DeepSeek V4 vs GPT-5.4 vs Claude 4.6 vs Gemini 3.1 Pro — side by side
🏆 DeepSeek Advantages
Far Cheaper Than All Competitors
V4-Pro API at $0.435/$0.87 per M tokens is roughly 5-15x cheaper than GPT-5.4 ($2.50/$15), 10-30x cheaper than Claude 4.6 ($5/$25), and 5-14x cheaper than Gemini 3.1 ($2/$12). V4-Flash is cheaper still at $0.14/$0.28.
Leading Open-Model Coding
V4 scores 80.6% on SWE-bench Verified — the highest among open models, tied with Gemini 3.1 (80.6%) and ahead of GPT-5.4 (77.2%). LiveCodeBench Pass@1 93.5, Codeforces 3206.
Fully Open Source (MIT)
Unlike GPT-5.4, Claude 4.6 and Gemini 3.1 (all closed-source), DeepSeek is fully open under MIT. Self-host for free, full data control, no vendor lock-in.
Low-Cost 1M Context (CSA+HCA)
V4's CSA+HCA hybrid attention serves a full 1M-token context at ~27% of V3.2 per-token compute and ~10% of its KV-cache memory — affordable ultra-long context.
Native Chinese Optimization
Industry-leading Chinese understanding and generation, outperforming all western models in Chinese tasks.
🎖 Competitor Advantages
GPT-5.4: Computer Control
GPT-5.4 features native computer control capability, can interact with desktop applications. Strongest general-purpose AI with mature ecosystem.
Claude 4.6: Best Coding & Safety
Claude 4.6 leads SWE-bench at 80.8%, excels in long-context reliability (76% MRCR v2 at 1M), and has industry-leading safety alignment.
Gemini 3.1: Reasoning & Speed
Gemini 3.1 Pro scores 77.1% on ARC-AGI-2 and 94.3% on GPQA Diamond. Output at 114.8 tokens/s — fastest among frontier models.
Ecosystem & Support
OpenAI, Anthropic and Google all have mature developer ecosystems, extensive documentation, enterprise support, and deep IDE integrations.

Can DeepSeek replace ChatGPT, Claude, or Gemini?
For most scenarios, yes! DeepSeek V4 scores 80.6% on SWE-bench Verified (just shy of Claude 4.6's 80.8%, tied with Gemini 3.1), at roughly 5-30x lower cost. For general chat, GPT-5.4 is slightly stronger. For coding, Claude 4.6 and DeepSeek V4 lead. Key advantage: DeepSeek is open-source (MIT).
Why is DeepSeek so much cheaper than GPT-5.4, Claude 4.6, and Gemini 3.1?
1) Open-source (MIT) model reduces overhead; 2) Efficient MoE architecture (V4-Pro 1.6T total, 49B active); 3) CSA+HCA hybrid attention cuts 1M-context compute to ~27% and KV-cache memory to ~10% of V3.2; 4) No closed-source profit margins. Result: $0.435/$0.87 per M (Pro) vs $2-$25/M for competitors.
Is DeepSeek safe?
Very safe! Open-source code is auditable — unlike closed models from OpenAI, Anthropic, and Google. Enterprises can self-host with zero data leakage. Using on Atlas Cloud provides SOC I & II, HIPAA certification.
How to choose between DeepSeek, GPT-5.4, Claude 4.6, and Gemini 3.1?
Budget-conscious→DeepSeek (5-30x cheaper); Coding→DeepSeek V4 or Claude 4.6; Data privacy→DeepSeek (self-host); Chinese tasks→DeepSeek; Computer control→GPT-5.4; Fastest inference→Gemini 3.1 (114.8 t/s); General chat→GPT-5.4.
Can I use DeepSeek with VS Code, Cursor, or Continue.dev?
Yes! DeepSeek is fully compatible with all major AI coding IDEs via API key. OpenAI-compatible format means zero migration from GPT — just change the endpoint and model name.
