Two more voices joined the choir on Tuesday. Alphabet, the parent company of search engine Google, only had good things to say about DeepSeek when it reported mixed results. “Tremendous,” and “very good work” is how CEO Sundar Pichai described the upstart, which claims to have developed an AI model that rivals those made by U.S. tech companies at a fraction of the cost. Pichai added that Google’s models are still some of the best.
