The DeepSeek team even held an "Open-Source Week" last month, which saw it release more technical details about the development of its R1 model.
While DeepSeek's model itself is free, the start-up charges for Application Programming Interface, which enables the integration of AI models and their capabilities into other companies' applications. However, its API charges are advertised to be far cheaper compared with OpenAI and Anthropic's latest offerings.
OpenAI and Anthropic also generate revenue by charging individual users and enterprises to access some of their models. These models are considered to be 'closed-source,' as their datasets, and algorithms are not open for public access.
