DeepSeek is a leading Chinese artificial intelligence research firm based in Hangzhou. Backed by High-Flyer Quant, DeepSeek shocked the global tech community by releasing foundation models that match or exceed the performance of OpenAI's GPT-4 and Anthropic's Claude in key reasoning and coding benchmarks, but at a fraction of the cost.
Its flagship model, DeepSeek-R1, uses advanced reinforcement learning to perform multi-step "reasoning" (similar to OpenAI's o1 series), showing its full chain of thought while arriving at an answer. DeepSeek's API pricing is disruptively cheap, running at up to 95% cheaper than Western frontier models, which has led to massive adoption among global developers and startups.
DeepSeek is fully open-weights, meaning its model architectures and parameters are publicly accessible under open licenses, allowing organizations to self-host and customize the models on their own local servers.
