Positioning brief — for the ElevenLabs Agents team
Why the models put ElevenLabs Agents at #3 for speech-to-speech apis for real-time voice assistants
- Best-in-class voice quality and expressiveness GPT · Claude · Gemini · Grok“Best-in-class voice quality and voice cloning”
- Full real-time agent platform GPT · Claude · Grok“wrapped in a full conversational agent API”
- Telephony, workflow, and observability tooling GPT · Claude“telephony and SIP integrations, workflow tooling, observability, evaluations, and broad client SDK support”
- Production scale across 70+ languages Grok“low-latency interactions in 70+ languages; proven in production customer support and scalable deployments”
What the models credit OpenAI Realtime API (#1) with — and don’t credit ElevenLabs Agents
- Native end-to-end speech-to-speech Claude · Gemini · Grok“Native end-to-end speech-to-speech”
- Strong reasoning and tool calling GPT · Claude · Grok“strong reasoning and tool calling”
- Deepest integration ecosystem Claude“the ecosystem (LiveKit, Pipecat, Twilio integrations) is the deepest of any option”
What would move the rank — the models’ fix lines, unified
- Pipeline latency trails native models Claude · Gemini · Grok“Slower response times due to pipeline latency compared to native models”
- Expensive for high-volume use GPT · Claude · Gemini“expensive per-minute pricing that scales poorly for high-volume customer service”
- Less model-level control GPT · Grok“teams needing maximum model-level control or lowest unit cost may outgrow it”

The strongest turnkey choice for production voice agents, combining highly expressive voices, low-latency streaming, telephony and SIP integrations, workflow tooling, observability, evaluations, and broad client SDK support
Claude Best-in-class voice quality and voice cloning wrapped in a full conversational agent API (turn-taking, interruption handling, RAG, tool calls, telephony), with LLM flexibility — you bring GPT/Claude/Gemini as the brain; ideal when voice naturalness is the product.
Gemini Unmatched voice quality and expressiveness, offering incredibly realistic human-like delivery (including laughter and sighs) alongside high-fidelity voice cloning.
Grok Exceptional voice quality, expressiveness, and cloning with solid real-time agent platform for low-latency interactions in 70+ languages; proven in production customer support and scalable deployments.
Where ElevenLabs Agents falls short, per the models
- GPT It is a more opinionated hosted pipeline than a frontier native speech-reasoning API, so teams needing maximum model-level control or lowest unit cost may outgrow it
- Claude It's a cascaded STT→LLM→TTS orchestration rather than true end-to-end speech-to-speech, so latency and prosody-awareness trail native audio models, and per-minute pricing is steep for high-volume use.
- Gemini Slower response times due to pipeline latency compared to native models, and expensive per-minute pricing that scales poorly for high-volume customer service.
- Grok Pipeline-based (STT+LLM+TTS orchestration) leads to higher end-to-end latency vs native S2S; less seamless for deep reasoning/tool use without additional layers.
Top alternatives per the models: OpenAI Realtime API · Gemini Live API · Hume EVI · Inworld Realtime API
The most complete self-serve voice agent platform in 2026 — best-in-class TTS/voices, built-in STT and LLM orchestration, RAG knowledge bases, tool calling, SIP/Twilio telephony, agent testing/evals, and 30+ languages, so a typical support team can ship a production phone agent in days without stitching vendors together; assumes the practitioner wants a managed end-to-end stack rather than composing their own.
GPT Outstanding voice quality and multilingual range, backed by visual workflows, telephony, tool calling, guardrails, analytics, A/B experiments, and unusually strong automated conversation testing.
Where ElevenLabs Agents falls short, per the models
- GPT Voice and LLM costs are separately metered, and contact-center integration depth trails PolyAI.
- Claude Model/pipeline flexibility is thinner than developer-first rivals — you're largely inside ElevenLabs' stack, and heavy custom conversation logic or deep CCaaS/CRM workflows take more work than on purpose-built contact-center products.

Top alternatives per the models: Retell AI · Vapi · PolyAI · LiveKit Agents
End-to-end conversational AI platform riding the best TTS in the market — agent builder, knowledge base/RAG, tool calls, SIP telephony, and multilingual voices in one place, making it the fastest route from idea to a natural-sounding agent.
GPT Best-in-class voice quality and multilingual breadth paired with telephony, mobile and web SDKs, visual workflows, tools, analytics, A/B testing, and unusually capable automated agent tests.
Where ElevenLabs Agents falls short, per the models
- GPT Best value depends on prioritizing ElevenLabs’ voice stack; cost and platform coupling are weaker fits for voice-agnostic teams.
- Claude Locks you into the ElevenLabs voice and orchestration stack — you can't swap in a cheaper TTS or restructure the pipeline, and per-minute pricing runs high at call-center volumes.

Excellent voice quality with scheduled batch calling, personalization, visual workflows, testing, analytics, and native Google Calendar actions at competitive self-serve pricing
Claude Best-in-class voice realism now wrapped in a full conversational-agent platform with telephony, tool-calling, and turn-taking — the strongest choice when call quality and human-sounding delivery drive booking conversion.
Where ElevenLabs Agents falls short, per the models
- GPT Outbound campaign and appointment-operations tooling is less mature and turnkey than the top three, often requiring external telephony and additional workflow assembly
- Claude Younger as an end-to-end agent/orchestration platform than the purpose-built booking tools, so complex multi-step scheduling flows and campaign management are less mature, and premium voice adds cost.

Best-in-class voice quality and turn-taking naturalness, aggressive per-minute pricing, built-in RAG/knowledge base, multilingual coverage, and telephony support turned it from a TTS vendor into a credible full agent platform; ideal when caller experience quality is the differentiator.
Where ElevenLabs Agents falls short, per the models
- Claude Contact-center operational depth (routing, agent-assist handoff, compliance tooling, enterprise analytics) trails the CCaaS-grade players — less suited to large regulated support operations.
