Lumina predicts Hy4 will leave preview this week or next

Hy4 could leave preview this week or next, according to @LuminaBench. In a 3 November post, the account points to what it describes as a vLLM pull-request screenshot and predicts a substantial improvement over the preview. That timing and the expected quality jump are the author's forecast.

Tencent already released and open-sourced Hy4 preview on 28 August. Its published repository describes a model aimed at coding and other productivity work. The development to watch is therefore a possible successor to that preview: would developers get a meaningfully stronger model to run or connect to their existing tools?

The cropped image in Lumina's post contains the model name “hy4”, but it does not show a pull-request number, filename or commit. We could not match that crop to its original code change. vLLM's official deployment recipe already supports Hy4 preview, so the short name alone does not establish that new weights or a finished release are available.

The useful next evidence would be a Tencent release note or model card identifying the new version, its availability and results against the preview under comparable conditions. For now, the post gives a specific release-window rumor worth tracking; it does not provide a verified launch date or performance measurement.
