DeepSeek’s new AI model appears to be one of the best ‘open’ challengers yet

A Chinese lab has created what appears to be one of the most powerful “open” AI models to date.

The model, DeepSeek V3, was developed by the AI firm DeepSeek and was released on Wednesday under a permissive license that allows developers to download and modify it for most applications, including commercial ones.

DeepSeek V3 can handle a range of text-based workloads and tasks, like coding, translating, and writing essays and emails from a descriptive prompt.

According to DeepSeek’s internal benchmark testing, DeepSeek V3 outperforms both downloadable, “openly” available models and “closed” AI models that can only be accessed through an API. In a subset of coding competitions hosted on Codeforces, a platform for programming contests, DeepSeek outperforms other models, including Meta’s Llama 3.1 405B, OpenAI’s GPT-4o, and Alibaba’s Qwen 2.5 72B.

DeepSeek V3 also crushes the competition on Aider Polyglot, a test designed to measure, among other things, whether a model can successfully write new code that integrates into existing code.

DeepSeek claims that DeepSeek V3 was trained on a dataset of 14.8 trillion tokens. In data science, tokens are used to represent bits of raw data — 1 million tokens is equal to about 750,000 words.

It’s not just the training set that’s massive. DeepSeek V3 is enormous in size: 685 billion parameters. (Parameters are the internal variables models use to make predictions or decisions.) That’s around 1.6 times the size of Llama 3.1 405B, which has 405 billion parameters.

Parameter count often (but not always) correlates with skill; models with more parameters tend to outperform models with fewer parameters. But large models also require beefier hardware in order to run. An unoptimized version of DeepSeek V3 would need a bank of high-end GPUs to answer questions at reasonable speeds.

While it’s not the most practical model, DeepSeek V3 is an achievement in some respects. DeepSeek was able to train the model using a data center of Nvidia H800 GPUs in just around two months — GPUs that Chinese companies were recently restricted by the U.S. Department of Commerce from procuring. The company also claims it only spent $5.5 million to train DeepSeek V3, a fraction of the development cost of models like OpenAI’s GPT-4.

The downside is that the model’s political views are a bit filtered. Ask DeepSeek V3 about Tiananmen Square, for instance, and it won’t answer.

DeepSeek, being a Chinese company, is subject to benchmarking by China’s internet regulator to ensure its models’ responses “embody core socialist values.” Many Chinese AI systems decline to respond to topics that might raise the ire of regulators, like speculation about the Xi Jinping regime.

DeepSeek, which recently unveiled DeepSeek-R1, an answer to OpenAI’s o1 “reasoning” model, is a curious organization. It’s backed by High-Flyer Capital Management, a Chinese quantitative hedge fund that uses AI to inform its trading decisions.

DeepSeek’s models have forced competitors like ByteDance, Baidu, and Alibaba to cut the usage prices for some of their models — and make others completely free.

High-Flyer builds its own server clusters for model training, one of the most recent of which reportedly has 10,000 Nvidia A100 GPUs and cost 1 billion yen (~$138 million). Founded by Liang Wenfeng, a computer science graduate, High-Flyer aims to achieve “superintelligent” AI through its DeepSeek org.

In an interview earlier this year, Liang described open sourcing as a “cultural act,” and characterized closed source AI like OpenAI’s a “temporary” moat. “Even OpenAI’s closed-source approach hasn’t stopped others from catching up,” he noted.

Indeed.
