Fixie.ai is dedicated to developing AI models that can communicate as naturally as humans. We believe that useful, efficient, and accessible general artificial intelligence (AGI) will require models that can operate within the fast-paced, nuanced world of natural human communication. We are tackling this by building Ultravox, an open-source, state-of-the-art voice-to-voice model; constructing the best stack for real-time communication of LLMs on WebRTC; building new experiences on Town; tracking model and provider latency on TheFastest.ai; and exploring the boundaries of possibility in the field of AI.
