The open-model gap is not one gap

Open weights are roughly four months behind the aggregate frontier. Across coding, agents, reasoning, cost, privacy, and deployment, that average hides the decision that actually matters.

New AI Models May 2026: The Frontier Took a Breath, Architecture Took the Stage

After April broke the ceiling (GPT-5.5 at 60.24, Opus 4.7, DeepSeek V4, Kimi K2.6), May went quiet on scale and loud on architecture. SubQ shipped the first commercial subquadratic LLM with a 12M context. Zyphra dropped an 8B MoE trained on AMD. OpenAI made GPT-5.5 Instant the new ChatGPT default.

The world is built out of a few narrow places

A long letter on why I built AI Bottlenecks. EUV machines, indium phosphide wafers, CoWoS slots, gas turbines, and the four physical chokepoints gating the 2026 to 2030 AI buildout. The constraint is never at the loud end of the stack.
