Rock Matrix open-sources EdgeRock-4B, a Qwen3.5-4B derivative with reduced memory footprint

By PulseAugur Editorial · [1 sources] ·

Rock Matrix, in collaboration with HKUST and Carnegie Mellon University, has released EdgeRock-4B as an open-source model. This new model is based on Alibaba's Qwen3.5-4B and features sliding-window attention and memory anchors. These innovations significantly reduce the KV cache size to 72 MiB for a 256K context, a 99.1% decrease compared to Qwen's 8 GiB, while maintaining 96.3% of the base model's AIME score. AI

IMPACT This release offers a more memory-efficient LLM, potentially enabling wider deployment on resource-constrained devices.
