## litellm Key Advantages
- The fastest, litest AI Gateway. Rust core with Python SDK. Call 100+ LLM APIs in OpenAI (or nat (61,519 stars, +95.8/day velocity in Python)
- Pricing model: Open Source (MIT)
- Production trade-off: Self-hosted Python runtime requires explicit environment configuration and API key isolation

## Helicone AI Key Advantages
- 1-line proxy header integration providing instant LLM cost caching, latency p99 tracking, and prompt threat detection.
- Pricing model: Free Tier / $20/seat/mo Pro
- Production trade-off: Proxy-based routing adds ~12-18ms edge hop overhead unless deployed via self-hosted Cloudflare Workers.
