DeepSeek just gave away an AI model that rivals GPT-5 – and it could change everything

• Chinese startup DeepSeek released two powerful new AI models that rival GPT-5 and Gemini 3 Pro
• The models are open source, cheap to run, and designed for real-world reasoning with built-in tool use
• Their release challenges U.S. tech dominance and reignites global AI competition

Chinese startup DeepSeek has casually lobbed two new enormous AI models into the already smoldering international arms race: DeepSeek-V3.2, a model built for everyday reasoning, and DeepSeek-V3.2-Speciale, a high-octane variant that allegedly outperformed top American models in elite math and coding competitions. Not only that, but they released them under an open-source license.

What makes this move notable isn’t just the models and their capabilities, but also how they were released. American firms like OpenAI and Google rely on powerful, and often expensive, models relying on private APIs and red-team testing for the most cutting-edge models. DeepSeek has weaponized openness.

DeepSeek-V3.2 reportedly matches or beats GPT-5 and Gemini 3 Pro on long-form reasoning, tool use, and dense problem solving, including competitions like the International Mathematical Olympiad and the ICPC World Finals. The “Speciale” version scored 99.2% on the Harvard-MIT Math Tournament, 73% on software bug fixing, and posted gold-medal results on multiple international benchmarks even without internet access or external tools.

The trick behind this performance is a clever architectural hack called DeepSeek Sparse Attention, or DSA. Traditional transformer models become computationally bloated as context length increases, and they have to consider every word in a document relative to every other word. DSA reduces costs by focusing only on the most relevant parts of the input, essentially skimming rather than reading every word. That alone slashes costs for long documents by up to 70%, making the model relatively cheap.

This matters to real people because cost is everything in AI deployment. Most frontier models today are trapped behind paywalls and throttled access. But DeepSeek’s latest models and their 128,000-token context windows are free to download and modify. A solo developer or student team can tinker with systems that just a few months ago would’ve required a lab and a huge cloud budget.

DeepSeek’s “thinking in tool-use” breakthrough is especially notable. Most AI agents struggle to juggle multiple tools because each action resets their internal reasoning. DeepSeek fixed that by preserving memory across tools. The company trained the model using over 85,000 complex synthetic instructions to make it work with tools like real web browsers and coding environments.

That’s a level of real-world task preparation that most current chatbots simply aren’t built for. It’s one thing to summarize a recipe. It’s another thing to plan a multi-day vacation under a strict budget with interdependent lodging and food constraints and to do it while testing code snippets and checking exchange rates.

International AI rivalry

The license setup might be even more disruptive. By using the MIT open-source license, DeepSeek has made it legally possible for anyone to copy, remix, or commercialize its models. That flies directly in the face of the current trend of protecting model weights as intellectual property, citing safety, misuse risk, and corporate secrecy.

Openness doesn't mean transparency, however. That's why German regulators have tried to block DeepSeek over data transfer concerns. Italy banned the app earlier this year, and U.S. lawmakers want it off government devices entirely. DeepSeek is a Chinese company, and the geopolitical context looms large. But suppose DeepSeek’s models really do deliver frontier performance at a fraction of the cost, and you don’t mind the geopolitical baggage. What exactly are the American firms offering that’s worth the markup?

For now, DeepSeek’s Speciale variant is only available via a temporary API. But by mid-December, it will be merged into the broader V3.2 release and accessible to everyone. If the last few years were defined by ChatGPT’s friendly intro to AI, this release feels like a stark reminder: the gloves are off, and the global AI race isn’t just about features anymore, it’s about access, cost, and control.
