Starship is preparing to go to orbit. Flight 14 is targeting to launch as early as Tuesday, September 22, pending regulatory approval → spacex.com/launches/starship…

In just the last 90 days: 1. Grok 4.3 — barely top 10. “xAI is dead beyond compute leases.” 2. Grok 4.5 — massive comeback. “Maybe a chance. But Grok will never catch up to the frontier.” 3. Grok 4.6 — they’re frontier. “Still not top 3.” 4. Grok 4.7 — now top 3 in frontier coding, while being much cheaper & faster. 5. Grok 4.8 next month..... The model machine is just starting up. Grok will be the workhorse of the upcoming agentic era.

This was unexpected. Grok 4.7 scored 100% on my music error detection test, the same as GPT-6 Astra.

Grok 4.7 is behind only Anthropic models on AA-Briefcase, ranking just behind Opus 5 at ~50% of its Cost per Task Grok 4.7’s improvements over Grok 4.6 are clear in AA-Briefcase-Lite, our public due diligence scenario where models are tasked with building market models and target assessment decks. Grok 4.7 gains significantly in Analytical Quality Elo (1698 → 1994) with a slight regression in Presentation Elo (1531 → 1499). API cost to produce example decks: Grok 4.7 (xhigh) ~$8 vs. Grok 4.6 (xhigh) ~$4.40

grok 4.7 is here, and its our best model so far! try it out in cursor, grok build, api or anywhere you get your tokens! curious to hear what you think here's grok 4.6 vs 4.7 building age of empires ii

Grok 4.7 has landed. 🚀 Congrats to @spacexai on its most capable model yet for coding and knowledge work. Proud to support the team with NVIDIA accelerated computing.

Excited to bring 4.7 to you all! Numerics aside, it's incredibly capable in Grok Build/Cursor. We spent a lot of hours on the harness, iterating with some of the greatest engineers in the world. Also, the fast mode has INSANE tps. Happy Grok Building :) Lmk what you think!

Grok 4.7 scores 46 on the Artificial Analysis Intelligence Index to bring SpaceXAI into the top 4 AI labs. Coding Agent Index performance has also improved, overtaking GPT-5.6 Sol Grok 4.7 scores +2 points over Grok 4.6 on the Intelligence Index, with strong performance on agentic knowledge work tasks. We evaluated the new model at xhigh reasoning effort. Congratulations to @spacexai and @ElonMusk on the release! Key takeaways: ➤ Grok 4.7 joins the frontier of agentic knowledge work: Grok 4.7 gains +111 Elo over Grok 4.6 (high) on AA-Briefcase, our private benchmark for long-horizon agentic knowledge work, scoring 1657 Elo and placing it alongside Claude Opus 5 and Claude Fable 5.1 at the frontier. On GDPval-AA, it scores 1695 Elo, +90 ahead of Grok 4.6 (high). ➤ A leap in coding agent performance: Grok 4.7 (xhigh) with Grok Build scores 56 on the Artificial Analysis Coding Agent Index, up +9 points from Grok 4.6 (xhigh). Among models in their native harnesses, Grok 4.7 + Grok Build now ranks 4th, behind only Claude Fable 5.1, GPT-6 Astra, and Claude Opus 5. ➤ Incremental performance changes elsewhere: Outside of agentic knowledge work, Grok 4.7 broadly matches Grok 4.6 (high) on the other Intelligence Index tasks. It improves on Terminal-Bench 4.0 (+4.5 percentage points) and GDP.pdf (+3.0 p.p.), with regressions on AA-LCR (-3.7 p.p.) and AutomationBench-AA (-1.1 p.p.). ➤ High token use across tasks: Grok 4.7's gains come with higher token usage. Grok 4.7 (xhigh) uses approximately 81k output tokens per Intelligence Index task, compared with 36k for Grok 4.6 (high) and 27k for GPT-6 Astra (max) - 125% and 196% more, respectively. Other model details: ➤ Context window of 500k tokens, unchanged from Grok 4.6 ➤ Pricing of $2/$6 per 1M input/output tokens with cache hits discounted to $0.50 per 1M tokens, matching Grok 4.6 ➤ Configurable reasoning effort spans low to xhigh. Our evaluation uses xhigh.

Grok 4.7 works longer on difficult tasks, checks its work more carefully, and comes with our strongest safeguards to date.

Just a reminder that GLM 5.3 Flash, DeepSeek V4.1 Flash, Qwen 3.8 Next Flash, and even Qwen 3.8 27B are all outperforming (in both intelligence and capabilities) every model that was considered "frontier intelligence" in Xmas 2025 (just 10 months ago) Opensource AI is on fire

This is literally my new workflow now: Realtime Research → Grok Bot Planning & Orchestration→ Grok Bot Day-to-day Coding/Debug → Grok Build + Grok 4.6 Write & Run Tests → Grok Build + Grok 4.6 Complex Coding/Debug → GPT-6 Astra Frontend → Fable 5.1 Bookmark this.

Tesla helped save a man from jail. Kevin Finley was arrested at gunpoint for allegedly fleeing police. His Tesla captured the key moments, showing why he never saw the unmarked police car. Nearly two years later, the judge watched the video and found him not guilty.
