Generative AI Showdown 2025: DeepSeek vs. ChatGPT vs. Gemini vs. Perplexity vs. Copilot
Architecture & Efficiency
1. DeepSeek-R1 (China)
- Framework: Mixture-of-Experts (MoE) with 671B parameters (37B active per query), optimized for cost efficiency ($5.5M training cost) :cite[2]:cite[6].
- Strengths: Excels in mathematical reasoning (95% GSM8K accuracy) and Chinese NLP tasks; ideal for technical problem-solving and private deployment :cite[1]:cite[3].
- Limitations: Weak in English-language tasks and multimodal generation :cite[1].
2. ChatGPT-4o (OpenAI)
- Framework: Dense Transformer (1.8T parameters), optimized for creative writing and multilingual support (96 languages) :cite[1]:cite[4].
- Strengths: Dominates conversational AI and code generation; integrates DALL·E for image synthesis :cite[2]:cite[9].
- Limitations: High API costs ($30/million tokens) and occasional factual hallucinations :cite[2]:cite[6].
3. Gemini 2.0 (Google)
- Framework: Multimodal architecture supporting text, images, audio, and video with a 2M-token context window :cite[5]:cite[8].
- Strengths: Real-time Google Search integration, native video generation, and autonomous task execution (e.g., research automation) :cite[4]:cite[9].
- Limitations: Struggles with temporal accuracy (e.g., timeline errors) and complex math problems :cite[6]:cite[8].
4. Perplexity
- Framework: Hybrid LLM with real-time web search APIs :cite[4]:cite[6].
- Strengths: Free tier (600 daily queries), rigorous source citation for academic research :cite[6].
- Limitations: Limited generative depth and coding capabilities :cite[4].
5. GitHub Copilot
- Framework: GPT-4-based code assistant integrated with IDEs :cite[4].
- Strengths: Real-time code suggestions (70+ languages) and debugging support :cite[2]:cite[6].
- Limitations: "Lazy" placeholder code generation and limited context retention :cite[2].
