Frontier lab internal models reportedly lead public releases by 1-3 months

xeophon · x · 2026-09-13

xeophon argues from public reports that the lag between frontier labs' internal models and public releases is roughly 1-3 months, citing the Mythos/Fable lineage: internal access Feb 24, Glasswing April 7 (1.5 months), Fable released June 9 (3.5 months). He also notes Anthropic and OpenAI are both betting on multi-agent systems to scale inference-time compute further.
