潜注意力技术能大幅降低显存占用并提升推理效率,对本地部署和长上下文场景有直接实用价值,建议关注其后续开源进展。

Hello! We've been busy at Telperion with a lot of experimental research (more coming soon). Today, we're announcing the release of our latent attention variants of Qwen3.8-27B.

大家好!Telperion 团队近期忙于大量实验性研究(更多成果即将发布)。今天,我们宣布推出基于 Qwen3.8-27B 的潜在注意力(Latent Attention)变体。

Our latent attention variants (quants calibrated to FP8 KV cache) compress the KV cache by 4×, enabling a near 4× increase in maximum context on consumer hardware or a near 4× increase in concurrency on server hardware. These variants demonstrate great performance, with a statistically distinguishable increase (+6.58%) in SWE performance on our MLA variant, in addition to using upwards of 20% fewer reasoning tokens.

我们的潜在注意力变体(针对 FP8 KV 缓存校准的量化版本)可将 KV 缓存压缩 4 倍,从而在消费级硬件上实现近 4 倍的最大上下文长度提升,或在服务器端硬件上实现近 4 倍的并发能力提升。这些变体展现出卓越的性能:在我们的 MLA 变体中,SWE 性能有统计学意义的提升(+6.58%),同时推理 token 使用量减少了 20% 以上。

Due to the memory downsides of serving MLA on multi-GPU devices, we produced a grouped latent variant using two groups, enabling 4× KV compression for dual GPU users.

由于在多 GPU 设备上部署 MLA 存在内存方面的劣势,我们开发了一种使用两个组的分组潜在变体,为双 GPU 用户实现了 4 倍的 KV 缓存压缩。

We have fantastic recipes for post-training quantization and have produced quantized versions that exceed equivalently sized .gguf quants in fidelity. Our models have an easy to install vLLM plugin.

我们拥有出色的后训练量化方案,并生成了保真度超越同等大小 .gguf 量化版本的量化模型。我们的模型提供了一个易于安装的 vLLM 插件。

The plugin has been verified on RTX PRO 6000s, H100s, and 2× RTX 5060Ti 16GB.

该插件已在 RTX PRO 6000、H100 以及 2× RTX 5060Ti 16GB 设备上验证通过。

We do not believe in gatekeeping ideas or research. As a result we will be open sourcing our method soon. This method requires zero-retraining, and is compatible with almost any model that uses grouped query attention or similar variants.

我们不主张对想法或研究进行封锁。因此,我们将很快开源我们的方法。该方法无需重新训练,且兼容几乎所有使用分组查询注意力(Grouped Query Attention)或其类似变体的模型。

Finally, we plan to make an improved version 2, with a full benchmark suite when we get more compute. We will also be making sparse latent attention variants of Qwen4-27B when released.

最后,当我们获得更多算力时,计划推出改进版的 V2,并附带完整的基准测试套件。此外,在 Qwen4-27B 发布时,我们也将推出其稀疏潜在注意力变体。
