Grok 4.6 on extra high thinking mode now achieves #1 score on CursorBench!
Grok 4.6 just took the #1 spot on CursorBench 3.2.....and the efficiency is insane
Here's the cost comparison:
• Grok 4.6 Extra High — 70.8% | $2.81/task
• Fable 5 Max — 70.5% | $17.32/task
• Opus 5 Max — 70.0% | $8.23/task
• GPT-5.6 Sol Max — 67.2% | $5.69/task
Grok achieved the highest score while costing roughly 6X less than Fable 5 Max and nearly 3X less than Opus 5 Max per task
That’s what makes Grok so powerful for agents
Top-tier intelligence is great.....but top-tier intelligence that can keep working across long coding tasks without burning ridiculous amounts of compute is even better
Grok’s agentic coding efficiency is insane

Improvements to Grok Build almost every day
X.ai/build
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.

Last week, @SpaceXAI released Grok 4.6, its new frontier model designed for coding, agentic tasks, and knowledge work.
Independent evaluations suggest that SpaceXAI has returned to the AI frontier competition based on both performance and cost.
The economics of Grok 4.6 seem particularly compelling for AI agents. Artificial Analysis estimates that Grok 4.6 costs $0.84 per task on its Intelligence Index, placing it on the Pareto frontier for intelligence-versus-cost.

Starlink is taking over aviation.
The number of airlines announcing deals with Starlink is surging, and the reason is simple: airlines without Starlink now risk losing passengers to competitors offering a much better onboard connectivity experience.
We are already seeing evidence of this on 𝕏, with many passengers saying they are choosing one airline over another specifically because it offers Starlink.

"I used to be super left wing
Then the migrants arrived and started raping everyone,
Now I'm super right wing"
Many such cases

THE ELON EFFECT: Terafab is already attracting more companies to Texas’ Brazos Valley. 🇺🇸
The Greater Brazos Partnership says other companies have started calling since Terafab was announced, hoping to join the region’s growth.
Local leaders estimate Terafab will account for roughly 15% of the region’s total growth over the next decade.
Texas A&M expects at least 50 students to begin its new master’s program in microelectronics and semiconductors this year.
This is the Elon effect. Terafab will help America manufacture advanced AI chips at home for use on Earth and in space.
As Greater Brazos Partnership CEO Tom Johnson said: “This is a winner.”
