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

    # Estimate monthly cost
    pricing = {
        "claude-haiku-4-20250514": (0.80, 4.00),
        "claude-sonnet-4-20250514": (3.00, 15.00),
        "claude-opus-4-20250514": (15.00, 75.00),
    }
    rates = pricing[model]
    cost_per_request = (avg_input_tokens * rates[0] + avg_output_tokens * rates[1]) / 1_000_000
    monthly_cost = cost_per_request * requests_per_minute * 60 * 24 * 30

    return {
