Grok 4.5 is leading on actual professional work
In Snorkel AI’s benchmark, Grok 4.5 combined with Grok Build was tested against GPT 5.5 and Claude Opus 4.8 across nearly 2,000 expert-created workplace tasks involving real documents, spreadsheets, presentations and professional analysis
Grok outperformed both GPT 5.5 and Claude Opus 4.8 overall, while leading by even wider margins across several high-judgment fields:
• Education: 58%
• Legal work: 40%
• Quality assurance: 37%
• Healthcare: 35%
It also recorded the lowest failure rate across every error category Snorkel measured, including missing analysis, incorrect recommendations, poor structure and missing sources
The most important result is not simply that Grok completed more tasks
It produced better professional deliverables, made fewer critical mistakes and provided more specific, actionable recommendations where competing models often returned generic work
Grok 4.5 is proving that real-world usefulness matters more than benchmark scores alone
