Crate deepseek_sdk 

DeepSeek API client for Rust.

This crate provides:

• Chat completions (/chat/completions)
• FIM completions (beta, /beta/completions)
• Model listing (/models)
• Account balance (/user/balance)

Streaming is supported in both async and blocking forms. The async API returns a tokio::mpsc::Receiver, while the blocking API returns an iterator that yields stream items.

use deepseek_sdk::chat::request::{ChatMessage, ChatRequestBuilder, Thinking};
use deepseek_sdk::{DeepSeekClient, DeepSeekRequest, DEFAULT_BASE_URL};

let req = ChatRequestBuilder::default()
    .client(DeepSeekClient::new("sk-...", DEFAULT_BASE_URL.clone()))
    .model("deepseek-v4-flash")
    .message(ChatMessage::User { content: "Hi".into(), name: None })
    .thinking(Thinking::disabled())
    .build()?;
let _resp = req.send().await?;
