Is Grok 5 Really The Smartest AI Ever?
Elon Musk promised Grok 5 would be the smartest AI ever. With two missed deadlines and no independent benchmark, we check the record. In November 2025, Elon Musk told investors Grok 5 would be the smartest AI in the world by a significant margin. As of November 2026, that claim has no release date, no model card, and no independent evaluation behind it. The only backed promise is hardware scale: xAI's Colossus clusters came online in 122, 91, and 64 days respectively, far faster than the industry standard of roughly two years for a 100-megawatt data center. Yet Musk's own wording has quietly shrunk. In October 2025 he claimed a 10 percent chance of AGI; by September 2026 his roadmap admitted Grok 4.7 was "roughly on par with Opus 5.0, not 5.1," with two versions (4.8 and 4.9) still needed before Grok 5, and Grok 5 itself described as "maybe better than anything. We shall see." When xAI's current released model, Grok 4.7, is measured by Artificial Analysis on their Intelligence Index, a standardized benchmark across coding, knowledge, and science, it scores 35. Gemini 4 Carbon, the leader, scores 60. Grok 4.7 also generated 148 million output tokens versus a median of 72.6 million, making its advertised "half price" claim ($2 per million input, $6 per output tokens) actually cost $7.77 per task on average, one cent more than the top model's $7.76. Colossus two is planned to run at roughly 50-50 split between internal training and rental to customers like Google and Anthropic. This video walks through what xAI and SpaceX have officially filed, how the hardware roadmap actually works, why bigger models do not automatically win, and what three concrete signals would validate the Grok 5 claim. For builders, investors, and anyone following AGI progress through the claims versus the benchmarks.

Each video takes one tool, model, or workflow and shows how it works in a few focused minutes, with the real benchmarks and real costs. We go deep on Claude Code and Cursor for AI coding, AI agents and MCP servers, the open-source AI tools and GitHub repos most people miss, RAG and vector search, fine-tuning, and running local LLMs on your own machine with Ollama and LM Studio. We compare models like ChatGPT and Claude, test AI automation with Zapier, Make, and n8n, and flag the tools that actually ship.
