I built a new attention mechanism (wave field) — runs 128K context where standard attention OOMs, 80+ tok/s on laptop CPU
Summary
A solo researcher introduces Wave Field attention, replacing standard O(N²) dot-product attention with FFT wave convolution, achieving O(N log N) training and O(1) inference per token. Claimed 80+ tok/s on CPU with 128K context and better zero-shot performance than GPT-2 124M.

Wall Attention generalizes diagonal forget gates to softmax attention, enabling state-of-the-art length extrapolation from 4k to 160k+ context zero-shot and outperforming RoPE and FoX in pretraining. It is released as a drop-in replacement with open-source Triton kernels.
Wall Attention (GitHub Repo)
Wall Attention is a new attention variant with per-channel, per-timestep multiplicative decay, providing content-dependent forgetting rates and efficient training/decode kernels implemented in Triton.
I released a softmax-free attention model at GPT-2 Medium scale (~354M params, 11.5B tokens): structural sparsity + tile-skipping kernels for long-context VRAM savings. Open weights + custom Triton kernels [R]
Released RRT-355M, a softmax-free attention model at GPT-2 Medium scale with 354M parameters trained from scratch on 11.5B tokens, using structural sparsity and tile-skipping kernels for long-context efficiency, achieving comparable performance to GPT-2 Medium on a 22-task benchmark.

MiniCPM-SALA is a 9B-parameter hybrid attention model that interleaves sparse and linear attention to overcome the quadratic compute and large KV cache bottlenecks of long-context Transformers. It achieves 3.5x faster inference than Qwen3-8B at 256K tokens and supports up to 1M tokens on consumer GPUs, with a cost-effective continual training approach that reduces training costs by ~75%.
