Did you know Elon Musk was weirdly "predicted" in a Wernher von Braun book nearly 80 years ago? In his 1948 novel *Project Mars*, von Braun describes a future Martian government led by a figure called the "Elon." It's not a person's name, but a title for the head of government. Still, considering Elon Musk's lifelong obsession with Mars, this has to be one of the strangest coincidences in space history!

Grok Build 1.0.8 is out. @SpaceXAI keeps improving the agent workflow, with this release focused heavily on subagents, workflows, and smoother multitasking. Most important changes: • Concurrent subagents now start much faster and no longer freeze the parent session • Opening many subagents at once no longer freezes the UI while loading history • Follow-up messages are sent immediately even while a subagent/task is running • Ctrl+S now stashes your current prompt draft so you can switch tasks and restore it later • /workflow now autocompletes saved workflows and only shows valid actions • MCP servers can request form input or URL consent through the normal question popup • Workflow agent rows now show current context usage instead of cumulative token counts Also included: clearer errors for hallucinated tool calls, status-line fixes, and improved folder downloads.

Grok Build news: @SpaceXAI is back with a banger! Some of the best changes in 0.2.105: • Grok 4.5 is now the default model, with high, medium, and low reasoning effort • /btw now works inside grok --minimal • New /summarize command for instant session summaries • Local shell tools now inherit your normal environment variables, aliases, and functions • Improved long-session compaction • Global rules are now discovered correctly • Smoother scrolling under load and on slow connections Plus a long list of bug fixes. Another seriously strong update.

Grok 4.5 by @SpaceXAI is the most neutral AI model out there. Almost perfectly balanced between the political Left and Right. No other model comes even close to its neutrality. Fantastic achievement, and much harder to pull off than most would realize!
