Grok Voice Agent API

What it does

Grok Voice Agent API lets developers build real-time voice agents using xAI's in-house stack (VAD, tokenizer, audio models). It features <1s latency, function calling, and native multilingual support.

Bringing the power of Grok Voice to all developers.

Today, we're excited to launch the Grok Voice Agent API, empowering developers to build voice agents that speak dozens of languages, call tools, and search realtime data. The Grok Voice Agent API is built on the same stack that powers Grok Voice for millions in our mobile apps and Tesla vehicles, and we’re thrilled to open up this proven technology to all via the xAI API. Grok Voice Agents are the fastest, most intelligent voice agents available on the market. We built the entire voice stack in-house, training our own voice activity detection (VAD), tokenizer, and audio models from scratch. This fine-grained control over every component of the stack allows us to rapidly iterate and improve…from x.ai

  22 GB of Hacker News in SQLite▲730

  Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite&#x2F;wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https:&#x2F;&#x2F;github.com&#x2F;DOSAYGO-STUDIO&#x2F;HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
