What Is ChatGPT?

ChatGPT, built by OpenAI, is a conversational assistant powered by the GPT-4 family. It’s known for its writing fluency, helpful tone, and support across multiple industries — from marketing and sales to customer service and coding.

‍

Standout Features:

• Natural conversation and storytelling
• Code generation and debugging help
• Custom instructions and memory (for Plus users)
• Team features like folders, permissions, and shared prompts (ChatGPT Team)

What Is DeepSeek AI?

DeepSeek is a newer entrant but one that’s shaking things up — especially among developers and researchers. It’s known for its technical reasoning, math problem-solving, and performance on coding benchmarks.

🧪 Fun fact: DeepSeek-Coder scored higher than GPT-4 on some coding benchmarks — including HumanEval and MBPP.

‍

What Makes DeepSeek Stand Out:

• Focused on logic-heavy tasks (e.g., solving Leetcode problems)
• Supports multiple programming languages
• Often open-source and free
• Runs locally or in lightweight environments

✍️ Writing & Content Creation

ChatGPT is the undisputed leader here. Its tone is flexible — you can have it write a Shakespearean sonnet, a press release, or a casual tweet with just a few words of instruction.

DeepSeek, on the other hand, can produce text — but it’s not optimized for creative or nuanced writing.

✔️ Best for writing: ChatGPT
❌ Not ideal for writing: DeepSeek
