Tencent Hy4 is being prepped for launch 👀 A new vLLM-Ascend PR adds a deployment guide for the final Hy4, not the Preview: the same 770B MoE with 49B active, with image input and a 10B native MTP layer. Its weights and Docker image aren't public yet. https://github.com/vllm-project/vllm-ascend/pull/20671
