Compare pricing across multiple LLM models side by side.

Args:

• models (string[]): Array of model IDs or names to compare (2-10 models)

Returns: Side-by-side comparison table with input/output costs, context windows, and relative cost differences.

Examples:

• ["gpt-5", "claude-sonnet-4.6"] → Compare OpenAI vs Anthropic pricing

• ["gpt-5-mini", "gemini-3-flash", "claude-haiku-4.5"] → Compare budget models

Args:

• model (string): Model ID or name

• input_tokens (number): Number of input tokens (0 to 100B)

• output_tokens (number): Number of output tokens (0 to 100B)

Returns: Cost breakdown with input cost, output cost, and total cost in USD.

Examples:

• model="gpt-5", input_tokens=1000, output_tokens=500 → Cost for a typical API call

• model="claude-sonnet-4.6", input_tokens=100000, output_tokens=4000 → Cost for a long context call
