Moore Threads announced that its flagship MTT S5000 GPU has successfully completed full adaptation for Alibaba's three newly open-sourced Qwen3.5 models, leveraging native MUSA C support and Triton-MUSA compatibility to deliver high-performance inference.

IT Home reported on February 26, 2026, that following the open-sourcing of the Qwen3.5-397B-A17B, Alibaba has announced the release of three new medium-scale models: Qwen3.5-35B-A3B, Qwen3.5-122B-A10B, and Qwen3.5-27B (Dense). In response, Moore Threads officially announced that it has immediately completed comprehensive adaptation for these three new models on its flagship AI training and inference all-functional GPU, the MTT S5000.

Moore Threads stated that the adaptation process for the Qwen3.5 series validated two core capabilities of the MUSA ecosystem designed to empower developers:

  • Native MUSA C Support: Allows developers to use MUSA C directly for kernel development, significantly lowering the barrier for migration from the CUDA ecosystem.
  • Deep Compatibility with Triton-MUSA: Developers can use familiar Triton syntax to write high-performance operators, which run seamlessly on Moore Threads' full-function GPUs via the Triton-MUSA backend.

At the underlying technical level, Moore Threads achieved native optimization for the hybrid attention mechanism adopted by the Qwen3.5 multimodal models. Leveraging the muDNN computing library and the MATE open-source operator library, Moore Threads provided efficient support for long-sequence processing within the hybrid attention mechanism, successfully realizing high-performance inference of the model on the MTT S5000.

The models are currently available for download on GitHub, Hugging Face, and the ModelScope community for research and fine-tuning.

This is a significant step for China's domestic AI hardware ecosystem. Moore Threads' full adaptation of Alibaba's powerful Qwen3.5 models on the MTT S5000 demonstrates tangible progress in building a sovereign, high-performance software and hardware stack. The use of native MUSA C and Triton compatibility shows a commitment to creating a viable alternative development environment, not just a single chip. For the broader open-source community, it means more accessible, locally-optimized pathways to run state-of-the-art models. This collaboration between a leading AI software house and a domestic GPU designer is exactly the type of synergy needed to reduce external dependencies and foster genuine innovation within the ecosystem.

This is a significant step forward for China's domestic AI computing ecosystem. Seeing Moore Threads' MTT S5000 achieve full adaptation with Alibaba's latest Qwen models demonstrates real, practical synergy between key hardware and software players. It moves beyond theoretical compatibility into deliverable high-performance inference, which is crucial for real-world adoption. The focus on native MUSA C support and Triton-MUSA compatibility shows they are building a serious, developer-friendly stack, not just a prototype. This kind of deep collaboration is exactly what's needed to build a resilient and competitive alternative to the current dominant tech stacks.
