AIMPACT states that Nous Research has open-sourced the long-context pretraining mechanism Lighthouse Attention. Processing 512K text on a single B200 card is about 17 times faster; at 98K, the end-to-end speedup is 1.4–1.7 times. This mechanism first performs rough screening and then precise computation: it uses multi-level summaries to filter out the core segments and stitches them into short texts, which are then handled by FlashAttention. The screening logic is outside the kernel, eliminating the need to modify low-level code and additional training objectives. To prevent the model from losing its character-by-character reading ability due to jumping reading, during training it completes most of the process in an accelerated mode, then briefly switches back to full attention at the end. In experiments with 5.3亿 parameters and 500亿 Token, time consumption decreases significantly, and the final performance is comparable to, and even exceeds, traditional baselines.
