What Is DeepSeek? Origins and Evolution

DeepSeek AI, founded in 2023 by a team of researchers backed by High-Flyer Quant Fund, emerged from China’s vibrant AI scene with a mission to democratize advanced language models. The company’s name reflects its focus on “deep seeking” through data and reasoning, aiming to unravel AGI mysteries with curiosity and long-termism. DeepSeek’s journey began with DeepSeek-V1, but it gained global traction with DeepSeek-V2 in mid-2024, a 236-billion-parameter model trained on modest hardware yet rivaling top-tier Western AIs.

By 2025, DeepSeek has evolved rapidly. The release of DeepSeek-V3 in early 2025 introduced a hybrid inference structure with “Think” and “Non-Think” modes, enhancing reasoning speed and agent capabilities. DeepSeek-R1, launched shortly after, incorporated chain-of-thought reasoning for step-by-step problem-solving, making it ideal for complex queries. Unlike proprietary models, DeepSeek’s open-source nature—licensed under MIT—allows developers to fine-tune, run locally, or integrate freely, fostering a thriving community on platforms like Hugging Face.

DeepSeek’s development philosophy prioritizes efficiency. Trained on 8.1 trillion tokens using a Mixture-of-Experts (MoE) architecture, it activates only relevant “experts” for tasks, reducing computational demands. This approach enabled training costs of just $5.58 million for R1—far below Western counterparts. As of August 2025, DeepSeek boasts over 100 million users, with strong adoption in Asia and growing interest globally for its multilingual prowess, especially in English and Chinese.

What Is ChatGPT? The Benchmark of Conversational AI

ChatGPT, developed by OpenAI, revolutionized AI accessibility upon its 2022 launch. Starting as a simple chatbot based on GPT-3.5, it evolved into a multimodal powerhouse with GPT-4o by 2024, incorporating voice, image, and video capabilities. OpenAI’s mission—to advance AGI safely—drives ChatGPT’s iterative improvements, with over 400 million active users worldwide as of 2025.

ChatGPT’s evolution includes key milestones: GPT-4 in 2023 for enhanced reasoning, GPT-4o in 2024 for real-time interactions, and o1-series models in 2025 for advanced problem-solving. Unlike DeepSeek, ChatGPT operates on a transformer-based architecture reinforced with human feedback (RLHF), ensuring more natural, safe responses. It’s integrated into ecosystems like Microsoft Copilot and Apple Intelligence, expanding its reach.

In 2025, ChatGPT offers tiers: a free version with GPT-4o mini, Plus ($20/month) for expanded features like Sora video generation, and Pro ($200/month) for unlimited advanced modes. Its strength lies in versatility—handling everything from casual chats to enterprise workflows—backed by robust safety measures and continuous updates.

Technical Architecture: MoE vs. Transformers

At their core, both models process language through neural networks, but their architectures differ significantly.

DeepSeek employs a Mixture-of-Experts (MoE) system, where a “gating network” routes queries to specialized sub-networks. This efficiency allows DeepSeek-V3 (with 562 billion parameters) to outperform denser models while using less power. Benchmarks show DeepSeek-V2 scoring 81.1% on HumanEval (coding) and 90% on MATH, often edging out GPT-4o in technical tasks. However, MoE can lead to inconsistencies in creative outputs.

ChatGPT’s transformer architecture, enhanced by RLHF, excels in coherent, context-aware responses. GPT-4o achieves 88.7% on MMLU (general knowledge) and 76.4% on average benchmarks, surpassing DeepSeek in versatility. Yet, it’s computationally intensive, contributing to higher costs.

In head-to-head tests, DeepSeek processes tokens faster (up to 60/second) than GPT-4o’s 30-50, but ChatGPT handles multimodal inputs better. For instance, DeepSeek lacks native image generation, relying on text descriptions, while ChatGPT integrates DALL·E 3 seamlessly.

Key Features and Capabilities

DeepSeek shines in coding and math. Its DeepSeek-Coder-V2 beats GPT-4o in programming benchmarks (75.3% average), generating frontend/backend code with database schemas in one prompt. For math, it achieves 90% accuracy on problems, ideal for STEM users.

ChatGPT counters with multimodal features: image analysis, voice mode, and Sora for videos. It excels in creative writing, producing polished narratives with emotional depth. In tests, ChatGPT’s sci-fi stories flow cinematically, while DeepSeek’s are logical but less evocative.

Both support web search, but ChatGPT’s “Deep Research” provides cited, real-time insights. DeepSeek’s “DeepThink (R1)” mode offers chain-of-thought reasoning, useful for logic puzzles, though slower.

In multilingual tasks, DeepSeek handles English/Chinese flawlessly, with robust support for 100+ languages. ChatGPT is strong globally but occasionally biases toward English.

Integration and Accessibility

DeepSeek’s open-source status enables local runs on high-end hardware (e.g., 8GB RAM minimum) or API integration at $0.14/million input tokens—96% cheaper than ChatGPT’s $2.50/million for GPT-4o. It’s free on web/mobile, with no limits, appealing to startups.

ChatGPT integrates via API into apps like Slack or custom GPTs, but requires subscriptions for full access. Its ecosystem includes plugins for tools like Adobe, enhancing productivity. However, free users face caps, unlike DeepSeek’s unrestricted model.

Real-World Applications and Use Cases

DeepSeek thrives in development: Coders use it for rapid prototyping, with users reporting it solves PHP/.NET issues better than ChatGPT. In education, it generates math explanations with step-by-step reasoning. Businesses leverage its low-cost API for analytics, processing datasets efficiently.
