The post Grok 4.5 Tops Agent Test, Backing Musk’s Opus-Class Claim appeared on BitcoinEthereumNews.com. Elon Musk called Grok 4.5 an Opus-class model that runs faster and costs less. An independent, agentic benchmark now provides real backing for that claim. On Artificial Analysis’s AutomationBench-AA, Grok 4.5 ranked first with a 51.4% score while costing $0.34 per task. It beat both Claude Fable 5 (48.6%) and Claude Opus 4.8 (48.5%). AutomationBench-AA Score of AI Models.

Musk’s pitch rested on early internal evaluations. AutomationBench-AA changes that. Artificial Analysis runs the benchmark independently and keeps its task set private to prevent contamination. The test spans 657 tasks across 40 simulated apps, including Gmail, Slack, Salesforce, and HubSpot. It scores the share of objectives an agent completes without brea
