Did xAI just mass-murder the entire voice AI industry? 🤯 Grok just launched two voice APIs. Speech-to-Text and Text-to-Speech. Built on the same stack powering Tesla cars and Starlink support. And priced at 10x cheaper than ElevenLabs. Speech-to-Text: $0.10/hr batch. $0.20/hr streaming. Text-to-Speech: $4.20 per million characters. 25+ languages. Real-time streaming. Speaker diarization. Already outperforming ElevenLabs, Deepgram, and AssemblyAI on word error rate. TTS ships with expressive tags like [laugh], [sigh], , . Voices that don't sound like robots reading a script. ElevenLabs spent years building a voice AI company. xAI built voice AI for cars and satellites.

Neuralink’s next product BlindSight aims to restore vision for people born blind. The implant has already shown success in monkeys. If this scales to humans, it’s not just a breakthrough. It’s millions of lives changed and an entirely new chapter for humanity.

Actually, AI/Robotics will mean everyone can have a penthouse if they want. The output of goods & services will be several orders of magnitude higher than today’s economy. Read the Iain Banks Culture books for the best imagining of how it will be. That said, what is the future you want? Amazing abundance seems the best to me.

A lot of misinformation from legacy media about Starlink’s entry into South Africa. Here’s the truth 👇 • ❌ “Starlink wants to bypass B-BBEE” ✅ False — it supports transformation via EEIP, a legal framework already used by companies like Microsoft, IBM, and Amazon Web Services. • ❌ “Starlink is asking for special treatment” ✅ No — it’s asking for equal rules so ALL satellite operators can compete fairly. • ❌ “EEIP is less beneficial than equity deals” ✅ Reality — Starlink’s plan would connect 5,000 rural schools with FREE high-speed internet, impacting millions of students every year. • ❌ “It won’t create local impact” ✅ It will partner with local businesses, create jobs, and boost the economy (broadband growth = GDP growth). • ❌ “It will become a monopoly” ✅ Impossible — Starlink operates globally in a competitive market across 150+ countries. • ❌ “Security & privacy risks” ✅ It will fully comply with South African laws like every other country it operates in. • ❌ “Starlink is already operating illegally” ✅ Wrong — it is NOT operating because it is still waiting for a license.

Robotaxi now rolling out in Dallas & Houston 🤠

Plug it in. Point at sky. Starlink connects to reliable high-speed internet in minutes, wherever you roam 🛰️❤️

grok 4.3 beta can use an ubuntu shell and a persistent file layer to generate artifacts grok wrote python to encode the xai / grok logo into audio, i gave it the script back and had it render a spectrogram video from that signal, and use the grok_files tool to save the mp4 into the product's files layer i opened the file from the files panel and played it myself this is getting crazy

Grok 4.3 can create PDF and almost any file formats like Sheets, Slides, Doc

Golden era
