ElevenLabs Conversational AI
Also known as: ElevenLabs, ElevenLabs Agents
Conversational AI and voice agent platform with WebRTC tool-calling, stateful conversations, evaluation support, PAYG pricing, and developer-accessible APIs and SDKs.
ElevenLabs is an AI research and product company that has become a kind of audio layer for the internet, generating lifelike speech and powering voice-based AI agents. Founded in 2022 and launched the following year with one of the first convincingly human AI voice models, it built its reputation on text-to-speech that captures emotion, pacing, and nuance rather than sounding robotic, and has since expanded into a full audio stack used by creators, businesses, and developers.
Its text-to-speech models span a range of needs, from a highly expressive model that responds to inline cues like laughter or whispering for narration and dramatic work, to ultra-low-latency models built for real-time conversation. Around this sit a large library of ready-made voices, voice cloning that can recreate a person's voice from a short sample, voice design from a text prompt, speech-to-speech voice changing, and dubbing that re-voices content across many languages while preserving timing and delivery. A speech-to-text model handles accurate transcription with speaker labels and word-level timestamps.
For agentic use, ElevenLabs offers a conversational AI platform, ElevenAgents, that combines speech recognition, a language model, and its own speech synthesis into a single low-latency stack for building, deploying, and monitoring voice and chat agents. Because the platform is designed for production, it includes the testing, monitoring, and reliability features teams need to run agents at scale, and its low-latency voices are also embedded inside many other companies' voice products and contact-center systems.
Everything is accessible through an API with Python and TypeScript SDKs and streaming endpoints, alongside a studio editor for long-form audio, music generation, and a reader app, all spanning dozens of languages. For enterprises, ElevenLabs carries SOC 2, ISO 27001, PCI, GDPR, and HIPAA-eligible posture, with and zero-retention options for sensitive workloads. The company is also vocal about responsible use, monitoring misuse of its voice technology. In practice, ElevenLabs is both a creative tool for generating speech, music, and dubbing, and the underlying voice infrastructure that lets conversational agents sound human.

In practice
You're building a voice agent and the synthetic voice sounds flat and laggy. ElevenLabs supplies ultra-low-latency, expressive speech, and its ElevenAgents platform bundles speech recognition, a model, and that voice into one stack you can deploy and monitor.
You want to localize a video into a dozen languages without re-hiring voice talent. ElevenLabs dubs the content across languages while keeping the timing and the original speaker's delivery, so it still sounds like the same performer.
Your audiobook or ad needs narration that conveys real emotion. ElevenLabs' expressive model reads the script with controllable pacing and inline cues for things like whispering or laughter, in a cloned or library voice you choose.

Recent platform changes
ElevenLabs introduced several new capabilities to ElevenAgents, including a knowledge base system tool, WebSocket support for custom LLMs, and Voice Activity Detection (VAD) configuration. The update also adds DTMF input redaction, translated workflow messages, version filters, and per-test tool mocks.
Bears on: Agent capability
View sourceElevenLabs JS and Python SDK v2.53.0 added conversation evaluation rerun support, workflow entry_behavior and end-procedure tools, telephony filters, and expanded agent test batch limits.
Bears on: Workflow orchestration
View sourceElevenLabs changed the default conversational ASR provider from elevenlabs to scribe_realtime and added conversation_product to conversation details responses.

View sourcePricing
Free tier (15 agent minutes/mo); paid from $6/mo Starter up to $990/mo Business; overage $0.08/min; Enterprise custom
hybrid (subscription tiers with included agent minutes, then per minute overage)
Included quota
Free: 15 agent minutes, 4 concurrent, no commercial license. Starter ($6): 75 min, 6 concurrent. Creator ($22): 275 min, 10 concurrent. Pro ($99): 1,238 min, 20 concurrent. Scale ($299): 3,738 min, 30 concurrent. Business ($990): 12,375 min, 40 concurrent. Enterprise: custom.
What is public
All tier prices, included agent minutes and concurrency, the $0.08/min overage, and the $0.16 burst rate are public. Enterprise is custom.
Billing mechanics
ElevenAgents plans bill by call minutes, not the shared character credit pool. Each tier includes a bundle of agent minutes and a concurrency limit; beyond the bundle, minutes cost $0.08 each, rising to $0.16 when you exceed concurrency. Text messages are about $0.003 each. The reasoning model and telephony are passed through and billed separately. Silence over 10 seconds is discounted 95%. Annual billing saves about 17%.
Cost watchouts
The reasoning model and telephony provider are billed separately and are not in the plan price, so effective cost per minute runs above $0.08. Conversation duration bills on connection time including silence (discounted after 10 seconds), and the free tier has no commercial license.
Variable cost rationale
Agent usage bills by call minute against a plan bundle, then per minute overage, and the underlying language model and telephony are passed through separately, so effective cost scales with conversation volume and model choice.
Additional watchouts
Budget for the separately billed model and telephony on top of the plan and $0.08 overage, and watch concurrency limits that trigger the doubled $0.16 burst rate during spikes.
Overage / add-ons
Beyond the included minutes, agent time bills at $0.08/min, or $0.16/min when you exceed your plan's concurrency limit. LLM and telephony are billed separately on top.
Sales call required
Mixed (some tiers require a call)
Free / trial
Free tier: 15 agent minutes/mo, 4 concurrent calls, no commercial license
Lowest paid plan
Starter $6/mo (75 agent minutes)
Commercial notes
ElevenLabs (founded 2022, New York and London) is best known for high fidelity voice; ElevenAgents is its conversational AI platform competing with Vapi, Retell, and Bland. RAG is built in and you can bring your own model. Enterprise adds custom SLAs, SSO, HIPAA with BAA, and volume discounts.
Key ambiguities
The pass through model and telephony costs depend on model and carrier choice, so total per minute cost is configuration dependent even though ElevenLabs' own rates are exact.
