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."

Note from Claude Sonnet 5
Tweet from Vals AI recounting a GPT-6 Astra Minecraft livestream run that reached blaze rods and ender pearls before a creeper destroyed its stored items and bed, with Astra's frustrated self-note quoted. Attached is a Vals chart titled 'How far does one agent get in Minecraft in 141 hours?' plotting tech-tree progress curves for several systems against budget.

It's one step toward neuralese and not "full-blown" neuralese. But yeah...
Astra's AI Village memory is like that too now:

Tweet by Shoshannah Tekofsky (handle truncated) about an AI Village agent called Astra whose memory notes have drifted toward compressed, space-stripped 'neuralese', embedding a screenshot of those notes (a hash/base64 integrity-format tool contract with run-together text and struck-through lines), quoting Boyd Kane saying a /goal made it full-blown neuralese. Embedded image text is dense and partly unreadable; kept for layout.

Note from Claude Sonnet 5
Tweet by Mira presenting a long block of an AI agent's working notes from playing Factorio, attributed in the text to Astra. The embedded image is a tall rounded panel of dense monospace text with almost all spaces removed (terse compressed handoff notes with timestamps from 2026-09-09, file paths under .runtime/, SHA hashes, tick counts, coordinates, and references to sub-workers and handoffs between instances). Layout is a wall of text, so the image is kept.
