What Is DeepSeek?
DeepSeek is an AI chatbot and model developer created by a Chinese AI lab that grew out of a quantitative hedge fund called High-Flyer. It became widely known for building powerful AI models at a much lower cost than most competitors, then releasing those models as open-weight — meaning anyone can download, inspect, or even run the model themselves, instead of only accessing it through DeepSeek’s own app or website.
Key Points:
- Free to use on the web and through its app
- API access is significantly cheaper than most major competitors
- Models are open-weight, allowing self-hosting for full control
- Especially popular with developers, researchers, and technical teams
- Known for strong coding and reasoning performance at a low cost
What Is ChatGPT?
ChatGPT is an AI chatbot built by OpenAI, and it’s the most widely used AI assistant in the world, with hundreds of millions of people using it every week. Unlike DeepSeek’s more technical, developer-focused approach, ChatGPT is built as a complete, polished product for everyday use.
Key Points:
- Helps with writing, coding, research, image generation, and more
- Offers a free version with limited daily use
- Paid plans unlock full access plus extra tools like data analysis and deep research.
- Includes image and video generation capabilities
- Offers enterprise-level plans for businesses needing security and collaboration features

DeepSeek vs ChatGPT: Pricing Comparison
Pricing is where DeepSeek and ChatGPT differ the most dramatically — and it’s often the deciding factor for developers, businesses, and heavy users choosing between the two. Here’s a breakdown of the pricing comparison of DeepSeek and ChatGPT:
DeepSeek Pricing
DeepSeek keeps things simple and affordable, whether you’re a casual user or a developer building at scale.
| Plan Type | Cost |
|---|---|
| Web/App (Standard Use) | Free, no subscription required |
| API — Lighter Model | Around $0.14 per million input tokens, $0.28 per million output tokens |
| API — Higher-Performance Model | Around $0.44–$1.74 per million input tokens, $0.87–$3.48 per million output tokens (promotional pricing may apply) |
| Self-Hosted (Open-Weight) | Free — no ongoing API costs at all |
Key Points:
- No subscription needed for regular use on the web or app
- API pricing is dramatically lower than ChatGPT’s, especially on output tokens
- Open-weight models let businesses self-host for free, avoiding API costs entirely
- A strong option for cost-conscious developers and privacy-focused businesses
ChatGPT Pricing
ChatGPT follows a more traditional subscription model, with pricing that reflects its polished, all-in-one experience.
| Plan Type | Cost |
|---|---|
| Free Tier | Free, limited to a small number of messages every few hours |
| ChatGPT Plus | $20/month for individuals |
| Business/Enterprise | Higher pricing, based on team size and features |
| API Access | Around $5 per million input tokens, $30 per million output tokens |
Key Points:
- Free tier is usable but limited by message count within a set time window
- Plus plan unlocks full access plus tools like data analysis and deep research
- Business and enterprise plans add stronger security and collaboration features
- API pricing is significantly higher than DeepSeek’s, reflecting its broader feature set and infrastructure
DeepSeek vs ChatGPT: Feature Comparison
Pricing tells you what each platform costs, but it doesn’t tell you what you can actually do with them — and that’s where DeepSeek and ChatGPT diverge just as sharply. One is built as a lean, developer-first model focused on raw reasoning and coding power; the other is built as a full productivity assistant wrapped around that core model. Here’s a breakdown of what each platform actually offers.
DeepSeek: Key Features
Strong Coding and Reasoning Performance
DeepSeek V4 Pro performs competitively with — and on several coding benchmarks, matches or slightly exceeds — leading ChatGPT models, particularly on tasks like SWE-Bench and HumanEval.
Thinking and Non-Thinking Modes
DeepSeek V4 offers distinct reasoning modes, letting the model switch between fast responses and deeper, step-by-step reasoning for harder, multi-step problems.
Large Context Window
Supports up to roughly 1 million tokens of context, consistent across use cases, making it well-suited for handling long documents or extended conversations.
Open-Weight, Self-Hostable Models
DeepSeek’s models are released under an open license, meaning businesses can download and run them on their own infrastructure — avoiding ongoing API costs entirely and keeping full control over data and deployment.
PI-First, Minimal Ecosystem
DeepSeek is mainly made for developers. It works well through its API, but it does not have as many built-in tools and features as ChatGPT. To get a bigger app-like experience, people often use it with other platforms.
Limited multimodal support
DeepSeek is mostly strong at text, coding, and reasoning. ChatGPT is better built for working with text, images, voice, and video in one place.
China-Based Hosting
DeepSeek mainly uses servers in China. This may matter for companies that need their data stored in a certain country.
ChatGPT: Key Features
Full Multimodal Capabilities
ChatGPT supports native image generation, voice mode, and video-related tools, offering a genuinely rounded experience across text, image, and audio — an area where it holds a clear advantage.
Strong Agentic Coding and Tool Use
While DeepSeek is competitive on raw coding benchmarks, ChatGPT pulls ahead in agentic coding — using tools, executing multi-step workflows, and handling tasks like computer use, backed by tighter ecosystem integration.
Large Context Window
ChatGPT also supports roughly 1 million tokens of context in its main product, though its Codex tool offers a more limited 400,000-token window specifically for coding sessions.
Rich Built-In Ecosystem
ChatGPT includes Custom GPTs (build your own specialized assistant), Canvas (a collaborative writing/coding workspace), Deep Research, web browsing, and a mature plugin/integration layer connecting to many external apps — all built directly into the product.
Closed, Proprietary Model
ChatGPT is a closed system, accessible only through OpenAI’s own platforms and API. There’s no self-hosting option, which trades off flexibility for a more managed, consistent experience.
Enterprise-Ready Features
ChatGPT’s business tier offers stronger security controls, team collaboration tools, and formal data-residency commitments aimed at enterprise compliance needs.
U.S.-Based Hosting
Data is primarily processed on servers in the United States, which may matter for businesses with specific regional compliance requirements.
DeepSeek vs ChatGPT: Which One Should You Choose?
Both DeepSeek and ChatGPT can help businesses save time, improve productivity, automate repetitive work, and support better decision-making. Businesses across many industries are already using these tools for a range of purposes:

PakarPBN
A Private Blog Network (PBN) is a collection of websites that are controlled by a single individual or organization and used primarily to build backlinks to a “money site” in order to influence its ranking in search engines such as Google. The core idea behind a PBN is based on the importance of backlinks in Google’s ranking algorithm. Since Google views backlinks as signals of authority and trust, some website owners attempt to artificially create these signals through a controlled network of sites.
In a typical PBN setup, the owner acquires expired or aged domains that already have existing authority, backlinks, and history. These domains are rebuilt with new content and hosted separately, often using different IP addresses, hosting providers, themes, and ownership details to make them appear unrelated. Within the content published on these sites, links are strategically placed that point to the main website the owner wants to rank higher. By doing this, the owner attempts to pass link equity (also known as “link juice”) from the PBN sites to the target website.
The purpose of a PBN is to give the impression that the target website is naturally earning links from multiple independent sources. If done effectively, this can temporarily improve keyword rankings, increase organic visibility, and drive more traffic from search results.
