Introducing GPT-Live
A new generation of voice models for natural human-AI interaction, now powering ChatGPT Voice.
A new voice model called GPT-Live enables more natural conversations with AI by using full-duplex architecture, which allows the system to listen and speak simultaneously while making interaction decisions many times per second. Unlike previous voice systems that processed conversation in separate steps or discrete turns, GPT-Live maintains continuous conversation flow, can acknowledge what users say with natural phrases, and delegates complex tasks like web search to backend models while keeping the conversation going. The system is being rolled out to ChatGPT users globally in two versions, GPT-Live-1 and GPT-Live-1 mini, and shows improvements in human evaluations measuring conversational flow, turn-taking, and naturalness compared to earlier voice modes. This advancement represents a shift toward more fluid human-AI interaction where reasoning and complex work happen in the background while maintaining responsive dialogue.

Runway’s Praxis-1 world action model for robotics is now available
Praxis-1 builds on Runway’s work as a founding member of the Cosmos Coalition, advancing open world models for physical AI. | Source: Runway Runway AI Inc. yesterday released Praxis-1, its world action model for robotics. The model is now available to developers with open weights under the Apache 2.0 license. Runway first announced Praxis-1 in September with launch partners including Noble Machines, Standard Bots, and Ultra. Since then, these companies have been running the model on their own ha
Google releases Gemini 4 Carbon with agent ‘swarm’ feature
Google is rolling out its latest AI model, Gemini 4 Carbon, to the general public after releasing it to a select group of "cybersecurity defenders" two weeks ago. Google claims Carbon is its "strongest model" yet, and capable of competing with the very best systems from Anthropic and OpenAI. Google says Gemini 4 Carbon "pushes the frontier even further" than Argon, referring to the company's other frontier model that launched only last month. The company said Argon will likely
Gemini 4 Carbon is now available
The latest version aims to deliver improved performance while reducing the computational resources and energy required for AI operations.
Google Launches Gemini Decisions API With Gemini Decision 1 at $0.10/M Tokens
Google has launched the Gemini Decisions API, powered by a new model, Gemini Decision 1 (gemini-decision-1). The Gemini Decisions API does not generate text. It scores up to 1,000 typed questions against one shared input and returns calibrated probabilities. For developers, this targets the small branching calls inside agents: routing, policy checks, tool selection and grading. Google prices it at $0.10 per 1M input tokens, with zero output tokens billed. TL;DR Size: Context is 262,144 t
