Vals AI (verified) @ValsAI · 5h GPT-6 Astra had gotten further than any AI system had ever gone in Minecraft. It was able to set up a semi-automatic blaze farm, allowing it to collect 6 blaze rods. It then located a warped forest, where it killed 6+ endermen and collected 3 pearls. As thousands of viewers watched the stream, Astra put all of its valuable items in a chest. Then a creeper showed up and blew up both the chest and Astra's bed, wiping out all of its progress. Astra seemed to get extremely frustrated after this happened. Astra said to itself, "ALWAYS CARRY CRITICALITEMS withkeepInventory; don'tstoreinunguardedchesteveragain."
