What is DeepSeek?
DeepSeek is an AI company founded in Hangzhou, China in 2023. Their V3 model released in late 2024 and R1 reasoning model in January 2025 achieved benchmark scores comparable to GPT-4o and Claude 3.5, while reportedly being trained at 1/30th the cost.
Performance Comparison
Coding Tasks
DeepSeek R1 actually outperforms ChatGPT on several coding benchmarks (HumanEval, SWE-bench). Many developers report being impressed by DeepSeek’s code generation quality.
Reasoning
DeepSeek R1’s chain-of-thought reasoning is impressive. It shows its work step-by-step, similar to OpenAI’s o1 model. This makes it particularly strong for math and logical problems.
Writing Quality
ChatGPT (especially with GPT-4o) produces more natural, nuanced English text. DeepSeek’s output can sometimes feel slightly more mechanical or translated.
⚠️ The Privacy Concern
DeepSeek is a Chinese company subject to Chinese data laws. This raises legitimate concerns for:
- Enterprise users with sensitive data
- Government and defense contractors
- Healthcare and legal professionals
- Anyone in privacy-sensitive industries
For personal use and non-sensitive projects, this may be acceptable. For business use, verify your organization’s data policy.
When to Use DeepSeek vs ChatGPT
- Use DeepSeek for: Personal coding projects, math problems, cost-sensitive API applications, open-source development
- Use ChatGPT for: Business use, sensitive data, best English writing quality, broadest feature set
Is DeepSeek safe to use?
DeepSeek is technically safe for most personal use cases. However, as a Chinese company, it’s subject to Chinese data regulations. Avoid sharing sensitive personal information, confidential business data, or proprietary code. For enterprise use, consult your legal and IT teams first.
Is DeepSeek really better than ChatGPT?
DeepSeek R1 matches or exceeds GPT-4o on specific benchmarks (coding, math) while being significantly cheaper to use via API. For general English writing and most consumer use cases, ChatGPT remains slightly better. The cost-performance ratio is where DeepSeek truly excels.
