Anthropic Load & Scale

Overview

Capacity planning and load testing for Claude API integrations. Key constraint: your rate limits (RPM/ITPM/OTPM) are the ceiling, not your infrastructure.

Capacity Planning

# Calculate required tier based on traffic
def plan_capacity(
    requests_per_minute: int,
    avg_input_tokens: int,
    avg_output_tokens: int,
    model: str = "claude-sonnet-4-20250514"
) -> dict:
    itpm = requests_per_minute * avg_input_tokens
    otpm = requests_per_minute * avg_output_tokens
