OpenAI replaces ChatGPT's turn-based voice system with the full-duplex GPT-Live-1 model. It speaks and listens simultaneously, interrupts less, handles pauses, routes complex queries to top text models, adds visuals, and supports real-time translation. The upgrade reaches iOS, Android, and web for paid subscribers, with a mini version for free users.

OpenAI has revamped the voice capabilities in ChatGPT by introducing the GPT-Live-1 model, which the company describes as feeling more like “talking to another person.”

OpenAI replaces turn-based voice with full duplex GPT-Live-1. The updated system reportedly interrupts speakers less frequently and pauses to let users resume if they hesitate during talks. During a press briefing, OpenAI research lead Kundan Kumar described GPT-Live-1 as the company’s “smartest voice model” yet.
What it really means is that it can speak and listen at the same time.

ChatGPT had previously depended on an older, turn-based voice model. “This is a full duplex model,” OpenAI product lead Atty Eleti said. “What it really means is that it can speak and listen at the same time.”

GPT-Live-1 routes complex queries to top text models and adds visuals. The model will hand off requests to leading text systems such as GPT-5.5 whenever deeper reasoning or web searches become necessary. Conversations covering topics like the weather, stocks, and sports will now include AI-generated visuals that display related details.
The full-duplex approach enables capabilities such as live translation even as the speaker continues.

Tesla and SpaceX confirm Terafab chip fab in Texas

Tesla and SpaceX have confirmed Grimes County, Texas as the site for their Terafab semiconductor megafactory, with the first phase costing roughly $16.8 billion. The project targets the largest chip manufacturing facility on the planet to supply over 1 terawatt of compute per year that exceeds current and future global production capacity.

OpenAI Urges Federal Judge to Throw Out Apple's Trade Secrets Complaint

OpenAI has filed a motion asking a federal judge to dismiss Apple's trade secrets lawsuit, describing the claims as meritless. The dispute, which follows a July suit and this week's injunction request from Apple, highlights tensions after their prior partnership on Siri and OpenAI's hardware push.

Meta introduces Muse Code, its terminal-based coding agent

Meta has released an early beta of Muse Code, a terminal-based coding agent driven by the updated Muse Spark 1.2 model and positioned against Anthropic's Claude Code and OpenAI's Codex. Substantially lower rates, including a contributor plan at $0.10 for every million tokens received, may encourage migration away from higher-priced options such as Anthropic's Sonnet 5.
