Autonomous Agent 'GPT-6 Astra' Beats Portal in Under 24 Hours Without Human Intervention

Developer cozyblaze has published code and documentation detailing an autonomous run where an agent designated 'GPT-6 Astra' beat Valve's puzzle game Portal in roughly 24 hours. After the starting objective was defined, the system solved every chamber without human intervention. While the naming scheme and publication metadata warrant caution, the author framed the result not as a triumph, but as a baseline: it represents the least capable model generation users will likely ever encounter from here on.
