Google AI Studio vs Vapi

专项更强Provides raw frontier language models and real-time multimodal capabilities, requiring custom scaffolding compared to Vapi's voice workflows.

超拟真语音克隆与语音合成领域的行业领导者，现在也提供强大的对话式语音代理功能。

一个 API 密钥，调用各大厂商数百个 AI 模型

智谱 AI 的 GLM 大模型开放平台，多模态 API 与智能体开发一体化

免费 / 开源Google 的轻量级开放权重 AI 模型家族

专项更强一个 API 接入 1500+ 生产级生成式媒体模型

通过开发者 API 提供超低延迟的语音合成与受管理的语音代理，足以媲美 Vapi 的语音速度。

专项更强Together AI is the AI Native Cloud — a full-stack platform for running, fine-tuning and training open-source models. It spans serverless inference APIs, dedicated endpoints, GPU clusters, post-training and storage, all backed by in-house systems research.

专项更强Replicate is a cloud API for running, fine-tuning, and deploying machine learning models. Spin up open-source and hosted models — from image, video, and audio generation to speech synthesis, captioning, and LLM inference — with one line of code, or package your own model with Cog and put it behind a production-ready API.

提供强大的实时语音转文字与语音代理 API，不过针对电话语音的编排功能比 Vapi 少一些。

免费 / 开源面向 200+ 开源模型的低成本无服务器推理 API

专项更强Provides enterprise-grade speech-to-text and audio intelligence APIs, but lacks turnkey conversational voice agent telephony orchestration.
