DeepSeek, an AI company known for its transparency in exposing its chain of thought, is considered a success for providing a free reasoning model that rivals OpenAI's pricier alternatives. Conversely, Inflection, another AI company, failed to take off due to factors including tough competition, a commoditized product, and inadequate design that didn't interactively communicate the chatbot capabilities, leaving users to learn via trial and error.
An under appreciated aspect of the Deepseek stuff is the decision to make the AI “thought” process transparent.
