Nathan Lambert's Interconnects newsletter documents a structural shift in the open AI model ecosystem: no longer dominated by a few Chinese labs, it now features sovereign AI players, product companies, and Western frontier startups like Zyphra and Poolside with distinct release motivations.

The open AI model landscape has diversified significantly beyond the Llama-era dynamic. Interconnects' Florian Brand and Nathan Lambert identify three distinct categories of open model makers now active globally. 'Pure' model makers — Poolside, Arcee, Zyphra, DeepSeek, and sovereign players like Cohere, Mistral, and Trillion Labs — aim for frontier or near-frontier capability as their primary goal. Big Tech players such as Alibaba (Qwen), Google (Gemma), and NVIDIA open-source for ecosystem reasons: Alibaba to upsell closed models, NVIDIA to drive GPU demand. Product companies like JetBrains, Zed, and Photoroom release specialized small models to reduce dependency on closed API providers without threatening their core business. The newsletter specifically highlights Zyphra, Cohere, and Poolside as representative examples of this diversity. The authors note the Mythos 5 incident has heightened policymaker interest in sovereign model training, potentially accelerating nationally-motivated open model development across Europe and beyond. The broader thesis: the era of open models being driven by a single actor type is ending, replaced by a long tail of specialized releases. The authors argue that restricting this ecosystem is both futile and counterproductive — concentrating AI development among the few while blocking the many.
