AI company Sesame has released the base model that powers Maya, the impressively realistic voice assistant. The model, which is 1 billion parameters in size (“parameters” referring to individual components of the model), is under an Apache 2.0 license, meaning it can be used commercially with few restrictions. Called CSM-1B, the model generates “RVQ audio codes” from text and audio inputs, according to Sesame’s description on the AI dev platform Hugging Face. RVQ refers to “residual vector quantization,” a technique for encoding audio into discrete tokens called codes. RVQ is used in a number of recent AI audio technologies, including Google’s SoundStream and…

Meta is reportedly testing an in-house chip for training AI systems, a part of a strategy to reduce its reliance on hardware makers like Nvidia. According to Reuters, Meta’s chip, which is designed to handle AI-specific workloads, was manufactured in partnership with Taiwan-based firm TSMC. The company is piloting a “small deployment” of the chip and plans to scale up production if the test is successful. Meta has deployed custom AI chips before, but only to run models — not train them. As Reuters notes, several of the company’s chip design efforts have been canceled or otherwise scaled back after…
