Big Speak vs New API

Side-by-side comparison · Updated October 2026

 Big SpeakBig SpeakNew APINew API
DescriptionBigSpeak is an advanced AI-powered voice generation platform that offers a suite of features such as Text to Speech, Speech to Text, Text to Video, and Voice Cloning. Users can create realistic sounding audio from text, access different voice categories, and choose from multiple languages and voice actors. With both free and premium plans, it provides options for diverse needs, including up to 100,000 characters per month and advanced support for premium users, along with high-quality voice generation and transcription services.New API is a self-hosted AI gateway and model-management project maintained in the QuantumNous repository. It brings provider channels, access tokens, model restrictions, usage statistics and cost accounting into one interface. Teams supply their own authorized model-provider access and operate the gateway in their chosen environment. The gateway supports several API formats, including OpenAI-compatible requests, Claude Messages and Google Gemini. Compatibility has boundaries: the README marks Gemini-to-OpenAI conversion as text-only without function calling, and OpenAI-compatible to Responses conversion as in development. Test the exact endpoints, streaming behavior and tool calls your application uses before switching traffic. Routing features include weighted channel selection, automatic retry after failures and user-level model rate limits. The dashboard supports request-based, usage-based and cache-hit cost accounting, with token grouping and model-access controls. These controls can help organize usage, but retries and a common API format do not guarantee uninterrupted service or identical behavior across providers. The current repository license is AGPLv3. Docker Compose is the recommended quick-start path in the README, which also documents Docker commands with SQLite or MySQL. Running the software still involves infrastructure, operations and upstream model charges. Review the current license, secure your deployment and validate accounting against provider bills. Compare LiteLLM if you also want a Python SDK or a documented gateway for MCP servers and agents.
