Open-Weight Frontier Release
open_weight_release · AI-governance topic
Open-Weight Frontier Release is governance posture toward releasing frontier model weights publicly (Meta Llama, Mistral, DeepSeek vs. closed-weight Anthropic / OpenAI / DeepMind). EU AIA Recital 102 + Art. 53(2) carve-outs; CA SB-1047's failed framework; Meta Frontier AI Framework's explicit defence; emerging US export-control overlay. Across 26 tracked AI-governance instruments, 3 address this topic explicitly, 7 via general principles, and 16 are silent.
Definition and scope
Governance posture toward releasing frontier model weights publicly (Meta Llama, Mistral, DeepSeek vs. closed-weight Anthropic / OpenAI / DeepMind). EU AIA Recital 102 + Art. 53(2) carve-outs; CA SB-1047's failed framework; Meta Frontier AI Framework's explicit defence; emerging US export-control overlay.
The cross-jurisdiction picture below shows how each of 26 tracked instruments treats this topic. The patterns vary substantially — and 16 regimes are silent, leaving gaps that future policy work could address.
Historical primacy & cross-jurisdiction tension
First addressed by Interim Measures for Generative AI Service Management on (implicit). Subsequent regimes have either codified, diverged from, or remained silent on this baseline.
