Large Context Document Analysis

Summarize this 150,000-word financial report and forecast trends in revenue growth. [Paste massive S-1 document here]

Key insights: Revenue grew 25% YoY from $500M to $625M, driven by cloud services; Q4 forecast predicts 18% growth to $735M based on historical trends and market expansion. Risks include supply chain issues. Overall bullish outlook with 22% CAGR projected over 3 years.

Reduced Hallucination Q&A

Does this 500-page codebase support implementing user authentication via OAuth? Provide exact line references or say if unsupported.

No, the codebase does not support OAuth authentication. It uses JWT tokens only (lines 145-210 in auth.py and 320-350 in server.js). No OAuth libraries or endpoints present.

Tool Use Function Calling

Using system prompt: You are a workflow orchestrator. Translate this request into API calls: "Check sales database for Q1 totals and email summary to team."

First, query sales DB API: GET /sales/q1/totals. Result: $2.1M. Then, invoke email function: send(to: team@company.com, subject: Q1 Sales Summary, body: Totals $2.1M). Workflow complete.
