GPT-5 Available in ElevenLabs Conversational AI

OpenAI's GPT-5, the most advanced model for coding and agentic tasks, is now integrated into ElevenLabs Conversational AI, enabling voice agents with unprecedented intelligence for complex enterprise workflows and customer interactions.

Introduction

GPT-5 is now available across the ElevenLabs Conversational AI platform, offering developers immediate access to the most capable language model we've ever integrated.

With its 74.9% score on SWE-bench Verified and 96.7% on τ2-bench telecom, GPT-5 transforms what's possible with voice AI agents.

Key Advantages for Voice AI

Superior Intelligence: GPT-5's advanced reasoning enables agents to handle complex multi-step queries, maintain context across extended conversations, and navigate intricate business logic with precision that matches human agents.

Revolutionary Tool Calling: Scoring 96.7% on τ2-bench (versus sub-49% for previous models), GPT-5 reliably chains dozens of API calls to complete complex tasks—from multi-system order processing to coordinating appointments across calendars.

Optimized for Real-time Voice: New features like minimal reasoning mode and adaptive verbosity control ensure natural conversation flow. Agents can provide quick confirmations or detailed explanations as needed, without explicit prompting.

80% Fewer Errors: GPT-5's dramatically improved factual accuracy makes it ideal for high-stakes applications in healthcare, finance, and technical support where accuracy is critical.

Transformative Use Cases

The combination of GPT-5's capabilities with ElevenLabs' ultra-low latency voice synthesis enables entirely new applications:

• Technical Support: Agents that debug multi-system issues, understand error logs, and generate code fixes during the conversation
• Healthcare Navigation: Complex insurance verification, multi-provider scheduling, and prescription management with enhanced medical accuracy
• Enterprise Automation: Voice assistants that execute complete workflows like employee onboarding or procurement processes
• Consultative Sales: Dynamic pricing calculations, inventory checks, and proposal generation during customer calls

Getting Started

1. Access your Conversational AI dashboard
2. Select GPT-5, or the mini/nano variant, from the Language Model dropdown
3. Deploy your optimised agent immediately

Existing agents can be upgraded with a single setting change. New users can sign up for an ElevenLabs account to start building with GPT-5 today.

Enterprises can now automate complex, high-value interactions that previously required skilled human agents, while delivering superior customer experiences through more natural, capable, and reliable voice interactions.

The GPT-5 integration is live now, in UI, via API or via our SDKs.
