AI API Router Directory

ChatAnywhere is a widely used free LLM relay. Users bind a GitHub account to get a free API key and access GPT-4o, Claude, and Gemini models through an OpenAI-compatible interface, optimized for access from mainland China.

GitHub-bound free key: 10,000 points/day with per-model caps (GPT-5/4o/4.1 5/day, DeepSeek 30/day, mini models 100/day, ~200 req/day total) ≈ $2/mo; personal non-commercial use only.

Hyperbolic (hyperbolic.xyz) is the API-specific endpoint for Hyperbolic's AI cloud. It provides serverless inference for over 25 open-source models through an OpenAI-compatible /v1 endpoint. The platform supports text, image, and audio generation with pay-as-you-go pricing.

~$1 trial credit for new users (DeepSeek V3, Llama 3.1 405B, Qwen); pay-as-you-go after it is used (Llama 405B ~$4/M, DeepSeek R1 ~$3/M tokens).

DeepSeek's official API serves the current V4.1-Flash and V4-Pro models with 1M-token context and 384K max output, from $0.15/$0.60 per 1M in/out off-peak (Flash) — peak hours bill at 2x, cached input drops to $0.003/M. One key exposes both an OpenAI-compatible and an Anthropic-compatible endpoint, and sign-up grants a free token balance that is deducted before any top-up.

Free 'granted balance' of ~5M tokens at sign-up (deducted before top-ups per official billing rules); $0.70 is an estimate at V4-Flash off-peak rates.

LlamaGate could not be verified on any official domain as of 2026-09-16. The domain in this listing, llamagate.ai, does not resolve at all, and the alternative domain found in a third-party integration library, llamagate.dev, returns only a LiteSpeed web-server 404 on its root, /pricing, /docs and on api.llamagate.dev/v1/models - the host answers, but no product page, pricing page or API response is served. Because no vendor-owned page could be retrieved, this entry deliberately makes no pricing, model or free-tier claims; third-party descriptions of the product were not used as a source.

No free tier stated on official pages (checked 2026-09-16): llamagate.ai does not resolve and llamagate.dev returns 404 on root, /pricing, /docs and api.llamagate.dev/v1/models, so no free allowance or price could be verified.

ModelScope (魔搭, modelscope.cn) is an open-source model and dataset community founded in June 2022 by the Institute for Intelligent Computing together with the CCF Open Source Development Committee, organised around 'Model-as-a-Service'. The platform publishes models, datasets, Studios (application display space), MCP and Skills listings, and maintains the ModelScope, Swift, EvalScope and ModelScope-Agent frameworks. Its stated free offering is platform credits: 'Sign up / Log in to get 200 Magicubes' plus 'Link Alibaba Cloud account, get 50 more daily', with Studios described as 'a free and flexible AI application display space'.

No cash value stated: the official home page says 'Sign up / Log in to get 200 Magicubes' and 'Link Alibaba Cloud account, get 50 more daily' (modelscope.cn, checked 2026-09-16); Magicubes have no published CNY or USD rate.

Tencent Yuanbao (yuanbao.tencent.com) — Tencent's free consumer AI assistant built on the Hunyuan (混元) family; current version serves Hunyuan Hy4 preview with upgraded Agent capabilities, plus a DeepSeek R1 inference option. Unofficial browser/cookie integration.

A free tier is available; the exact credit value is not quantified.

UnoRouter is a unified AI API platform providing access to hundreds of models through a single intelligent endpoint. It is fully OpenAI-compatible and supports various clients including coding agents, character chat, and CLI tools. Features both pay-as-you-go and subscription plans with credit bonuses.
