How Are DeepSeek's Costs Calculated?

DeepSeek has sent shockwaves through the global AI community. Recently, Elon Musk showcased "the smartest AI on Earth"—Gork3—during a live stream, claiming its reasoning capabilities surpass all known models, including DeepSeek-R1 and OpenAI's o1. Meanwhile, WeChat announced its integration with DeepSeek-R1, signaling a potential seismic shift in AI-powered search.

Microsoft, NVIDIA, Huawei Cloud, Tencent Cloud, and other tech giants have already adopted DeepSeek. Users have even developed creative applications like fortune-telling and lottery predictions, fueling its valuation to an estimated $100 billion.

What sets DeepSeek apart is its cost efficiency: it trained the DeepSeek-R1 model—a rival to OpenAI's o1—for just $5.576 million in GPU expenses. In contrast, Gork3 reportedly consumed 200,000 NVIDIA GPUs (each costing around $30,000), while DeepSeek used only about 10,000.

Even more astonishingly, Fei-Fei Li's team recently claimed to train a reasoning model, S1, for under $50 in cloud computing costs, though its parameter scale is smaller than DeepSeek-R1's. This raises critical questions: How strong is DeepSeek really? Why are competitors racing to match or surpass it? And what exactly goes into training a large AI model?

Understanding DeepSeek's Capabilities

1. Beyond DeepSeek-R1: A Multi-Model Ecosystem

While DeepSeek-R1 garners attention, it’s just one of several models in DeepSeek’s arsenal:

• General-Purpose Models (e.g., DeepSeek-V3)

  • Optimized for tasks like summarization, translation, and Q&A.
  • Faster responses, relying on probabilistic predictions from vast datasets.

• Reasoning Models (e.g., DeepSeek-R1)

  • Excel at complex tasks like math problems and coding challenges.
  • Slower, methodical responses using chain-of-thought reasoning.

2. Performance Benchmarks

Reasoning Models (Top Tier):

• OpenAI’s o-series (e.g., o3-mini)
• Google’s Gemini 2.0
• DeepSeek-R1
• Alibaba’s QwQ

General-Purpose Models (Top Tier):

• Google’s Gemini (closed-source)
• OpenAI’s ChatGPT
• Anthropic’s Claude
• DeepSeek-V3
• Alibaba’s Qwen

Experts note that while DeepSeek-R1 narrows the gap with OpenAI’s o3-mini, the latter still holds a slight edge. However, DeepSeek’s cost-to-performance ratio is unmatched.

Breaking Down AI Training Costs

Training a large model involves three key expenses:

1. Hardware

   • Option A: Purchase GPUs (high upfront cost, low long-term).
   • Option B: Rent cloud GPUs (recurring expense).
   • DeepSeek used just 2,048 NVIDIA GPUs for DeepSeek-V3, compared to OpenAI’s tens of thousands.

2. Data

   • Curating high-quality datasets (e.g., buying pre-processed data vs. manual scraping).
   • DeepSeek employed FP8 low-precision training, accelerating speed while reducing memory demands.

3. Labor & Iterations

   • Hidden costs: Research, architecture tweaks, and failed experiments.
   • SemiAnalysis estimates DeepSeek’s total 4-year cost at ~$2.57B—far below competitors’ $10B+ investments.

DeepSeek’s Cost-Saving Innovations

1. Ultra-Efficient MoE Architecture

• Fine-grained expert segmentation minimizes redundancy.
• Achieves LLaMA2-7B-level performance with 40% less computation.

2. Algorithmic Optimizations

• GRPO > PPO: Eliminates the need for a separate value model, slashing compute needs.
• MLA over MHA: Reduces memory usage, lowering API costs (e.g., $1 per million input tokens).

3. Flexible Training Approaches

• Proved reasoning models can succeed via:

  • Pure reinforcement learning (DeepSeek-R1-zero).
  • Pure supervised fine-tuning (distilled models).
• Challenges the industry’s reliance on hybrid methods.

The Future: Cheaper, Faster, Smarter

Cost reductions are accelerating:

• Training costs drop ~75% annually (ARK Invest).
• Inference costs plummet 85–90% yearly.
• Small models now match GPT-3’s performance at 1/1200th the cost (per Anthropic’s CEO).
