About

Eleven Realtime is a developer-facing speech-to-speech API for adding live voice conversations to applications and AI agents. It combines speech recognition, turn-taking, language-model reasoning, and voice generation, with Mini and Max model options for different conversational needs. Developers can use the models through the Realtime API or select them in ElevenAgents. The streaming interface is designed for interactive voice experiences, including assistants, customer support, tutors, and interactive characters. Agent configurations can include prompts, voices, tools, knowledge bases, and conversation flows. Realtime usage is billed per minute plus model input and output tokens. The product is intended for developers and organizations building real-time conversational applications and voice-enabled customer experiences.

About

Higgs Realtime is a production-quality, real-time speech-to-speech model and API built for natural, continuous conversation. It is an end-to-end, instruction-tuned, audio-native model that can understand audio, text, or both and generate high-quality responses, while also functioning as a text LLM when given text alone. Designed for live voice agents, it follows conversations, handles interruptions, adapts when requests change mid-sentence, and carries multi-step workflows through to completion. The model is trained specifically for voice-agent reflexes such as natural turn-taking, conversational cadence, tone adaptation, spoken tool preambles, multi-turn state tracking, and robust instruction following through changing requests. Semantic turn detection helps distinguish a completed turn from a pause, while multilingual and code-switched understanding supports more than 100 languages without per-language setup.
