Microsoft has unveiled two new AI models: MAI-Voice-1 AI, a "lightning-fast" speech generator capable of producing a minute of audio in less than a second on a single GPU, and MAI-1-preview, designed for responding to everyday queries. Microsoft emphasizes that these models, powered by around 15,000 Nvidia H100 GPUs, demonstrate its ambition to build a self-reliant AI ecosystem, potentially reducing its dependence on OpenAI in the future.
