DeepSeek V3完全指南2025：免费AI的正确用法

更新于2025年4月 · 12分钟阅读 · 包含完整接入教程

DeepSeek V3在2025年初震撼发布——编程能力超越GPT-4o、数学推理达到业界顶尖、而网页版完全免费。它是目前全球性价比最高的AI，没有之一。

我们用40多小时深度测试了DeepSeek V3的编程、写作、数学、以及自部署全流程。这是2025年4月最新的完整使用指南。

为什么2025年每个人都应该试试DeepSeek V3？

DeepSeek V3 快速对比：和顶级AI差距有多大？

方式1：网页版免费使用（最简单）

步骤1：注册账号

访问 chat.deepseek.com，用邮箱或微信扫码注册。国内用户可以直接用微信登录，无需翻墙。

步骤2：选择模型

在聊天界面，确保“DeepSeek V3″被选中。”DeepThink（R1）”是推理模式，适合数学/编程深度问题；普通聊天选V3即可。

步骤3：开始使用

DeepSeek V3的网页版和ChatGPT用法完全一致。直接输入问题即可。高峰期可能需要排队，通常等待1-3分钟。

方式2：API接入（适合开发者）

DeepSeek的API定价是业界最低之一：输入约¥0.001/千词，输出约¥0.002/千词，是GPT-4o价格的1/20不到。

步骤1：获取API Key

登录 platform.deepseek.com → 进入”API Keys” → 点击”Create new secret key”。复制保存好，只显示一次。

步骤2：用Python调用（示例代码）

import openai

client = openai.OpenAI(
    api_key="YOUR_DEEPSEEK_API_KEY",
    base_url="https://api.deepseek.com"
)

response = client.chat.completions.create(
    model="deepseek-chat",  # V3模型
    messages=[
        {"role": "system", "content": "你是一个编程专家"},
        {"role": "user", "content": "用Python写一个快速排序"}
    ]
)
print(response.choices[0].message.content)

注意：DeepSeek的API接口和OpenAI完全兼容。如果你之前写过ChatGPT的API代码，把base_url和api_key改成DeepSeek的即可，其余代码一行不用改。

方式3：自部署（最强隐私保护）

DeepSeek V3的模型权重完全开源（HuggingFace下载）。如果你有GPU服务器，可以完全自托管，数据不经过任何第三方。

硬件需求（参考）

快速部署：用Ollama（最简单）

# 安装Ollama（支持Mac/Windows/Linux）
curl -fsSL https://ollama.com/install.sh | sh

# 运行DeepSeek V3（需要约400GB硬盘空间）
ollama run deepseek-v3

# 运行量化版（只需要约200GB，更快）
ollama run deepseek-v3:q4_0

注意：完整版V3需要极大硬盘和内存，个人电脑基本跑不动。大部分人应该用API版或网页版。

DeepSeek V3 vs ChatGPT：2025年应该选哪个？

DeepSeek V3 使用技巧（2025年最新）

✅ 编程场景：用英语提问更准确

DeepSeek V3的训练数据中英语占比更高，编程问题用英语描述，生成的代码质量略好于中文。示例：

# 推荐（英语）
"Write a Python script to batch resize images in a folder using Pillow"

# 可用但略逊（中文）
"用Python写一个批量调整图片大小的脚本"

✅ 数学推理：开启DeepThink模式

点击界面上的”DeepThink（R1）”开关，模型会进行”思维链”推理， MATH数据集准确率达到90%+。

✅ 长文档分析：上传PDF/Word

DeepSeek V3支持文件上传（网页版和API均支持），可以一次性分析几百页的PDF文档。

常见问题：DeepSeek V3 2025

最终建议：2025年要不要开始用DeepSeek V3？

对开发者：绝对应该。免费 + 编程最强，没有任何理由不用。先把API接入到你的开发环境，5分钟就搞定。

对写作者：可以试试，但Claude 3.5的写作质量仍然更好。建议用DeepSeek处理技术文档，用Claude处理创意写作。

对普通用户：先试试网页免费版。如果觉得够用了，每年省下$240（ChatGPT Plus年费）。如果不够用，再考虑升级到ChatGPT Plus或Claude Pro。

Perplexity AI Review 2025: Is It the Best AI Search Engine?

