| | ## [Copy link to heading](#about-gpt-realtime-mini)About GPT-Realtime mini GPT-Realtime mini launched on October 10, 2025 at OpenAI's DevDay as the cost-efficient entry in the gpt-realtime family. GPT-Realtime mini responds to audio and text inputs in realtime, covering interactive voice use cases that don't need a flagship model on every turn. The economics are the point. Voice features strain budgets when every session invokes a top-tier model. GPT-Realtime mini exists so in-app assistants, kiosks, and voice helpers can run continuously without the flagship rate, while keeping the low-latency conversational feel that makes voice interfaces usable. Through AI Gateway, GPT-Realtime mini connects over WebSocket using the AI SDK's realtime hook. Your server mints a short-lived token, the browser handles microphone capture and playback through the hook, and AI Gateway applies the same observability and spend controls as your other models. ## [Copy link to heading](#what-to-consider-when-choosing-a-provider)What To Consider When Choosing a Provider - Configuration: Realtime support on AI Gateway is in beta through AI SDK 7, connecting over WebSocket with a short-lived server-minted token. For agents that need heavier reasoning or complex tool chains, step up to `gpt-realtime-1.5` or `gpt-realtime-2`; the mini variant is tuned for cost and speed. - Zero Data Retention: Zero Data Retention is offered on a per-provider and model basis. See the [documentation](https://vercel.com/docs/ai-gateway/security-and-compliance/zdr) for details. - Authentication: AI Gateway authenticates requests using an [API key](https://vercel.com/docs/ai-gateway/authentication-and-byok#api-key-authentication) or [OIDC token](https://vercel.com/docs/ai-gateway/authentication-and-byok#oidc-token-authentication). You do not need to manage provider credentials directly. ## [Copy link to heading](#when-to-use-gpt-realtime-mini)When to Use GPT-Realtime mini ### Best for - High-volume voice features: Per-session cost decides viability and the mini rate keeps features running - In-app voice assistants: Routine questions and commands handled with realtime responses - Voice prototypes: Realtime experiments without committing to flagship pricing - Always-on voice surfaces: Kiosks, devices, and embedded experiences running continuous interaction ### Consider alternatives when - Mission-critical voice agents: `gpt-realtime-1.5` brings stronger instruction following and tool calling - Reasoning-heavy conversations: `gpt-realtime-2` adds configurable reasoning effort for complex workflows - Single-direction audio jobs: `gpt-4o-mini-transcribe` and `tts-1` handle transcription and speech generation directly ## [Copy link to heading](#conclusion)Conclusion GPT-Realtime mini answers the cost question that stalls most voice features. Use the mini variant for high-volume, routine interactions through AI Gateway, and reserve `gpt-realtime-1.5` or `gpt-realtime-2` for the conversations that earn a flagship model.
