Feature Request: Interactive Cost Calculator

Description

Add an interactive cost calculator to help users estimate and compare pricing across different models and usage scenarios.

Proposed Features

• Token-based Calculator: Input prompt and completion token counts to see estimated costs
• Batch Processing Estimator: Calculate costs for processing large datasets or batch operations
• Multi-model Comparison: Compare costs across multiple models for the same workload
• Budget Projections: Monthly/yearly cost projections based on estimated usage

Implementation Ideas

• Add a calculator modal or sidebar panel
• Include common presets (e.g., "1M tokens daily", "Chat application", "Document processing")
• Show cost breakdown with visual charts
• Export cost estimates as CSV/PDF reports
• Add "tokens from text" estimator using simple tokenization approximation

Example Interface

Prompt Tokens: [____] 
Completion Tokens: [____]
Requests per day: [____]

Estimated Costs:
- Model A: .XX/day, .XX/month
- Model B: .XX/day, .XX/month