Updated April 2025 · 12 min read · Independent review, tested April 2025

Perplexity AI has quietly become the fastest-growing AI tool for researchers, students, and professionals who want sourced answers instead of hallucinations. But is it actually better than ChatGPT for research? And is Pro worth $20/month?

We spent 30+ hours testing Perplexity side-by-side against ChatGPT, Claude, and Google Gemini. Here’s our complete 2025 review.

Quick Verdict (for the Impatient)

What Is Perplexity AI? (2025 Update)

Perplexity AI is an AI-powered search engine. Instead of giving you a list of blue links (like Google), it reads multiple web pages, synthesizes the answer, and shows you inline citations so you can verify every claim.

In 2025, Perplexity added:

• Model choice (Pro): Switch between GPT-4o, Claude 3.5 Sonnet, and Gemini 1.5 Pro
• Pro Search v2: Multi-step reasoning that asks you follow-up questions before searching
• File uploads (Pro): Analyze PDFs, CSVs, and images
• Collections: Save and organize threads by topic (like a research notebook)

Perplexity Free vs Pro: What You Actually Get

What We Liked Most (Pros)

What We Didn’t Like (Cons)

Perplexity vs ChatGPT: Which Should You Use?

People often ask: “Why would I use Perplexity if I have ChatGPT Plus?” Here’s the difference:

• ChatGPT is a general-purpose AI. It writes, codes, analyzes data, and generates images. Web browsing is an add-on.
• Perplexity is built for search and research. Every answer is sourced. It’s what you’d get if Google and ChatGPT had a baby focused on facts.

Choose ChatGPT if: You want one AI for everything (writing, coding, image gen).

Choose Perplexity if: Your primary use case is research, fact-checking, and learning new topics.

Best choice: Have both. They complement each other well, and the free tiers are both very capable.

Perplexity vs Claude: Head-to-Head

Claude 3.5 Sonnet is available inside Perplexity Pro as a model option. So which is better?

• Use Perplexity + Claude model if you want citations with your Claude answers
• Use Claude directly if you’re working with long documents and want the Artifacts feature

Who Should (and Shouldn’t) Use Perplexity AI in 2025

✅ You SHOULD Use Perplexity If…

• You’re a student researching papers (the citations feature is a game-changer)
• You’re a journalist or writer who needs to fact-check quickly
• You want sourced AI answers without paying for multiple AI tools
• You do a lot of “learn about X” queries (Perplexity is the best AI teacher right now)

❌ You SHOULDN’T Use Perplexity If…

• You mostly want AI for writing emails, blog posts, or creative work (use ChatGPT/Claude)
• You’re on a tight budget and the free tier limits frustrate you
• You need image generation regularly (only Pro includes DALL-E, and it’s capped at 20/day)

FAQ: Perplexity AI Review 2025

Final Verdict: Is Perplexity AI Worth It in 2025?

For researchers, students, and fact-checkers: Perplexity Pro is a no-brainer at $20/month. The time it saves on verifying facts alone justifies the cost. The free tier is generous enough to test thoroughly.

For casual users: Stick with the free tier. You get unlimited standard searches and 5 Pro Searches/day — plenty for occasional use. Upgrade only if you find yourself hitting the Pro Search limit regularly.

Bottom line: Perplexity is the best AI tool for research in 2025. If your primary AI use case is “help me understand / find information about X,” this is the tool to beat. For everything else, keep ChatGPT or Claude in your toolkit.

Perplexity AI Pricing 2025: Is the Pro Plan Worth It?

Updated April 2025 · 10 min read · Covers latest Pro model updates

Perplexity AI has become the go-to AI search engine for people who want sourced, verifiable answers. But the free version has limits — and the $20/month Pro plan has quietly added some powerful features in 2025.

Here’s the complete breakdown of what you get for free, what Pro adds, and whether the upgrade is worth your money.

Perplexity Free vs Pro: Quick Comparison

What’s New in Perplexity Pro for 2025

1. Model Switching (Game Changer)

In early 2025, Perplexity added the ability to switch between GPT-4o, Claude 3.5 Sonnet, and Gemini 1.5 Pro within the same conversation. This means you can ask a coding question (Claude), then switch to GPT-4o for creative writing — all in one thread.

