Grok Adds Custom Voice on X Platform
Grok, the AI from xAI, is rolling out a Custom-Voice feature inside the Grok app that lets users tailor a voice by prompts. Users can configure voice attributes such as name, style, and instructions, with examples like calm and beautiful, and influence the voice's tone via free-text prompts. The update brings voice personalization directly into Grok’s interface and positions Grok as a voice-enabled assistant within the X ecosystem, alongside comparisons to OpenAI’s Voice Mode and Whisper. Availability is limited: the Custom-Voice feature is not yet live in the EU or the United Kingdom. Grok 3 remains accessible to all users. The article highlights potential implications for creators and brands on X, noting that personalized AI voices could enhance branded content and interactive responses, while also raising questions about transparency and voice provenance.

OpenAI Fires Safety Researchers; GPT-6.1 Ultrafast Launch
This AINews newsletter covers several significant developments: OpenAI has fired three safety researchers linked to a METR audit, citing mishandling of confidential information. OpenAI also launched GPT-6.1 Sol Ultrafast, a faster and cheaper model, and introduced an intelligent UI for ChatGPT. Anthropic released Claude Haiku 5.5 and cut Sonnet 5.5 cache-read prices.

AI Price War: OpenAI Gains Ground on Anthropic
The AI price war is intensifying, with OpenAI gaining significant ground on Anthropic among business customers. According to a Wall Street Journal report, spending on OpenAI and Anthropic models via the OpenRouter platform was nearly evenly split in September among roughly 120,000 companies using both, a shift from January when Anthropic held about 75% of that spending. OpenAI's aggressive price cuts on its GPT-5.6 lineup, including an 80% reduction on its smallest model Luna and 20% on Terra, are driving this change. Companies are increasingly prioritizing cost, combining multiple providers and using cheaper models for simpler tasks. Anthropic faces its own challenges, including capacity issues with Claude Code and data retention criticism. Both companies are preparing for IPOs, needing to demonstrate sustainable revenue to justify valuations exceeding $1 trillion.
