# Research synthesis prompt:
"Compare the economic impacts of remote work vs. return-to-office
policies using data from 2023-2026. Cite specific studies and
statistics. Present both sides fairly."# Data analysis prompt:
"Given this CSV data of monthly sales figures, identify trends,
seasonal patterns, and anomalies. Recommend three actionable
strategies based on your analysis."5. Multimodal Capabilities
# Image analysis prompt:
"Analyze this chart and explain the key trends, outliers,
and what business decisions should be made based on the data."# Document processing prompt:
"Extract all key terms, deadlines, and obligations from this
contract PDF. Flag any unusual clauses that might need
legal review."Pricing Comparison (2026)