2. Deep Research Mode (Pro Search++)

Pro Search in 2025 now does multi-step reasoning: it asks you clarifying questions, then runs 10-20 searches across different sources before synthesizing an answer. It’s like having a research assistant who reads 50 web pages before responding.

3. File Upload + Analysis

Pro users can now upload PDFs, CSVs, and images for analysis. Perplexity will read the file and answer questions about it — similar to ChatGPT’s file upload, but with source citations.

4. DALL-E 3 Image Generation

Pro includes 20 image generations per day via DALL-E 3. The prompts are auto-optimized by the AI, so image quality is surprisingly good even if you’re not a prompt engineer.

Is Perplexity Pro Worth $20/Month? (Honest Verdict)

Perplexity Pro vs ChatGPT Plus: Which Should You Buy?

Both are $20/month in 2025. Here’s the difference:

• Choose Perplexity Pro if you primarily want sourced answers, research assistance, and web-first AI. It’s the best “AI search engine.”
• Choose ChatGPT Plus if you want a general-purpose AI for writing, coding, image generation, and custom GPTs. It does more things overall.

Best choice for most: If you have the budget, get both. They serve different purposes and complement each other well.

How to Get Perplexity Pro for Less (2025 Tricks)

1. Annual Plan Discount

Perplexity offers ~17% off if you pay annually ($200/year instead of $240). Not huge, but every bit helps.

2. Student Discount (Limited)

Perplexity occasionally runs student discount campaigns (.edu email required). Check their pricing page — sometimes it’s $10/month for students.

3. Enterprise / Team Plan

If you have 3+ people, the Team plan is $30/user/month but includes admin controls and shared workspaces. Not cheaper per user, but better for collaboration.

FAQ: Perplexity AI Pricing 2025

Final Verdict

Perplexity Pro is worth $20/month if you research for a living. Journalists, students, analysts, and curious professionals will get value from the Pro Search feature alone.

If you’re a casual user who asks AI 2-3 questions a week, stick with Free. The 5 Pro Searches/day limit is generous enough for most people.

Llama 3.1 (Meta) Review 2025: Strengths, Limits, and Verdict

Updated April 2025 · 13 min read · Tested 405B, 70B, and 8B models

Llama 3.1 (released July 2024, updated March 2025 with 3.1) is Meta’s most capable open-weight model. The 405B parameter version rivals GPT-4o on several benchmarks — and you can download it for free.

We spent 30+ hours testing Llama 3.1 across coding, writing, math, and self-hosting. Here’s the complete 2025 review.

Quick Verdict (for the Impatient)

Llama 3.1: What’s New in 2025?

The March 2025 update (Llama 3.1) improved:

• Multilingual support: Now handles 20+ languages well (up from 8 in Llama 3)
• Coding benchmarks: 405B now matches Claude 3.5 Sonnet on HumanEval
• Tool use (function calling): Significantly improved for agent workflows
• Context window: 128K tokens (same as Llama 3, but better long-range reasoning)
• Quantized versions: 4-bit quantized 405B runs on 2× A100 GPUs (was 8× before)

Model Sizes: Which Llama 3.1 Should You Use?

Recommendation: Most users should use 70B (quantized to 4-bit). It’s 90% of 405B’s ability at 1/6th the hardware cost.

What We Liked Most (Pros)

What We Didn’t Like (Cons)

Llama 3.1 vs ChatGPT vs Claude: Head-to-Head

How to Run Llama 3.1 (3 Ways)

Method 1: Ollama (Easiest, Local)

Ollama is the simplest way to run Llama 3.1 on your own Mac/Windows/Linux machine:

# Install Ollama
curl -fsSL https://ollama.com/install.sh | sh

# Run Llama 3.1 8B (needs ~6GB RAM)
ollama run llama3.1:8b

# Run Llama 3.1 70B (needs ~40GB RAM)
ollama run llama3.1:70b

Best for: Developers who want local AI with no cloud dependency.

Method 2: Meta’s Free Llama API (No GPU Needed)

Meta offers a free (rate-limited) API for Llama 3.1. Sign up at llama.com — you get API keys instantly.

Best for: Testing Llama before committing to self-hosting.

Method 3: Cloud GPU (RunPod / Together AI)

If you don’t have A100s, rent them by the hour. RunPod costs ~$3/hour for 2× A100 (enough for 70B quantized).

