RECENT DEVELOPMENTS IN LLM ARCHITECTURES: KV SHARING, MHC, AND COMPRESSED ATTENTION

KV-cache size, memory traffic, and attention cost quickly become the main constraints as reasoning models and agent workflows keep more tokens around for longer. LLM developers are adding a growing number of architecture tricks to reduce costs. Most of the changes look like small tweaks, but some are quite intricate design changes. This article looks at these architecture changes with a focus on what changes inside the transformer block, residual stream, KV cache, and attention computation.

LIGHTHOUSE ATTENTION

Lighthouse Attention, a selection-based hierarchical attention, offers up to 17x faster forward and backward passes than standard attention models at large contexts. It utilizes FlashAttention on a dense sub-sequence, maintaining efficiency and compatibility with upstream improvements. By enabling efficient long-context training and retaining dense model competence, Lighthouse Attention achieves 1.4x to 1.7x speedup in pretraining while reducing computational costs.

RUNWAY STARTED BY HELPING FILMMAKERS — NOW IT WANTS TO BEAT GOOGLE AT AI

Runway's founders believe that the next form of AI will be built from video and world models that learn how the world works. The company is training models directly on observational data to reach the next frontier of AI. Runway was one of the first to develop AI video generation, but world models are a different race with deep-pocketed competitors. The company has raised $860 million to date, but it is going against incumbents like OpenAI and Google.

THE HAVES AND HAVE NOTS OF THE AI GOLD RUSH

The AI boom has created a wealth divide, with an estimated 10,000 individuals from companies like OpenAI and Nvidia achieving over $20M in wealth, while others face uncertain futures with stagnant job prospects and layoffs. Software engineers express concerns about their skills becoming obsolete, raising anxiety about career paths. This disparity fuels tension in San Francisco's tech scene as some criticize the dual role of AI as a wealth source and a career threat.
