DeepSeek API Quickstart: Call It from Anywhere in Under 5 Minutes

Short summary

DeepSeek-V4-Flash ($0.056 per million input tokens) and R1 ($0.20) are now accessible via OpenAI-compatible API through APIRouter, requiring just two changes to standard OpenAI SDK code. The guide covers setup, pricing comparison with Qwen/Kimi/GLM/MiniMax, error handling, and a five-prompt evaluation strategy. Route fast tasks to V4-Flash and complex reasoning to R1 only when cost-benefit justifies it.