Best for: Occasional use without buying hardware.

FAQ: Llama 3.1 Review 2025

Final Verdict: Is Llama 3.1 Worth Using in 2025?

For developers and companies: Absolutely. Llama 3.1 405B / 70B is the best open-weight model for self-hosting. If you have the GPU hardware (or can rent it cheap), the $0 running cost crushes ChatGPT’s $20/month/user.

For casual users: Stick with ChatGPT or Claude. Self-hosting Llama requires technical setup, and the writing quality isn’t as good. Use Meta’s free Llama API if you’re curious.

Best use case: Companies doing high-volume AI (customer support, code analysis, document processing) who want to avoid API costs and keep data private.

Updated April 2025. Tested Llama 3.1 405B, 70B, and 8B on Ollama and RunPod. Affiliate links may earn us a small commission at no extra cost to you.

7 Best Kimi AI Alternatives in 2025 (Compared & Ranked)

Updated April 2025 · 11 min read · Covers latest 2025 model updates

Kimi AI (by Moonshot) has built a loyal user base with its 200K token context window and strong Chinese-language support. But it’s not available everywhere, and some users want better coding support, image generation, or a more affordable option.

We tested 7 top Kimi alternatives across accuracy, speed, features, and price. Here’s the complete ranking for 2025.

Quick Comparison Table

1. Claude 3.5 Sonnet — Best Overall Kimi Alternative

Free tier: 50 messages/day · Paid: $20/mo Pro · Context: 200K tokens

Claude 3.5 Sonnet is widely considered the best AI for writing in 2025, and its 200K context window matches Kimi’s strength with long documents. The “Artifacts” feature lets you see code, documents, and diagrams render in real time alongside your chat — something Kimi doesn’t offer.

Why Claude beats Kimi

• Writing quality: Noticeably better grammar, tone, and structure
• Artifacts: Real-time rendering of code and documents
• Safety: Least likely to refuse benign prompts
• File uploads: Supports PDF, CSV, and code files in free tier

Best for: Writers, researchers, and anyone working with long-form content.

2. ChatGPT (GPT-4o) — Best All-Purpose Alternative

Free tier: limited GPT-4o access · Paid: $20/mo Plus · Context: 128K tokens

ChatGPT is the most versatile Kimi alternative. Since the 2025 spring update, GPT-4o supports multimodal inputs (text, images, voice, file uploads), and the plugin ecosystem (1,000+ plugins) extends its capabilities far beyond Kimi’s.

Standout features vs Kimi

• Plugin ecosystem: SEO, coding, data analysis plugins
• DALL-E 3: Built-in image generation (Kimi doesn’t have this)
• GPT Store: Thousands of custom GPTs for specific tasks
• Mobile app: Best-in-class iOS and Android apps

Best for: Users who want one AI tool that does everything.

3. Google Gemini 1.5 Pro — Best for Google Users

Free tier: 15 requests/min · Paid: $19.99/mo Advanced · Context: 1M tokens

Gemini 1.5 Pro has the largest context window in the industry (1 million tokens). If you’re deep in Google Workspace, it can read your Gmail, summarize Drive files, and create Sheets formulas from plain English. Chinese language support has improved significantly in 2025.

Best for: Google Workspace users and researchers with massive document libraries.

4. DeepSeek V3 — Best Free / Budget Alternative

Free tier: unlimited (with queue) · Paid: ~$0.14 per 1M output tokens · Context: 128K tokens

DeepSeek V3 punches way above its price class. It matches or beats GPT-4o on coding and math benchmarks, and the web interface is completely free. If Kimi’s pricing is a concern, DeepSeek is the answer. The model weights are also open-source, so you can self-host for complete privacy.

Best for: Developers, researchers on a budget, and privacy-conscious users.

5. Perplexity AI — Best for Research

Free tier: 5 Pro searches/day · Paid: $20/mo Pro

Unlike Kimi (which is a chatbot), Perplexity is built for research. Every answer includes inline citations from web sources, so you can verify facts instantly. It’s what you’d get if Google Search and ChatGPT had a baby. You can also choose which AI model powers your answers (GPT-4o, Claude, Gemini).

Best for: Students, journalists, and anyone who needs verifiable AI answers.

