview it is for trying this line before settling on the finished Hy3, which has the same reading size.
