arXiv:2605.15250v2 Announce Type: replace Abstract: Multi-head Latent Attention (MLA), the attention used in DeepSeek-V2/V3, jointly compresses keys and values into a low-rank latent and matches the H100 roofline almost perfectly. Its trained weights, however, expose only one decoding path - an absorbed MQA form - which ties efficient inference to H100-class compute-bandwidth ratios, forfeits tensor parallelism along the head axis, and yields no Multi-Token Prediction (MTP) gain on commodity inference GPUs such as the export-restricted H20. We propose Group-Query Latent Attention (GQLA), a min
The paper addresses current limitations in large language model decoding on commodity hardware, as the industry seeks to optimize AI performance beyond top-tier, export-restricted compute.
Improved attention mechanisms that are hardware-adaptive unlock more efficient and accessible LLM inference, reducing the dependency on specialized hardware like the H100 and potentially democratizing advanced AI capabilities.
The development of Group-Query Latent Attention (GQLA) offers a path to more flexible and efficient LLM decoding, allowing for better performance on a wider range of GPUs, including those subject to export restrictions.

- · Cloud providers with diverse GPU inventories
- · Nations with limited access to leading-edge chips
- · Manufacturers of highly specialized, single-path AI accelerators
- · Users solely reliant on MQA-optimized models for inference
This innovation directly improves the efficiency and adaptability of LLM inference across different hardware, moving beyond H100-specific optimizations.
It could lead to a broader adoption of sophisticated LLMs in regions or organizations that cannot access or afford the most advanced and restricted GPUs.
The development of hardware-agnostic AI components contributes to a more diversified and resilient global AI infrastructure, potentially lessening geopolitical pressures around silicon supply chains.
