Amazon unveiled a new series of AI models called Nova this week. Amazon believes AI models are not in a winner-take-all market. Google has a leading AI model in Gemini, but also provides access to other models through its Vertex cloud service, and Microsoft has a similar offering. As a result, Anthropic, which Menlo Ventures has backed, doubled its share in the AI model market to 24% this year, while OpenAI's share dropped from 50% to 34% year-over-year, according to the report. Having its own advanced, powerful AI models could help Amazon.
