Amazon’s cloud computing arm,Amazon Web Services(AWS), has lost a senior executive from its generative artificial intelligence division, a report has said. Vasi Philomin, a key vice president overseeinggenerative AIdevelopment and the company’s Bedrock service, has left the company. Philomin, who had been withAmazonfor eight years, confirmed his move to another company via email to news agency Reuters.Philomin played a crucial role in leading AWS’s generative AI efforts, product strategy, and oversaw the development of Amazon’s foundation models known as Amazon Titan. He played aninstrumental role in creating and leadingAmazon Bedrock, a central hub for utilising various AI models and a flagship product in AWS’s quest for AI dominance. Philomin was also a regular speaker at major AWS events, including the company’s annual cloud computing conference in Las Vegas.An Amazon spokesperson confirmed his departure earlier in June and stated that Rajesh Sheth, a vice president formerly in charge of Amazon Elastic Block Store, has assumed some of Philomin’s responsibilities. The spokesperson also noted that other vice presidents at AWS are actively working on generative AI projects.This high-profile exit comes as Amazon intensifies its efforts to bolster its standing in the rapidly evolvingAI developmentlandscape. Rivals like OpenAI and Google have gained an early lead, particularly with consumer-focused AI models.To compete, the Seattle-based tech giant has made huge investments, including an $8 billion investment in AI startup Anthropic. This partnership has led to the integration of Anthropic’s Claude software into Amazon’s own products, notably a revamped version of its voice assistantAlexa, which is being rolled out to customers this year. Amazon has also been expanding its own AI model portfolio, introducing Nova AI models for text, video, and image generation in December, and later adding Sonic for natural-sounding speech this year.
