Deepseek V4

这是一款终端工具，可调用DeepSeek V4的Flash（快廉）和Pro（强推理）两款模型，具备单轮问答、带推理轨迹的思考模式、多轮对话功能，还可查看模型与定价。日常问答、写作、编码适合用Flash，复杂推理、数学问题选Pro。需配置API密钥，基于Python脚本实现，兼容OpenAI SDK，输入为终端命令，输出AI回复。

DeepSeek V4

Use DeepSeek V4 Flash and Pro directly from your terminal — one-shot questions, deep reasoning with thinking mode, and multi-turn chat. No special CLI required; uses the OpenAI-compatible API via a small Python script.

Setup

1. Get API key: https://platform.deepseek.com/api_keys

2. Set environment variable:

export DEEPSEEK_API_KEY=your_key_here
# Add to ~/.zshrc or ~/.bashrc to persist

Models

Model	ID	Best for	Price (input/output)
V4 Flash ⚡	`deepseek-v4-flash`	Q&A, writing, coding, summaries	$0.014 / $0.028 per 1M
V4 Pro 🚀	`deepseek-v4-pro`	Hard reasoning, math, deep analysis	$0.174 / $0.348 per 1M

Both support 1M token context. Cache hits are 10× cheaper.

Legacy aliases (deepseek-chat → flash, deepseek-reasoner → pro) deprecated 2026-07-24.

Commands

One-shot question (Flash — fast & cheap)

uv run {baseDir}/scripts/ask.py "Explain the difference between V4 Flash and V4 Pro"

One-shot with Pro model

uv run {baseDir}/scripts/ask.py "Write a merge sort in Rust" --model pro

Thinking mode (Pro with visible reasoning trace)

uv run {baseDir}/scripts/ask.py "Prove that there are infinitely many primes" --think

Multi-turn chat

uv run {baseDir}/scripts/chat.py --model flash
uv run {baseDir}/scripts/chat.py --model pro --think

Show models & pricing

uv run {baseDir}/scripts/models.py

Model Selection Guide

Use Flash when:

Everyday Q&A and explanations
Writing, editing, translation
Code generation and review
Summarization and classification
Cost is a priority

Use Pro when:

Multi-step math or logic problems
Complex debugging or architecture decisions
Deep research and analysis
You want to see the reasoning process (--think)

Tips

Thinking mode (--think) streams the internal reasoning before the final answer — useful for hard problems and to verify correctness
System prompt: --system "You are a concise assistant" to set tone
No streaming: --no-stream for cleaner output in scripts
