Ultravox AI
@ultravox_dot_ai
We're building AIs that can communicate as naturally as humans: http://ultravox.ai
We just launched new subscription plans. The highlight? 𝗨𝗻𝗹𝗶𝗺𝗶𝘁𝗲𝗱 𝗰𝗼𝗻𝗰𝘂𝗿𝗿𝗲𝗻𝗰𝘆 for all paid plans. No caps. No surge pricing. Scale is built in. ultravox.ai/pricing
Voice AI, the enterprise way. Hexaware partners with @FixieAI to deliver faster, sharper customer conversations using Ultravox Realtime. Deployed where accuracy, scale, and uptime are non-negotiable. Read more: bit.ly/4kE7y8h #VoiceAI #EnterpriseAI #UltravoxRealtime…
I’m using Ultravox from @FixieAI to build AI agents for call centers and the healthcare industry, and for me, it’s the best. They offer very advanced tool calls and a design pattern called “stages,” similar to agent orchestration in traditional LLMs. Plus, you can manage state…
⚡ Voice AI that responds in 600ms? Meet Ultravox — a multimodal LLM from @FixieAI that skips the STT step and processes audio directly into an LLM. Built on @cerebriumai infra, deployed with Pipecat from @trydaily
It's been great working with the @11x_official team to help bring Julian to life (built on top of Ultravox!). Check him out:
Lead outreach will never be the same. We know we’ve been quiet—but for good reason. We’ve been heads-down building something big that’ll transform your entire go-to-market strategy. Meet Julian, the world’s first voice digital worker, built exclusively for go-to-market teams.…
so, the @OpenAI realtime API is actually probably the worst realtime audio option on the market. Gemini's multimodal beta blows it out of the water in terms of voice quality, intelligence, and instruction following, and @FixieAI / Ultravox kicks ass too. gpt-4o-realtime-preview…
Building real-time WebRTC and Websocket applications is very difficult to get right in Python. Until now - Introducing FastRTC, the realtime communication library for Python ⚡️

Watch our CEO @zachk talk with @davitb from @krispHQ about the future of Realtime Voice AI and what we're doing with Ultravox to make it possible
Speech-to-speech models are redefining Voice AI models. They’re faster, smarter, and make human-bot conversations feel more natural. Perfect for CX, team collaboration, and robotics. In my chat with @zachk, CEO @fixieai, we unpacked how Fixie is building game-changing…
Clearer conversations, smarter communication! 💬✨ Krisp is partnering with Fixie.ai to enhance Ultravox Realtime with AI Noise Cancellation, ensuring seamless Voice AI conversations anywhere and noise-free. 🚀 Learn more: 👉 krisp.ai/blog/krisp-ext…

Nice to see @OpenAI continuing to follow in our footsteps! :) I'll just point out that: * We're still cheaper * We're still open * We have more voices * We're just as fast (if not faster!)
That’s it. That’s the tweet. The Realtime API now supports WebRTC—you can add Realtime capabilities with just a handful of lines of code. We’ve also cut prices by 60%, added GPT-4o mini (10x cheaper than previous prices), improved voice quality, and made inputs more reliable.
