If a developer wants to make a competing product, it would behoove them not to give money to their biggest competition.
Additionally, Amazon is providing access to its own AI model, Titan. Developers interested in using Amazon’s models will have to use AWS.
Amazon also has developed its own chips designed for training AI models and producing inferences, i.e., responses to prompts, dubbed Trainium and Inferentia, respectively. The chips are specially designed to reduce workloads and save money on computing. So using AWS could be less expensive for many developers than its competition. It’s worth noting, however, that both Microsoft and Google have their own chip designs for AI training.
