Grok 4.5 Review: Agentic Speed at Half the Price
xAI's Grok 4.5 tops AutomationBench and costs 80% less per agentic task than Opus 4.8, but neutral coding benchmarks and a doubled hallucination rate complicate the story.
Grok 4.5
Grok 4.5 is xAI's 1.5-trillion-parameter V9 MoE model, publicly launched July 8 at $2/M input - cheap, fast, and token-efficient, though neutral harness benchmarks put it well behind Fable 5 and Opus 4.8 on coding.
Grok 4.5 Ships - Token Efficiency Is the Real Edge
Grok 4.5 goes public with real benchmarks: behind Fable 5 on coding evals, but a 4.2x token efficiency gap that changes the cost math for high-volume pipelines.
Grok 4.1 Fast
Grok 4.1 Fast is xAI's agent-optimized model with a 2M-token context window, #1 ranking on tau-bench Telecom, and one of the lowest input prices among frontier-adjacent APIs at $0.20/M tokens.
SpaceX AI Device - Real Prototype or Investor Theater?
The WSJ says SpaceX showed investors a Grok-powered AI handset before its IPO. Musk called it false. We examine the hardware stack and what the denial actually means.
Grok 4.5 Enters Beta with Unverified Opus Claims
