AI API Rate Limit Calculator

Calculate rate limits (RPM/TPM/RPD) across major AI vendors, smartly plan call strategies to avoid throttling

Calculator Interface

Interactive calculator will be available soon

Features

  • ✓ Covers latest quota data for 50+ vendors including OpenAI, Claude, Gemini, DeepSeek
  • ✓ Supports RPM (requests/min), TPM (tokens/min), RPD (requests/day) calculation
  • ✓ Smart planning of concurrency and call intervals to maximize throughput
  • ✓ Simulate real business scenarios, forecast peak load and throttling risk
  • ✓ Generate optimal call strategy code (Python/Node.js/Go)

How to Use

  1. Select AI vendor and specific model (auto-loads quota data)
  2. Input business parameters: average tokens, expected QPS, peak multiplier
  3. Click calculate to view throttling thresholds and recommended concurrency
  4. Export call strategy code or configure to gateway

FAQ

What are RPM and TPM?

RPM (Requests Per Minute) is the per-minute request limit; TPM (Tokens Per Minute) is the per-minute token limit. Both apply simultaneously; exceeding either triggers 429 errors.

Is there a big difference between free and paid quotas?

Yes. For example, OpenAI free tier has only 3 RPM, while paid Tier 1 reaches 500 RPM. Production environments should use paid accounts.

How to avoid hitting rate limits?

Use exponential backoff retries, request queues, multi-key rotation, cache repeated requests. This tool generates corresponding strategy code.

What are the quotas for different Tiers?

For OpenAI: Tier 1 (paid $50+) has 500 RPM/300K TPM; Tier 2 (paid $100+) has 5000 RPM/6M TPM. Refer to official site for specifics.

Can it calculate combined limits for multiple keys?

Yes. Input multiple keys and their Tiers; the tool auto-calculates aggregate limits and provides load balancing suggestions.
