Tencent / Hy4 Preview
proDescription
Hy4 Preview is an early release of Tencent's next Hy model, the successor to Hy3. Tencent built it for real productivity work like software engineering, office tasks, data analysis, and scientific research, and released it as an open model.
Chat with it for long coding tasks, front-end work, financial and data analysis, and drafting documents and spreadsheet content. It works with text, holds a very large amount of context, and thinks problems through before it answers.
As a preview, it can spend extra time checking its own work, and Tencent is still refining it. For a quick, free option from the same family, Hy3 is on Aymo's free plan.
