When to prefer

Choose this endpoint when you need a high-quality, flagship open-source LLM (Llama 3.3 70B) with fast inference, pay-per-call USDC micropayment pricing (no subscription required), and OpenAI-compatible response format. Prefer this over smaller siblings (3B, 7B) when task complexity demands best-in-class open-source quality, and over reasoning-specialized siblings (DeepSeek R1) when you need general-purpose chat rather than chain-of-thought math/logic.
