Liquid AI’s New LFM2-24B-A2B Hybrid Architecture Blends Attention with Convolutions to Solve the Scaling Bottlenecks of Modern LLMs
The generative AI race has long been a game of ‘bigger is better.’ But as the industry hits the limits of power consumption and memory bottlenecks, the conversation is shifting from raw parameter counts to architectural efficiency. Liquid AI team is leading this charge with the release of LFM2-24B-A2B , a 24-billion parameter model that redefines what we should expect from edge-capable AI. https://ift.tt/C3VNmOc The ‘A2B’ Architecture: A 1:3 Ratio for Efficiency The ‘A2B’ in the model’s name stands for Attention-to-Base . In a traditional Transformer, every layer uses Softmax Attention, which scales quadratically (O(N 2 )) with sequence length. This leads to massive KV (Key-Value) caches that devour VRAM. Liquid AI team bypasses this by using a hybrid structure. The ‘Base ‘ layers are efficient gated short convolution blocks , while the ‘Attention ‘ layers utilize Grouped Query Attention (GQA) . In the LFM2-24B-A2B configuration, the model uses a 1:3 ratio: Total Layers: 40...
