  "summary": "Structured access (API-only deployment) provides meaningful safety benefits through monitoring (80-95% detection rates), intervention capability, and controlled proliferation. Enterprise LLM spend reached \\$8.4B by mid-2025 with Anthropic leading at 32% market share. However, effectiveness depends on maintaining capability gaps with open-weight models, which have collapsed from 17.5 to 0.3 percentage points on MMLU (2023-2025), with frontier capabilities now running on consumer GPUs with only 6-12 month lag.",
  "description": "Structured access provides AI capabilities through controlled APIs rather than releasing model weights, maintaining developer control over deployment and enabling monitoring, intervention.",
