Sesame Releases Open Source Voice AI Model with Few Safety Restrictions

AI company Sesame has open-sourced CSM-1B, the base model behind its realistic virtual assistant Maya, under a permissive Apache 2.0 license allowing commercial use. The 1 billion parameter model generates audio from text and audio inputs using residual vector quantization technology, but lacks meaningful safeguards against voice cloning or misuse, relying instead on an honor system that urges developers to avoid harmful applications.

OpenAI Advocates for US Restrictions on Chinese AI Models

OpenAI has submitted a proposal to the Trump administration recommending bans on "PRC-produced" AI models, specifically targeting Chinese AI lab DeepSeek which it describes as "state-subsidized" and "state-controlled." The proposal claims DeepSeek's models present privacy and security risks due to potential Chinese government access to user data, though OpenAI later issued a statement partially contradicting its original stronger stance.