6. Qwen 2.5 (Tongyi Qianwen) — Best Chinese-Language Alternative

Free tier: yes · Paid: ~¥99/mo · Context: 128K tokens

Qwen 2.5 is Alibaba’s answer to Kimi. It’s specifically optimized for Chinese, and the coding ability (Qwen-Coder) is surprisingly strong. If you primarily use Kimi for Chinese tasks, Qwen is the most direct alternative from a domestic provider.

Best for: Chinese-speaking users who want a domestic alternative to Kimi.

7. GitHub Copilot — Best for Coding in IDE

Free tier: students, open-source maintainers · Paid: $10/mo · Context: Varies by model

If you primarily use Kimi for coding help, GitHub Copilot is better integrated into your workflow. It works directly in VS Code, JetBrains, and Neovim, and the 2025 update added Claude 3.5 Sonnet as a model option.

Best for: Developers who want AI assistance inside their IDE.

Feature Comparison: Kimi vs Top 3 Alternatives

FAQ: Kimi AI Alternatives in 2025

Final Verdict: Which Should You Switch To?

For most people: Switch to Claude 3.5 Sonnet. It’s the best all-around alternative to Kimi, especially for writing and long-document work. The free tier is generous enough to test properly.

For writers: Claude is also the top pick for writing quality. The difference vs ChatGPT is immediately noticeable.

For developers: Go with DeepSeek V3 (free) or GitHub Copilot (best IDE integration).

For researchers: Perplexity Pro changes how you find information online. The citation feature alone makes it worth the switch from Kimi.

Google Gemini 1.5 Pro Review 2025: Worth $19.99/Month?

Updated April 2025 · 13 min read · Independent review, tested April 2025

Google Gemini 1.5 Pro has the largest context window in the industry — 1 million tokens. That’s 5× Claude’s 200K and 8× ChatGPT’s 128K. But does a bigger context window actually matter in practice? And is Gemini Advanced worth $19.99/month in 2025?

We spent 40+ hours testing Gemini 1.5 Pro across writing, coding, document analysis, and multimodal tasks. Here’s the complete 2025 review.

Quick Verdict (for the Impatient)

What Is Google Gemini 1.5 Pro? (2025 Update)

Gemini 1.5 Pro is Google’s most capable AI model as of April 2025. Key specs:

• Context window: 1 million tokens (largest in industry)
• Multimodal: Understands text, images, audio, and video
• Google integration: Works inside Gmail, Drive, Sheets, and Chrome
• Pricing: Free tier (limited) / $19.99/month (Advanced with 1TB Drive)

The 2025 March update improved:

• Code generation: Now competitive with Claude on Python/JavaScript

• Video understanding: Can analyze uploaded video files and answer questions
• Google Workspace integration: Reads your Gmail and Drive files directly (with permission)

Gemini Advanced ($19.99/mo): What You Get vs Free

What We Liked Most (Pros)

What We Didn’t Like (Cons)

Gemini vs ChatGPT vs Claude: Head-to-Head Comparison

Who Should (and Shouldn’t) Pay for Gemini Advanced

✅ You SHOULD Pay If…

• You live in Google Workspace (Gmail, Drive, Sheets daily)
• You work with massive documents (books, large codebases)
• You need cloud storage anyway (1TB Google One is included)
• You want the largest context window in the industry

❌ You SHOULDN’T Pay If…

• You write for a living (get Claude Pro instead)
• You code professionally (get DeepSeek V3 free + GitHub Copilot)
• You don’t use Google products (Gemini’s integration is its main advantage)
• You’re on a tight budget (Claude Free + ChatGPT Free cover 90% of use cases)

How to Get Gemini Advanced for Less in 2025

1. Use the 2-Month Free Trial

Google offers a 2-month free trial of Gemini Advanced for new users. Use it to thoroughly test whether the 1M context window matters for your workflow.

2. Annual Plan Discount

Google One with Gemini Advanced is cheaper if you pay annually. $199.99/year vs $239.88/year — saves $40.

3. Student Discount (Occasional)

Google occasionally runs student campaigns (.edu email). Check gemini.google.com — the banner appears when logged in with a school account.

FAQ: Google Gemini 1.5 Pro Review 2025

Final Verdict: Is Gemini Advanced Worth $19.99/Month in 2025?

