Quick Start
Connect DeepSeek V4 Flash API without changing the OpenAI-style request shape. Route classification, extraction, and routine coding turns to standard mode, then reserve max reasoning for harder cases. Explicit output limits help control long reasoning traces.
Get your API key
Create an APINEED key for DeepSeek V4 Flash API and keep it in an environment variable.
export API_NEED_API_KEY=sk-apineed-v1-...Make your first request
Use deepseek-v4-flash for DeepSeek V4 Flash API with the APINEED API. The request shape is compatible with OpenAI chat completions, so most SDKs only need a base URL change.
TypeScript SDKPythoncURLOpenAI SDK
import OpenAI from "openai";
const client = new OpenAI({