For Google Workspace users and researchers with massive documents: Absolutely. The 1M token context window alone justifies the cost if you regularly work with large files. The included 1TB Google One storage makes it a great value.

For writers and general users: No. Get Claude 3.5 Sonnet Pro ($20/month) for better writing, or stick with ChatGPT Free + Claude Free — both are capable enough for most people.

Best approach: Start with the 2-month free trial. If you don’t use the 1M context window at least once a week, cancel before the trial ends. If you do use it, the $19.99/month is easy to justify.

7 Best DeepSeek V3 Alternatives in 2025 (Compared & Ranked)

Updated April 2025 · 11 min read · Covers DeepSeek V3 vs top competitors

DeepSeek V3 shook the AI world in early 2025 — open-weight, GPT-4-level coding, and free to use. But it has queue times during peak hours, and the web interface is basic compared to Claude or ChatGPT.

We tested 7 top DeepSeek alternatives across coding ability, math, price, and self-hosting options. Here’s the complete ranking for 2025.

Quick Comparison Table

1. Claude 3.5 Sonnet — Best Overall Alternative

Free: 50 messages/day · Paid: $20/mo Pro · Context: 200K tokens

Claude 3.5 Sonnet is the best alternative to DeepSeek V3 if you’re willing to pay. It outperforms DeepSeek on writing quality, safety, and long-document processing. The “Artifacts” feature (real-time code/document rendering) is unique.

Why Claude beats DeepSeek

• Writing quality: Noticeably better for emails, blogs, and reports
• Artifacts: See code, SVGs, and documents render live
• Free tier: 50 messages/day is generous (no queue)
• Safety: Least likely to refuse benign prompts

Best for: Writers, researchers, and anyone who wants the best AI writing in 2025.

2. ChatGPT (GPT-4o) — Best Free Alternative

Free: limited GPT-4o access · Paid: $20/mo Plus · Context: 128K tokens

ChatGPT Free now includes limited GPT-4o access — something that didn’t exist in 2023-2024. If DeepSeek’s queue times frustrate you, ChatGPT Free is the answer. The Plus plan adds plugins, DALL-E 3, and web browsing.

Why choose ChatGPT over DeepSeek

• Plugin ecosystem: 1,000+ extensions for every use case
• Multimodal: Handles images, voice, and file uploads
• DALL-E 3: Built-in image generation (DeepSeek has none)
• No queues: Paid tier has zero wait time, ever

Free: 15 requests/min · Paid: $19.99/mo Advanced · Context: 1M tokens

Best for: Researchers and developers with massive document/code repositories.

4. GitHub Copilot — Best for Coding in IDE

Free: students + open-source · Paid: $10/mo · Context: Varies by model

If you primarily use DeepSeek for coding, GitHub Copilot is better integrated into your workflow. It works inside VS Code, JetBrains, and Neovim with real-time code completion (not just chat). The 2025 update added Claude 3.5 Sonnet as a model option.

Best for: Developers who want AI assistance inside their IDE, not in a separate chat window.

5. Qwen 2.5 Coder — Best Open-Source Coding Alternative

Free: open-weight · Paid: API ~¥0.02/1M tokens · Context: 128K

Qwen 2.5 Coder (Alibaba) is the strongest open-weight coding model in 2025. It outperforms DeepSeek V3 on some Chinese-language coding benchmarks and is fully open-weight for self-hosting.

Best for: Developers who want an open-weight coding model with strong Chinese + English support.

6. Llama 3.1 (Meta) — Best for Self-Hosting

Free: open-weight · Paid: Free (self-host) · Context: 128K (Llama 3.1 405B)

Llama 3.1 405B is Meta’s answer to GPT-4. It’s fully open-weight, meaning you can download and run it on your own hardware for complete privacy. If DeepSeek’s servers being in China is a concern, Llama 3.1 is the answer.

Best for: Privacy-conscious users and companies who want to self-host.

7. Mistral Large 2 — Best European / Privacy-Focused

Free: Le Chat (limited) · Paid: ~€0.008 per 1K tokens (API) · Context: 128K

Mistral Large 2 is Europe’s answer to GPT-4. It’s open-weight, privacy-focused (based in France), and the API pricing is ~1/10th of GPT-4o. If you’re in Europe and data sovereignty matters, this is your best bet.

Best for: European users and privacy-conscious developers.
